SEATREK SAILING ADVENTURES: EXPEDITION CRUISE DENGAN PINISI OMBAK PUTIH DAN KATHARINA DI INDONESIA TIMUR

SeaTrek Sailing Adventures adalah operator expedition cruise yang menjalankan pelayaran small-ship di Indonesia menggunakan dua kapal pinisi:

• Ombak Putih;
• dan Katharina.

Current website states that SeaTrek has connected travellers through traditional pinisi journeys since 1986.

The company focuses on:

• eastern Indonesia;
• snorkelling;
• wildlife;
• culture;
• remote islands;
• expert-led expeditions;
• family adventures;
• private charters;
• and conservation-oriented travel.

The official site was highly active in July 2026, with new stories dated 16 and 27 July 2026, current cruise schedules, 2026 copyright and current booking policies.

SeaTrek should be distinguished from:

• vessel owner;
• vessel operator;
• broker;
• harbour agent;
• local guide;
• national park;
• airline;
• hotel;
• insurer;
• and conservation partner.

The charter agreement itself uses separate terms:

• OWNER;
• CHARTERER;
• Broker;
• Captain;
• and Crew.

This indicates that the consumer brand may coordinate or broker a cruise while a vessel-owning entity becomes the contractual owner for a specific charter.

The current website does not publicly display one legal company name covering all operations.

Historical online records refer to PT Ombak Putih, but those records are old and do not prove the current contracting entity in 2026.

For publication, legalName should remain Unverified Current.

History

SeaTrek’s official timeline begins with the idea of pinisi travel in the late 1970s.

The company states that it has offered expedition travel since 1986.

Its timeline includes:

• Pinisi Nusantara activity in the 1980s;
• construction of Katharina in the 1990s;
• Ombak Putih joining the fleet in 2012;
• WWF Signing Blue partnership in 2017;
• awards in 2018, 2023, 2024 and 2026;
• and launch of Sailing for Good in 2025.

The timeline is company-published and should be used as historical self-report.

Individual dates, vessel ownership and predecessor companies require registry and maritime records.

Long history is meaningful, but it does not replace current safety and legal evidence.

Ombak Putih

Ombak Putih is the larger vessel.

Official website specifications state:

• length: 42 metres;
• guest capacity: 24;
• guest cabins: 12;
• crew: around 14;
• captain: Jufri on the current profile.

The vessel is a traditional wooden pinisi adapted for passenger cruising.

Cabins are marketed as comfortable and air-conditioned.

Guest should request:

• current layout;
• cabin size;
• bathroom;
• ventilation;
• emergency route;
• and vessel certificate.

A beautiful traditional design does not eliminate the need for modern safety, maintenance and insurance.

The official site says the vessel mostly motors to maintain schedule and raises sails when conditions allow.

This is a useful clarification: the experience is not purely wind-powered sailing.

Katharina

Katharina is the smaller vessel.

Official specifications state:

• length: 38 metres;
• guest capacity: 12;
• guest cabins: 6;
• crew: around 12;
• captain: Jefri on the current profile;
• sailing since the mid-1990s.

The vessel offers a more intimate group size.

A smaller capacity can improve personal interaction but does not mean cabins are large.

Traveller reviews mention compact cabin spaces.

Guest needs to inspect:

• stairs;
• deck;
• cabin access;
• bathroom;
• motion;
• noise;
• and medical suitability.

The website says Katharina was built in Kalimantan and adapted for expedition cruising.

Current ownership and registration need vessel documents.

Traditional pinisi and UNESCO wording

SeaTrek describes pinisi as a UNESCO-recognised tradition.

The distinction is important.

UNESCO recognition applies to the art of boatbuilding in South Sulawesi and related cultural knowledge, not to an automatic certification of each commercial vessel.

The brand should not imply UNESCO has certified:

• Ombak Putih;
• Katharina;
• SeaTrek;
• or cruise safety.

The ships can embody the recognised tradition.

Vessel construction, conversion, current maintenance and passenger certification still require maritime evidence.

Cultural heritage should be credited to Konjo, Bugis and related boatbuilding communities.

Expedition cruises

SeaTrek’s scheduled cruises explore routes across eastern Indonesia.

The site lists products such as:

• Raja Ampat;
• Komodo;
• Spice Islands;
• Wallace-related routes;
• whale-shark journeys;
• rare routes;
• family expeditions;
• and cultural journeys.

Cruise length can range from around one to more than two weeks.

Itinerary is not guaranteed.

Booking terms state that weather, currents, harbour masters and captain decisions can require route changes.

Traveller should treat itinerary as expedition framework, not a fixed port-by-port promise.

Remote travel creates uncertainty and is part of the product.

