Keep it simple stupid...
I have PVC hoop rack that fits over my Hobie bait tank that I use when I'm crabbing and fishing and it works great...but I saw a very simple design when I took some photos of Tony and George launching their PA's last week for some Lobster hooping.
It looked like they used 3/4" EMT conduit because of the flair out that the pipe has at the junction, and it looked like it fit perfect in the rear scupper holes.
It looked so simple I had to try one...
I used regular PVC and fittings although I used the black washers from a 3/4" compression fitting to cushion the contact point on the PA.
I used an 18" piece of 1" PVC pipe and then fittings to reduce to a 6" long piece of 3/4"PVC pipe.
Thanks Guys it works great...!
