A Photo & Discussion Forum for Wharram Design Enthusiasts
I think you have the right idea. Have you seen the photo series on UNloading an 8M on the Wharram site?
There's more info, starting here: http://www.wharram.com/forum/viewtopic.php?f=3&t=142&p=637&...
Is this the boat from Staten Island?
How far do you have to go? We did something similar to what you describe when we sold my Tiki 30 (We're now building a Tiki 46 - god help us ). BUT - if you have enough manpower, your proposed solution will definitely work. The trick with the cradle with wheels is to find the 'sweet spot', where the hull will balance with a minimum of babysitting. We used my beefy nephews as counterweights fore and aft on the hulls to balance them on dollies. At any rate, one of the fun things about the Wharram spirit and KISS principle, is figuring out novel ways to move stuff around with a minimum of modern technology.
We did this with a 30: remove the cockpit tray, replace the beams (one at a time)and replace with 4X4's (lashed loosely enough to allow lateral movement but tight enough to keep the hulls upright), jack the boat off the 6x6's with 2 floor jacks with wheels, PUSH the two hulls together, lash them together, back the trailer up under the bows, send cargo straps under the hulls around the skegs, winch the two-hull unit forward up onto the trailer.
Hope my prose makes the image clear. Sorry, I don't think we took pics of this process.
Remember: it's always fun to devise a clever way to do this stuff, but with enough muscle, beer, food, and music, it's quite easy til you get to the really big boats....

Thanks David. If I'm reading you correctly, I need the proper mixture of optimism, people power, incentive, ingenuity, practical physics, tight fiscal policy, and the spirit of adventure. I'm liking this Wharram family more all the time! Piecing all the helpful advice I've gotten thus far, my current plan is to emulate, as closely as possible, the procedure for disassembly on the water. I want to put the cradles on top of flat dollies with casters (of the furniture moving variety). I'll place these under the hulls around or just aft of the midpoints, then let each one down individually using two floor jacks (of the automotive variety). Then I'll loosen the lashings on one crossbeam and replace it with a loosely-lashed 2x4 and repeat with the other crossbeams (removing the cockpit when appropriate). My lightly inebriated grunts and I will then push/pull the hulls together, tighten the 2x4 lashings and move the trailer as far back under them as possible, (maybe jacking up the tongue a bit?), then chock the wheels. I'll attach the trailer winch cable to the forestay bridle, then ever so slowly winch the hulls forward until there's a little weight on the tongue. Attach the trailer to the truck, and apply proper strapping. Voila! I'll also keep my $300 rainy day money in my pocket for the crane man...just in case.
If the gods smile, I may see you in FL this winter.