Schedules

The website has a current schedule page.

A scheduled departure can still be:

• available;
• limited;
• full;
• altered;
• combined;
• or cancelled.

Booking is not final until confirmation is received.

The traveller should not purchase non-refundable connecting flights before confirmation.

Cruise start and end ports can require domestic flights.

The company’s booking terms say it will assist with re-ticketing costs arising from its scheduling changes, but the exact scope should be confirmed.

A schedule page should show last updated date and vessel assignment.

Vessel assignment can change.

Deposit and final payment

Booking terms require:

• 25 percent deposit per person at booking;
• final payment 90 days before departure;
• full payment when booking within 90 days.

Payment can be cash or wire transfer.

Wire booking is confirmed after funds clear.

This is a substantial advance-payment exposure.

Customer needs:

• invoice;
• legal entity;
• bank account;
• booking number;
• vessel;
• cruise;
• and refund terms.

The website terms do not clearly identify the current legal recipient.

Before transferring internationally, traveller should verify beneficiary and intermediary fees.

A broker or travel agent can have different payment protections.

Cancellation by traveller

Current booking terms set cancellation fees:

• more than 90 days before departure: 25 percent;
• 90 to 60 days: 50 percent;
• within 59 days: 100 percent.

The booking can be transferred to an alternate participant at the same fare.

No refund applies to unused portions after the tour begins.

Unreimbursed supplier payments can create a change fee.

Traveller needs to understand:

• whether fare difference applies;
• name-change deadline;
• medical transfer;
• and airline implications.

A transfer of cruise booking does not automatically transfer flights or insurance.

Travel insurance should cover cancellation terms.

Cancellation by SeaTrek

SeaTrek can cancel, alter or modify a trip for safety, comfort, local circumstances or events.

The booking terms also allow moving guests from one boat to another to optimise passenger numbers.

If a rare full cancellation occurs, SeaTrek says it will offer:

• an alternative cruise;
• or a full refund.

The company also says it will assist with re-ticketing costs caused by scheduling changes.

“Assist” needs a written financial limit.

A vessel substitution can materially change:

• group size;
• cabin;
• layout;
• and experience.

Traveller should know whether consent or price adjustment applies.

Charter agreement may have more detailed owner-delivery remedies.

Force majeure

Booking and charter terms contain broad force-majeure clauses.

Examples include:

• storm;
• collision;
• grounding;
• war;
• terrorism;
• fire;
• pandemic;
• government action;
• and major breakdown beyond control.

The charter terms state that shipyard delay or crew change not attributable to force majeure is not force majeure.

This is a useful limitation.

In a vessel-delivery failure, the charterer can receive:

• pro-rata refund;
• extension;
• deferment;
• or full repayment depending delay and circumstances.

The exact signed charter agreement controls.

Customer should ask whether recoverable supplier amounts are returned.

Captain authority

The captain has authority over safety, route and vessel operations.

Charter terms allow the captain to reject an instruction that would be unsafe, illegal or prevent redelivery.

The captain can also exclude a guest from water-activity equipment when the guest:

• behaves unsafely;
• is irresponsible;
• is under alcohol influence;
• or risks other people or property.

This is appropriate maritime governance.

A charterer cannot override safety through payment.

The captain can terminate or change activity subject to the contract.

Traveller should receive safety briefing and respect crew rest.

Health requirements

Booking terms require a medical questionnaire.

SeaTrek notes that trips vary in fitness demand and that medical care beyond basic first aid may not be immediately available.

Guests must disclose physical, dietary or other conditions requiring attention.

Remote areas can have long evacuation times.

Traveller should consider:

• mobility;
• stairs;
• heat;
• boat motion;
• snorkelling;
• trekking;
• and medication.

SeaTrek says it assumes no responsibility for medical care provided.

This clause does not remove duties imposed by law, but it highlights the need for independent medical preparation.

A doctor should be consulted where relevant.

Mandatory travel and medical insurance

The cruise price does not include travel insurance.

Booking terms strongly encourage trip cancellation and interruption coverage and mandate a travel and medical policy with emergency evacuation coverage.

Charter terms also say the charterer should carry personal-effects, medical, accident and emergency-evacuation insurance.

Traveller must verify:

• destination;
• vessel;
• snorkelling;
• trekking;
• wildlife;
• pre-existing condition;
• evacuation limit;
• and cancellation coverage.

A standard credit-card policy may be insufficient.

The insurer should cover remote Indonesian waters.

SeaTrek should collect proof and explain minimum limits.

Vessel insurance

Charter terms require the OWNER to insure the vessel with first-class insurers for customary risks, charter permission, third-party liability, tenders and water-activity equipment.

