SUP is done! Now I have the scary task of cutting into it for the round hatch I bought for it (5 inch I think). I am going to go with that over the breather tube. Read posts on this some time back. Have seen it installed on several of them pictured and would like to install one.
One thing I want to make sure of is that I cut the hole in the right spot without hitting a support. Anyone know if that dimenson?
