Custom Boat Build in Lombok — Concept to Handover

A Lombok custom boat build runs from concept brief, through naval architecture and specification freeze, into structured construction milestones and sea trial before handover. You provide the operational concept, budget band and decision approvals; the yard provides drawings, scantlings, material procurement, Kemenhub documentation support and build supervision, following a defined change-order and payment process agreed in the construction contract.

How a Bespoke Build in Lombok Starts

The starting point for any bespoke boat build in Lombok is a clear operational brief and a realistic budget band. At this stage nothing is cut or laminated; all thinking is on paper and screen.

Use case: day charter, liveaboard, private cruising, dive operations, inter-island passenger, workboat or support vessel.
Operating area: sheltered bays around Lombok and Bali, Lombok–Labuan Bajo line, or more exposed crossings with higher swell and seasonal wind.
Capacity envelope: crew berths, guest cabins, day guests or passenger count, cargo deck area and weight.
Speed and range: target service speed, maximum speed band, endurance between fuel stops.
Regulatory frame: Indonesian domestic passenger, cargo or special-service vessel under Kemenhub and Syahbandar.

At inquiry, the yard will usually respond with an indicative layout suggestion, material options and a planning budget band, then refine this into a structured quotation using the framework described on the price and quotation guide.

Defining the Design Brief and General Arrangement

Once there is alignment on use case and budget band, the next step is design development. This is where a custom boat builder in Lombok will formalise your concept into drawings and a buildable specification.

Design Inputs You Provide

Preferred hull material and style (for example phinisi-inspired, modern displacement, planing monohull, catamaran), later refined using the yard’s hull materials comparison.
Cabin count, bed types, wet areas, galley size and whether crew spaces are separate from guest spaces.
Deck functions: sun deck, dive deck, tender storage, jet-ski rails, boarding platforms, bar and dining areas.
Machinery philosophy: twin or single main engines, shaft line or sterndrive, bow thruster, stabilisation concept.
Interior level: robust charter finish, higher-touch private yacht finish, or commercial workboat simplicity.

What the Yard Delivers at This Stage

Preliminary general arrangement (GA) drawing: plan views of each deck, longitudinal section, basic tank plan.
Principal dimensions: length overall, length on waterline, beam, draft band, estimated displacement range.
Initial weight and stability assumptions, sufficient for Kemenhub route planning discussions.
Outline systems concept: fuel and freshwater tankage, black/grey water routing, generator capacity, HVAC concept.

This is an iterative stage. Drawings are adjusted until traffic flow, cabin count, crew operations and machinery space access all work for your intended operation and maintenance plan.

Freezing the Specification and Contracting

After GA approval, the project moves toward specification freeze and formal contracting with PT Komodo Galangan Nusantara for new build boat Lombok projects.

Specification Freeze

Specification freeze is the point where the technical list is locked for contract purposes. It will normally cover:

Hull, deck and superstructure material and construction method (for example solid timber keel with laminated frames, or GRP sandwich with defined laminate schedule).
Main engines, gearboxes, propellers, generators and key auxiliary equipment by make or at least by power/size band.
Steering system, shafts, rudders, bearings and thrusters including material and diameter bands.
Tank capacities and approximate locations for fuel, freshwater and waste.
Electrical system voltage, inverter/charger concept, battery chemistry and capacity band.
Cabin, galley and head fit-out level including materials and hardware ranges.
Navigation, communication and safety equipment framework to meet Kemenhub and Syahbandar expectations for the intended service.

Contract, Payment and Supervision Framework

The construction contract defines payment milestones, inspection rights, supervision arrangements and how variations are handled. These follow the principles outlined in the yard’s contract, payment and supervision overview.

Typically, the contract is issued by PT Komodo Galangan Nusantara, with annexes for technical specification, drawings list, build schedule and documentation responsibilities for items such as Surat Ukur, Gross Akte and Pas Besar.

What You Supply vs What the Yard Supplies

Responsibility split is important in any bespoke boat build Lombok project. The table below indicates how responsibilities are usually divided; specific projects may adjust this balance in the contract.