The terms also require crew injury or liability cover, and extensions for war, strikes and pollution.

Copies of relevant insurance documents should be available on request and carried onboard.

This is a strong contractual provision.

The profile did not inspect current certificates.

Traveller or charterer should request:

• insurer;
• policy;
• vessel;
• period;
• limits;
• deductible;
• and charter permission.

The legal owner named on the policy should match the charter agreement.

Safety and seaworthiness

Charter terms require the OWNER to deliver the vessel in:

• full working order;
• seaworthy;
• clean;
• properly equipped;
• and ready for service.

The vessel should carry equipment required by its registration authority.

The owner should provide a captain qualified under flag-state requirements and acceptable to insurers, plus a trained crew.

These are contractual commitments.

Independent evidence should include:

• registration;
• passenger certificate;
• safety-equipment inspection;
• radio;
• fire;
• life rafts;
• maintenance;
• and crew qualifications.

A published term is not proof of current compliance.

Charterer should request documents before final payment.

Children

SeaTrek markets family adventures.

Charter terms state the charterer is responsible for children’s conduct and entertainment, and crew are not responsible for entertaining them.

This does not remove normal safety duties.

Parents need to inspect:

• railings;
• stairs;
• cabin;
• tender transfer;
• life jacket;
• snorkelling;
• and supervision.

Child-size safety equipment must be confirmed.

A remote expedition may not suit infants, young children or certain medical needs.

Other guests can also be affected by family arrangements.

Private charter may offer more control.

Snorkelling and water activities

Snorkelling is a core SeaTrek experience.

Charter fee includes snorkelling gear and sea canoes according to current terms.

Guest should verify:

• gear fit;
• life jacket;
• buddy system;
• current;
• reef;
• tender;
• guide;
• and emergency.

Snorkelling is not risk-free.

Strong current, panic, equipment failure and health events can occur.

The captain or guide should cancel activity when conditions are unsuitable.

Wildlife sightings are not guaranteed.

Guests should not touch coral, feed wildlife or disturb animals unless an ethical programme explicitly permits a controlled activity.

Land excursions

SeaTrek expeditions include village visits, trekking, waterfalls, cultural events and other shore activities.

Land excursions can involve:

• tender landing;
• uneven terrain;
• heat;
• local transport;
• and community rules.

Charter terms include excursions and an English-speaking tour leader in the fee, but some extraordinary shoreside transport can be charged separately.

Traveller should inspect exact inclusion.

Local guides can provide expertise and economic benefit.

Community visits need consent and respectful photography.

A visit should not interrupt ritual, school or daily life.

Expert-led and Rare Routes

Select departures include coral specialists, marine biologists, naturalists or cultural experts.

Expert participation can deepen interpretation.

The customer should know:

• expert name;
• qualification;
• role;
• lecture;
• field activity;
• and substitution.

An expert can become unavailable.

The cruise should state whether departure still operates and whether compensation applies.

Scientific discussion is not a medical or safety service.

Citizen-science activity needs data quality, ethics and partner governance.

Rare Routes are limited departures and can have greater logistical uncertainty.

Charters

SeaTrek offers private charters using existing or custom itineraries.

Charter contracts are more complex than per-person bookings.

The current terms cover:

• vessel delivery;
• cruising area;
• guest limit;
• captain authority;
• crew;
• operating costs;
• insurance;
• complaints;
• force majeure;
• and arbitration.

The charterer needs page-one particulars naming:

• OWNER;
• Broker;
• vessel;
• dates;
• port;
• fee;
• bank;
• and guest number.

Do not sign a generic web template without completed particulars.

Advance Provisioning Allowance may apply depending the agreement.

A custom route must remain legal and safe.

Operating costs

Charter fee includes:

• vessel and equipment;
• crew;
• basic stores;
• linen;
• waste disposal;
• crew food;
• vessel and crew insurance;
• full-board meals;
• non-alcoholic beverages;
• excursions;
• towels;
• limited laundry;
• snorkelling gear;
• sea canoes;
• English-speaking tour leader;
• and airport transfer outside Bali according to current clause wording.

Extra costs can include:

• additional running hours outside itinerary;
• shoreside transport;
• customs formalities;
• excessive laundry;
• special equipment;
• domestic airfares;
• gratuities;
• alcoholic beverages;
• and extraordinary expenses.

Credit-card payment for onboard extras can carry 2.5 percent surcharge.

Charterer should request a sample budget.

Complaints

Charter terms require complaint notice first to the tour leader and captain.

If unresolved, notice should go to owner or broker within 24 hours where practical.

This is a short deadline.

Guest should document:

• time;
• event;
• photo;
• witness;
• and requested remedy.

