Serangan Boat Yard: Access, Draft and Hardstand Considerations

Written and maintained by the Bali Shipyard Build Desk · last reviewed 19 August 2026

What Serangan does well

The trade base here is practical rather than industrial. Timber work, GRP repair, outboard service, small-craft fabrication and the general business of keeping a working fleet running are all routinely available, and the turnaround culture suits boats that earn their living daily and cannot sit idle.

Typical vessels that fit naturally:

• Dive boats and day boats operating to Nusa Penida, Lembongan and the east coast.
• Fast boats on the inter-island runs.
• Traditional timber craft and working boats.
• Tenders, RIBs and small motor craft.
• Smaller sailing and motor yachts within the draft limit.

The draft question

This is the first and often the last question. The approaches around Serangan are shallow in places, and the usable depth changes with tide state and with the specific route taken. What that means in practice:

• Loaded draft, not brochure draft. The figure that matters includes fuel, water, gear and crew.
• The window may be short. A tidal approach can be a matter of hours, and the lift or grounding operation has to fit inside it with margin.
• Spring and neap tides differ materially. A marginal vessel may only be able to move on springs.
• Local knowledge is not optional. Charted depths and actual depths diverge in shifting shallow areas; a local pilot or an escort is worth the cost on a first visit.

Hardstand and shoring in a small-craft yard

Support arrangements here are frequently timber shoring and improvised cradles rather than engineered steel stands — which is entirely appropriate for the vessels involved and requires attention for anything heavier.

Vessel	Typical support	Point to check
Light dive or day boat	Timber blocks and side props.	Ground bearing on sand; props re-checked after rain.
Traditional timber hull	Cradle or extended shoring along the keel.	Even support to prevent hogging; drying and seam take-up.
Small GRP yacht	Keel blocks plus adjustable stands.	Blocks under structure, not unsupported panel.
Heavier vessel	Engineered stands and load-spread	Whether the ground and the stands are genuinely rated.

The general principles of blocking, including what long stays do to a hull, are on Bali slipway and hardstand.

Practical planning for a Serangan job

1. Confirm the tide window and the route before setting a date, and set the lift for the first half of the window.
2. Keep the scope appropriate. This cluster suits straightforward work done quickly. A full fairing and topside coating programme belongs somewhere with containment and controlled conditions.
3. Bring parts with you. Trade availability is good for common items; specialist components are easier to source from the main precinct or by import.
4. Plan for weather. Open hardstands with limited cover mean the wet season affects work more directly here than at a facility with sheds.
5. Agree security and access hours in advance, particularly if you are leaving the boat between visits.

Timber hulls and the drying problem

Serangan sees a lot of timber, and timber ashore behaves differently from GRP. A wooden hull dries, seams open, and fastenings loosen as the planking shrinks. Two consequences follow:

• Do not leave a timber hull ashore longer than the job requires without a plan for keeping it damp or accepting take-up time after launch.
• Budget take-up time. A timber vessel returning to the water usually weeps until the planking swells. That is normal, it must be watched, and the boat should not be left unattended during it.

Timber repair itself — plank, frame and fastening work — is scoped in stages with a genuine discovery allowance, because the extent cannot be seen from outside. That method is described in how boat repair in Bali works.

Serangan versus the main precinct

	Serangan cluster	Benoa precinct
Best for	Small craft, timber, quick turnaround	Multi-trade jobs, larger vessels
Access	Shallow, tide-dependent	Deeper, but commercially busy
Trade depth	Practical and fast	Broad and specialised
Controlled conditions	Limited	Better availability
Cost profile	Generally lower	Higher, with less waiting

Planning a tidal arrival, step by step

1. Confirm the vessel’s loaded draft in the condition she will actually arrive in, including trim.
2. Establish the controlling depth on the intended route, not on the chart’s general figure.
3. Choose the tide. Springs give more water than neaps; a marginal vessel may only move on springs.
4. Set arrival for the first half of the rising window, so a delay is absorbed by rising water rather than punished by falling water.
5. Confirm the lift is ready before the vessel commits to the approach. Arriving on the tide to find the lift occupied is the worst outcome available.
6. Have an abort plan. Where the vessel waits, and for how long, if the window closes.

What to prepare before the boat arrives

• Sling or shoring positions marked on the hull, and a general arrangement available.
• Tanks at the intended state, since fuel and water materially change both draft and lift weight.
• Loose gear secured or landed, and anything valuable removed before the yard period.
• Parts on site, particularly outboard and engine service items, which are quick to fit and slow to source.
• Agreement on where the boat sits, for how long, and who checks the shoring after rain.

Support and blocking principles for a stay of any length are on Bali slipway and hardstand.
