Boat suspension

This is old hat.

Experimental Catamaran with active X-Y-Z stabilization from "Velodyne Marine" https://www.boatdesign.net/threads/experimental-catamaran-with-active-x-y-z-stabilization-from-velodyne-marine.46493/

 

Thank you for dig it out . Today I found a thread on this forum , Turkish guy wanted to sail from the Black sea to Amsterdam as a barge leech.

 

IMO the key missing term here is "un-sprung weight".

I'd try something more like the Delta Seadart experimental jet fighter with ski(s) and shock absorber.
Make them just skis, not floats, for lighter weight and better sprung to un-sprung ratio.
At rest or lower speed the skis would submerge and provide anti-roll damping.

Maybe tune the size of skis so the hull could still take a bit of wave in tough conditions

 

"un-sprung weight" I know something about it. This is an important phenomenon .
Post no. 3 from 3:10 looks ok. If the buoyancy of the floats were reduced, they would turn into skis. I wonder how to propel a ship on waves on these skis.

 

Basically, that is what the Soviet/Russian Raketa (Project 340) and Voskhod (Design 352) hydrofoils where.

 

They are successful hydrofoil designs but they suffer on the waves .I like their CCCP futuristic look and overall concept.
