Day dreamers Idea of a Liveaboard/ Island hopper.

Get yourself a Shark catamaran, modernize it, and design a tent structure for camping in it.

The Sharks sail really nice with good load carrying ability.


or try 'shark+catamaran with a tent'
 
Nope, get yourself a 1976 Clipper Marine 32 (Crealock design) that has the giant open motor well in the middle of the rear cabin between the bunks. The lip is about 3" above the waterline if you are lucky, and right beside your head when you are laying down. No watertight compartments in the boat. These things will absolutely cure you of your through-hull problem. They have crossed oceans and survived direct hits from cat 5 hurricanes in the Florida Bay.

 
My Thoughts, As a non-sailor. Food for discusion.

Every design is a compromise.

Design brief. (Addressing Catamaran/trimaran Pros and cons. )

1 - Dimension Max width 2.8meters (When in trailerable mode).
2 - Hulls with no though holes. (maybe fuel tanks, No storage...nothing)
3 - Wave piercing hulls.
4 - Rotating Hulls - yes I let a little crazy out. Hulls can be Rotated at the waterline for Cleaning, antifoul Painting and repairs if needed. Think Zero Haulout!
5 - Metal Hulls (Steal vs Ali fight)
6 - Distance between Hulls can expand and contract. Telescoping.
7 - Bridgedeck Clearance very high (compromise = higher center of balance.
8 - Aft-mast. design. (Pro easy to single sail, furl, no boom, But comes with many cons.)
9 - Electric Propulsion (Motor fitted and submerged in Rudder below the waterline - Passive cooling - Think IP69 motors in extream submerged Industrial applications)
10 - Diesel power generators
11 - Wheels/auto fenders (see pictures) More Crazy can self haul out/beach crawl....Standard Car wheels.
Interesting concept! I like how you’re thinking beyond the usual catamaran/triamaran setup and addressing practical issues like maintenance, beaching, and trailerability. The rotating hull idea is definitely unconventional—I’d be curious to see how the design performs in real-world conditions.
 
A square wheel is also unconventional.
