I make cray pots all the time. I made mine 900x800, and the reason i made mine that size is so when carting them in my Surtee's I can stack two beside each other. I make mine out of timber and use cray mesh to cover them. I purchase my plastic pot entrance, feeder ropes and buoys, and cray mesh etc, from Quality Equipment in Hillside Rd Glenfield. I screw my pots together with stainless screws. I also mark my buoys using cattle ear tags, so the name doesn't come off and is held on using an electrical tie. Concrete curbstones (2 x 70mm wide one's )
are used to anchor it to to bottom. I have a cray davit to lift the pot,s so I don't scratch the boat and every Xmas for two weeks, I get between 15 to 20 cray,s using 4 pots on average. Two are mine and two are my sons, I have 6 all told, and the reason I only put out 4 is that cray's are so rich you easily get sick of them, and I give half of them away. About to make more for my son in law who keeps asking for me to make him some.
When the going gets tough...the tough
