Ramform vs SWATH for seakeeping?

Seen at least one picture that made a houseboat look like a cave.

A Death Star floating home with ramform hulled Star Destroyer tender would be fun but peg one as a serious, serious fanboy. Unfortunately Disney has no sense of humor and their lawyers can beat up anyone's lawyers....

 

I've made a sketchup conceptual model along similar lines:

Flying saucer houseboat https://3dwarehouse.sketchup.com/model/e575b6d2-3cf5-4395-a828-f03cb078a8fe/Flying-saucer-houseboat

 

Barge + tug is certainly an appealing design! A small "pusher" boat could also work as a re-supply vessel. I assume that a barge would roll and heave uncomfortably in storm though. As I understand it, the larger the barge the less subject it is to heave/pitch/roll motions. Any idea how I to go about determining the size of barge that would be comfortable even in 8 ft waves?

 

Thanks for your response, Gonzo!

When you say a good stabilizer system, are you referring to something like this?

If not, what did you have in mind?

If you were to build a houseboat that needed to move once every 30 days, and would be periodically subject to 8 foot waves, would you go with a barge?

"Otherwise, if the water will be really shallow (under 30 feet) a lift boat, as suggested earlier is the cheapest and simplest solution."

I agree, a self elevating houseboat seems like a reasonable idea. But although I've seen many examples of houses on stilts, and commercial liftboats, there don't seem to be many houseboats on lifts. If you happen to know of one, I'd love to see it!

 

Those active stabilizers (gyroscopic) work really well. They do require a power supply though. I haven't seen a houseboat on lifts, but people working of barges live aboard.

 

Been a long while since I've been on this forum. A couple of years ago I worked up a Ramform idea, even emailed with people at PGS and Mauro Skully (worked on the design that was almost built for some rich somebody, that made news). Idea isn't to motor around in it, so much as go out park it at a permanent mooring and live there. Yank the engines out of the water, rinse and store them in lockers, to prevent unnecessary fouling and corrosion, that sort of thing, then deploy water turbines to generate some electricity. Goal is more of a liveaboard without shore-ties, monitoring and working an IMTA (Integrated Multi-Trophic Aquaculture) 'farm', with kelp, feeder-fish, marketable fish, shellfish, Abalone, that sort of thing. Feed kelp to feeder fish, on up the food chain, do so with minimal inputs from shore-based sources...

Initial design is a 'yacht' for 2. Telescoping marker-mast, use currents to maintain a stable orientation, and so forth. All the calculations are based off the known patents by Roar Ramde, for the Ramform Vessels built and operated by PGS, as well as the one sold to Japan... Even placement of the bed is based on the most stable point inside the hull. Needs some additional work, but, other than a lift from the lower deck to the control cabin, the design is also fairly ADA accessible.

If possible, I'd like to find someone to design the hull for Ferrocement, for me.
