The Siam 25 has been drawn up as a open dive and fishing boat for a client in the far East that can also be used for simple family trips around the islands. Her hull has been based on the Rathlin 20' motor launch hull - a robust and stable design. The design is very adaptable - some will want to remove the rig completely and others may just fit the mizzen as a steadying sail. The hull will also take more extensive accommodation.
Details for both an outboard well and for an inboard engine installation have been included. The cockpit can drain into the outboard well.
Construction is Western Red Cedar strip ith plywood bulkheads - the bulkheads may be set up on the building jig and used as moulds.
The accommodation drawn is a simple open arrangement with an open backed wheelhouse which accommodates a basic wc compartment and galley. The remaining space is open under a simple awning
