rjack, care to shrink those pictures a bit?
Finally something with aluminum came up! A RIB with alu hull seems to me as one of the greatest ways to make a dive boat. Unfortunately the few available around here are slim speed boats, and not of the roomy type like the awsome Zodiac SRNM series.
We are getting a 100% dive boat for nest season here, so this thread is interesting to us. Nemrod is pounding the all American Bayliner, and he's doing a great job. If he hadn't, I would have... As anything but a beer platform, they stink. Sorry guys!
Anyways, my experiences are with aluminum boats. And they are really great for diving. RIBs are of course just as good, but tend to be a bit wet. So wearing a suit is always nice... But since I end up beeing the sorry guy left in the boat after everyone's dropped in, I like a dry boat anyways. And a rather high shouldered aluboat does a great job for me there. We dive in the North Atlantic, and strong winds tend to be the regular weather. The Great Lakes however, is freshwater. And since I grew up on a large(?) lake, I too know how fast fresh water is stirred up from a little wind.
Our choice for next year seems to be between a Zodiac SRMN and a pure aluboat. I thought perhaps you could be so lucky as to find boats like these in the second hand market over there for around 15K+, but I don't know. We get to deduct the sales tax (25%) if we get a new boat, so new it is.
CE-approved for 200 hp outboard.
