Now you're talkin', Damon! Well if the weight of the Mystere, Prindle, ARC-Supercat, and Hobies have got you down, then I suggest the M20 and the T5.7.
The Marstrom 20 is about 9 feet wide, I think. Maybe you could trailer it around without being too intrusive. A bit pricey, but it seems to me to be the ultimate single hander for a large man.
More practical would be a Taipan 5.7. Now we know that the T4.9 is a hot boat and our own Rick White seems to prefer it. But I'll bet that he'd say, especially since he has one for sale, that he'd want to be on the larger 5.7 if he was a much heavier guy.
I think that if I lived near Rick, that that Taipan 5.7 would probably have been in my posession years ago.
The thought of a 'less than 300 pound' boat of this size is dreamy. Tossing it around, on and off the trailer would be a cinch. Brings thoughts to me of a guy that was seen in my neighborhood who used to get under his Hobie 17 on the launch ramp, lift it on his shoulders, and rotate it 180ยบ before setting it in the water.
