Power Catamaran Redesign Plans

I have a proven power-catamaran design that currently runs twin 150–200 hp outboards. For our existing production line I now need a compact version that performs efficiently with two 50 hp outboards. The core task is to resize the hull while preserving the ride, stability, and overall look of the original model.

The boat will be built in fiberglass, so the laminate schedule and all scantlings must be updated accordingly. Once we sign an NDA I will forward the native CAD files (Rhino and DWG), hydrostatic reports, and sea-trial data from the larger craft.

What I expect back:

• Updated lines, offsets, and weight study that demonstrate the correct displacement and trim for the lighter power package
• Complete structural drawings, laminate specifications, and CNC-ready mould geometry in Rhino or compatible formats, plus PDF sheets for the shop floor
• Engine-pod / transom arrangement sized for two 50 hp outboards, including mounting details, fuel and steering runs
• Hydrostatic, stability, and performance predictions that confirm the redesign meets ISO small-craft standards (or an equivalent rule set)

Acceptance: the drawing set must be build-ready—our laminators should be able to cut moulds, order materials, and assemble without further lofting or reverse engineering. If questions arise during construction, I’ll rely on you for prompt clarifications, so please keep your working files organised and traceable.
