I than used fully sealed rivets (normal rivets have a hole through them) to hold it all together. Its been about 2 years now and it still does not leak.
Honestly though if you wait till the water is flat calm (looks like glass) you can see much better into the water and in a much bigger area than you ever could through a small hole in a boat floor.

Thanks. Most of the milfoil search is done by looking down on calm mornings, using polaroid glasses. That works pretty good down to maybe 10 feet, but there are huge fields of milfoil that are deeper than that. Finding them is the problem. We have used a small tube that is also used for Secchi disk work, but the field of vision is very narrow. I wish my toy budget allowed for an underwater camera. Snorkeling works better, but it is hard to cover a lot of area that way.
You should see the quantity of milfoil being brought up. Just this Monday, the crew harvested over 400 gallons, with over 1500 "root balls". The finders need to stay ahead of the harvesters.
