Bill why not just get a sea doo sportster, I think top speed is 50 knots plenty of room. Plus its fast enough to get back in if weather starts to get bad.
I can get them from one of the supply houses I use. In Mesa. Price is different for what unit size you want (only cool or heat and cool).
Private me and let me know what size.
You have to shuffle Jerry when walking into the water, you can get hit in 3'' of water. Shuffling is basics 101. When I'm in 5' of water I can see them, but I'm looking and shuffling at the same time. I'm more worried about getting hit by a shark.
