Alubat OVNI 370, what a lifting centreboard changes.

Published 4 November 2026 · WHV

Alubat publishes two draught figures for the OVNI 370. With the centreboard raised, the builder lists 0.92 metres. With it down, the figure is 3.08 metres. That difference is a good way into the boat’s design. A shallow approach and sailing to windward call for different things from the same hull.

Put those figures beside the charts and tidal information for places you sail. A shallower configuration can change where you start looking for access, but conditions, local limits and the rest of the boat still govern the decision. The mechanism that makes the change possible deserves attention in its own right.

Ask a surveyor to inspect the board mechanism, access for maintenance and the corrosion protection of a specific hull. Ask the yard how the board is serviced and which work can be carried out locally. The practical value depends on the route you sail and the boat you can actually maintain.
