This Space Cadet is a great boat, but not for someone 63. Check out the Pyranha S6F 192 or 193. It was new this past year & it has a lot of room for someone your height. I also agree with all of the Kingpin fans out there; have a look at that boat, but be prepared to drop some cash for both. Jackson also make a boat for someone your size, but I don't think you will find it for sale on a used forum any time soon. Less expensive options are the Pyranha S6 200 or the big version of the Dagger G-Ride. Both are great boats & IMHO have some leg room, are kind to folks on the learning curve, and fit into the "modern" boat category. Keep in mind that the longer a boat has been on the market, the more critics (and fans) it has. That can be good and bad, so just find something that fits and learn to paddle it.
Thats my $0.02 & I understand if you want your money back. BTW, inseam in addition to the personal info you provided is always helpful. Not all folks "bend" in the same place...
Try not. Do, or do not. There is no try.
