Chuck Paine is a talented designerJust saw this one pop up, seems to fit the niche. I have no known interest in this thing, so not trying to skirt the classifieds rules, whatever they might be.
Some of your boats look like they would be easy and affordable to build. That one looks like it would fall together with sheet materials. Also looks like it could be very comfortable below and still efficient and good-looking.
ya seems suspect. Prop design is a thoroughly developed field, so making claims of some sort of huge breakthrough in efficiency don't seem realistic. Maybe a few percent under certain circumstances. But the thing about prop design is if you make a gain under certain conditions, then you will lose efficiency under other conditions. It's kinda like the bow bulbs on ships- yes they can reduce a bit of drag in a narrow speed range at a given draft, but in all others it will usually be more drag.I've seen it. I don't pretend to understand how it works in depth (other than "tip vortices bad")
Mobius propellers scare me a bit. View attachment 479228
Testing it against a 14.75x15 and 15x15 is great but were those the best props for the boat? I'm not so sure. Were the conventional props deliberately underpropped? (they all reached top engine RPM) Would a 4 blade been better for getting on plane (probably). The test reads like an advertorial.
A Rib Might be successfulI like ribs.
For example Ukrainian Grant.

OXE 200hp Diesel Outboard | Review| Motor Boat & Yachting - YouTubeDon't know how closely some of you are watching the outboard motor market but it is brutal. Guys have brand new boats with no motors and no idea when they will come in. Year long waiting lists, etc.
I just got notified my new build was imminent (whatever that means), I thought it would be late spring.
A bit of panic as a specific motor needed to be sourced pronto. Called and surfed around with the same result, 'we can put you on a list.' Finally found just the one I wanted, probably the last one in the area.
It's better to be lucky than good.
I do wonder how those IPS drives would fare in my home cruising grounds in Maine. They look like pot warp magnets to me.
We only have "onboard footage", but I'll dig it out.I really want to see that thing at full speed, trisail. Video, preferably, but a pic would do.
