Back to the topic of jet power, this is something I was VERY interested for years. Wouldn't it be great not to have to worry about snagging a crab pot? However, from everything I've read, jet drives don't do well on deep vee hulls. Best results require a minimum of 3' flat bottom before the intake. Yamaha seems to have figured out the best combination of deep vee entry and flattened pad on their 2300 jet boat.

I really need the deep vee to cary to the stern to run in the choppy sounds, so I chose prop and crabpot dodging.

The Jetpak concept doesn't appear to work as well in real life as it does in paper. Look at their videos of anything but a RIB, and the boat operates like it's bogged down in quicksand. I think it falls into the same problem as jet outboards, where the intake must take a very sharp turn up into the drive unit and back out, wheras a purpose built jet boat has a more linear intake/output lineup.
