I slightly modified a 12'11" by 6'8" Conrad design. ( Coming from someone who normally fished our of fiberglass 20+ft boats this was going to be a compromise or so I thought...
Ended up very pleased overall. This boat had to be light at 1/8". Very dry and super stable. Handles chop well, and In bigger stuff it doesn't submarine or do anything funny it almost feels easier to drive in rough stuff because it can plane at 14mph. Overall it feels very strong.
Could easily make it self bailing, this one is not.
Elec downriggers, 9inch touch screen im lazy and a poor fisherman so i need every edge i can get.
A 40hp would be fun. But it will do 27mph 1 person with the 30hp. 40 or 50hp next yr once someone buys the 2019 suzuki off me it's too light.
Would be expensive to build this hull, I don't know what someone would charge but over 15-20k I bet rigged out. Ways to make it cheaper, this was a 1st kick at the can. Aluminum alone was 5k to have cut and formed (including plate).
I imagine a 16ft version would be a very capable boat. I'd always recommend tiller hard to beat the control over the vessel.