Remote communication can be unavailable.

The clause recognises that exception.

The company should provide a post-trip complaint channel for issues that are discovered later.

A twenty-four-hour operational notice should not remove statutory consumer rights.

Scheduled-cruise complaint terms are less detailed on the public page.

Sailing for Good

SeaTrek launched Sailing for Good in 2025.

The homepage reports activities such as:

• coral and mangrove planting;
• community libraries;
• swimming goggles;
• water filters;
• school books;
• and carbon offset.

The current page displays numerical impact claims.

One figure appears as “150 K Tons CO₂ offset”, which may be a formatting or unit issue and requires clarification.

Impact numbers need:

• period;
• method;
• partner;
• location;
• survival;
• beneficiary;
• and verification.

Coral planting should measure survival and ecological appropriateness.

Carbon offset should identify standard, project and retirement evidence.

Community partnership should avoid charity tourism.

Awards and partnerships

The timeline lists:

• WWF Signing Blue relationship;
• Magellan Award;
• Tripadvisor awards;
• and Azure Road Impact Award 2026.

Awards and programme memberships are dated reputation signals.

They do not certify vessel safety or legal compliance.

The WWF relationship appears historical from 2017 and current status should be checked.

The Azure Road award is current 2026 according to company and award reporting.

UKMS should map each award separately.

Do not apply award to both vessels or every future cruise without scope.

Privacy

SeaTrek’s Website Terms contain a short privacy section.

It promises to:

• identify collection purposes;
• limit use;
• retain data only as needed;
• collect legally;
• maintain accuracy;
• and protect against loss or unauthorised access.

This is principle-based but incomplete for 2026.

SeaTrek can process:

• identity;
• passport;
• medical questionnaire;
• dietary information;
• insurance;
• booking;
• payment;
• emergency contact;
• photo;
• and travel history.

Medical and insurance data are sensitive.

A modern privacy notice should identify:

• legal controller;
• processors;
• hosting;
• countries;
• retention;
• rights;
• deletion;
• marketing;
• and incident contact.

Website terms use old or awkward template wording, which reduces clarity.

Payment and fraud

SeaTrek accepts wire transfer and cash under its terms.

An international traveller should verify:

• beneficiary name;
• bank country;
• currency;
• invoice;
• broker;
• owner;
• and payment schedule.

Never rely on an emailed bank change without callback verification.

Travel companies and yacht charters are frequent targets of business-email compromise.

The current website does not publish a legal entity beside the bank process.

This makes verification essential.

The charter agreement should name the account and owner.

A broker should explain whether funds are held, transferred or protected.

Legal entity uncertainty

Current official pages use SeaTrek Sailing Adventures as brand but do not display a PT or other legal name.

Historical third-party sources mention PT Ombak Putih.

The ship Ombak Putih also shares the name, which can create entity confusion.

Possible current structures include:

• vessel-owning companies;
• management company;
• travel company;
• and broker.

UKMS does not infer the current structure.

The final page should request:

• corporate registry;
• vessel registry;
• owner;
• operator;
• broker;
• insurance;
• tourism licence;
• and maritime licences.

Each charter can name a different OWNER.

Current activity

SeaTrek’s website was active on 31 July 2026.

New articles were published on 27 July 2026.

Cruise schedules, vessels, terms, charters, experts and conservation pages were current.

Copyright showed 2026.

Current reviews and 2026 award references were present.

These are strong activity signals.

They do not prove current legal entity, every vessel certificate, financial condition, accident history or independent impact metrics.

Questions before booking or chartering

1. What legal entity is the operator or broker?
2. Who owns Ombak Putih and Katharina?
3. Which entity appears on the invoice and bank account?
4. Which vessel is assigned and can it be substituted?
5. What registration, passenger and safety certificates apply?
6. What vessel and crew insurance is current?
7. What travel and evacuation insurance must the guest buy?
8. What cancellation and force-majeure rules apply?
9. What health and mobility requirements apply?
10. What itinerary changes can the captain make?
11. How are medical, passport, insurance and photo data processed?
12. What independent evidence supports conservation and carbon claims?

Decision summary

SeaTrek Sailing Adventures is a distinctive Indonesian expedition-cruise brand with two established pinisi vessels and detailed public booking and charter terms.

Its strengths are small-group format, local crew, remote routes, cultural interpretation, current activity and contract transparency.

Its main diligence risk is legal-entity and vessel-owner clarity.

The brand should not be published as the owner of both vessels until current registry and charter documents are reviewed.

SeaTrek is not classified as an UMKM. Its more accurate position is a long-running Indonesian marine expedition and small-ship cruise operator.
