Carl,
Just conjecture here as I've not worked it out, but I worry about stability with that, perhaps reversing the cg, and center of buoyancy (bad news).
Anecdotal evidence (as demonstrated by the nice folks at "hydrohoist"), suggests the hydrohoist on wheels concept may very well be viable. The tires, may or may not have to to compensated for.

Joe,What about a inflatable float design, basically an underbelly or below the waterline bladder?Carl D.----- Original Message -----From: Joseph PerkelSent: Sunday, November 05, 2006 6:12 AMSubject: Re: [PSUBS-MAILIST] Launch Retrieval Transport
Did a quick and dirty conceptual sketch of the "dry dock / utility trailer".
(not to scale),
(Cylinders are MBT's and rectangles are floats.)

What you have here, is basically a "hydrohoist" on wheels.......

However, not yet solved, are the proper volumes / dimensions of the
components and how it all fits to scale, with wheel height, width, cg and
center of buoyancy all worked out.
As Jay points out, this is unsuitable for towing to sea, and remains only a
potential for "skinny water" launching, but it does have the advantage of
not having to worry about "clearing" the trailer in any given distance from
the launch vehicle.
