Im building a new deck for my boat. Its 6'x6' and im trying to figure out the best wat to attach it to my boat. my old deck i welded out of steels and bolted it through the railing but that was with angle iron. I have a bunch of 1 3/4" aluminum tubing im welding this time around. Just curious how you guys attach it and if you have any ideas. I dont want to put any new holes in boat. thanks guys!!