Item / Scope	Normally Supplied by Owner	Normally Supplied by Yard
Operational brief and business model	Yes	Advises on feasibility
Naval architecture and structural design	Reviews and approves	Yes, or via appointed designer
Regulatory route selection (domestic trade area)	Preferred routes and ports	Aligns design to Kemenhub frame
Main machinery brand preferences	States preference or restrictions	Proposes options and sources
Interior design direction	Style, colours, reference images	Drawings, joinery, execution
Loose furniture, décor and small equipment	Often yes (owner supply)	Can be included if requested
Dive gear, toys, special equipment	Yes	Provides interface points and storage
Class / surveyor engagement if required	Confirms requirement and budget	Coordinates day-to-day with surveyor
Government fees (IDR)	Yes, paid directly or via escrow	Assists with documentation pack
Onboard crew recruitment and training	Yes, often via PT Komodo Vessel Management	Provides technical handover and manuals

Differentiating between owner-supplied and yard-supplied items early avoids late-stage uncertainty, especially for loose equipment and highly branded machinery.

Build Stages, Timeline and Decision Points

Every pesan kapal custom Lombok project passes through a set of physical build stages and associated approvals. Timeline bands depend on length, material and regulatory complexity, but the decision points follow a consistent structure.

Typical Physical Stages

Keel laying / mould preparation: timber keel setting or GRP mould preparation; baseline alignment confirmed.
Hull structure: frames, ribs, bulkheads and planking or laminate schedule to sheer line, with interim surveys if required.
Deck and superstructure: deck beams, main deck, cabin structures and wheelhouse, with penetration planning for systems.
Machinery installation: engine beds, shaft alignment, exhaust routing, tanks and major piping runs.
Systems fit-out: electrical cabling, switchboards, plumbing, HVAC, navigation and communication equipment.
Interior and joinery: cabins, heads, galley, lining, flooring, doors, hardware and built-in furniture.
Painting and coatings: hull fairing, antifouling, topside coatings, non-skid deck treatments.
Harbour tests and sea trials: systems commissioning, speed trials, manoeuvring and safety drills.

Key Owner Decision Points

Approval of final GA and specification freeze before major material orders.
Sign-off on structural plan before hull closure, especially watertight bulkheads and tank layout.
Machinery and equipment confirmation before procurement to avoid brand or model changes mid-build.
Interior materials and colour selections before joinery production.
Exterior colour and branding decisions before final painting and graphics.

An outline schedule for these stages is normally provided at contracting, then tracked against the framework similar to that in the yard’s build process timeline.

Managing Variations and Change Orders

Changes after specification freeze are common in custom work but must be managed clearly. Each change order should state:

Description of the requested change, referencing the original drawing or specification clause.
Impact on price (increase or decrease) within a USD band and payment timing for the variation.
Impact on timeline in weeks, if any, including knock-on effects for later stages.
Drawings or sketches showing the updated arrangement or system routing.

Agreed change orders are then added as contract annexes and reflected in updated drawings so the build team on the ground is always working from current information.

Trials, Documentation and Handover

Before delivery, the vessel must prove its systems and performance, and the documentation must be in place for legal operation in Indonesia.

Harbour and quay tests: electrical load tests, pump capacities, steering, windlass and bow thruster checks, bilge system tests.
Sea trials: speed runs at various RPM bands, crash stop tests, turning circles and noise/vibration observations.
Safety and lifesaving gear: inventory check against the agreed specification and Kemenhub requirements for the intended passenger or cargo category.
Documentation pack: drawings set, equipment manuals, wiring and piping schematics, recommended maintenance schedule and basic operating procedures.
Regulatory filings: assistance collating the technical documents used by the owner or their agent to arrange survey, Surat Ukur, Gross Akte and Pas Besar through Syahbandar.

At handover, physical inspection and sea trial sign-off are normally combined with a snag list, with any remaining items tracked to completion under the terms of the construction contract.

Frequently Asked Questions

Can I bring my own naval architect's drawings?

Yes. The desk reviews the drawings for buildability with the selected yard — materials, scantlings, equipment availability, slipway limits — then converts them into a specification schedule and milestone plan that a Lombok yard can execute and an inspector can verify. Owner-supplied designs are a normal starting point, not an exception.

How custom can a Lombok build actually get?

Hull form, layout, tankage, engine brand, electronics and finish level are all open. The practical limits are slipway and launch size at the chosen harbour and lead times on imported equipment. Where a concept outgrows what local ways can launch, the desk says so at the brief stage and routes the project to specialist partner facilities.

What deposit does a custom build require?

There is no single large upfront payment. The contract sets staged milestones from signature, and each release follows inspected progress under the supervision terms — the structure detailed on the contract and milestone page. Early exposure is limited to design and mobilisation stages.

Who owns the design at the end?

The owner. Drawings, the specification schedule, equipment manuals and the certificate file are all part of the handover pack. The boat’s documentation is treated as part of the vessel — it transfers with the boat, not with the yard.
