Aluminum Diving Landing Craft Design

I’m looking for a qualified naval architect to turn my concept for a small aluminum landing craft into a full set of build-ready plans. The vessel’s day-to-day role will be commercial diving, so an uncluttered working deck, stability at low speed, and an easily deployable bow ramp are essential. Between dives it will also shuttle freshly caught seafood in various deck tote storage containers, so tie-up points needed, and trim at load considered. Needs back space to seat three crew, including the operator.
-27-29 foot length range
-9.6 - 10.5 foot beam
-17 degree dead rise
-gentle reverse chines
- aft console with a window, large curved roof spanning across the with both the boat.
- twin outboard 150 - 200 hp range (25”shafts)
- top light ship speed - not an objective, 30-35 mph range sufficient. Loaded working speed needs to be in 20 mph range.
- minimum 5000 lbs cargo capacity
- minimum 75 gallons fuel cell
- side dive door
- twin midship davits - 500 lbs lift capacity
- front drop down gate, consider driving visibility

Here’s what I need from you:
• A complete design package: general arrangement, hull lines, structural drawings, scantling schedule, weight estimate, and hydrostatic/stability calculations.
• Material, welding, and outfitting specs that a metal boatyard can follow without guesswork.
• Brief operational notes covering deck loading limits, dive compressor location, and recommended tankage to keep trim neutral when the seafood load varies.

Aluminum workboat experience is a plus, and I’ll favor designers who can show previous landing craft or dive platform projects built to class or ISO 12215. Once I approve the concept sketches we’ll move to detailed drawings and calculations in stages, with clear review points before each release.

If this sounds like your field, let me know what software you’ll use (Rhino, AutoCAD, Maxsurf, Orca3D, etc - ready CAD FILES PREFERRED. Share one comparable project you’ve completed. I’m ready to start as soon as we align on the workplan and timeline.
