I got a lightly used Hobie Compass and began outfitting it. Installed a garmin stryker 4 fish finder, jerry rigged the transducer to its Lowrance mount and routed the wirings and battery to the inside.
Bought on Etsy a 3d printed mount for the fish finder and installed map pockets on the sides. Made the drive leash from net lanyard.
A handle was added for something to grip on to load and unload. At 68lb it’s pretty manageable by myself. Also glued on keel guard.
In terms of safety, I made a light/flag pole out of pvc tubing. Bought a orange NRS Raku pfd, bet I’m the brightest thing there is out there
