I bought this boat from Bernie a few months ago and have paddled it quite a bit since then. Every time I get to the takeout I just say " man, I love this boat!" Bruce can attest to that. In fact, I think he's getting quite tired of hearing it because he told me to quit telling him and post this review.
I'm no boat critic, but i'll give it a shot.
Last weekend I got to run Giant Gap on the North Fork American. This is a classic California whitewater run. 14 miles, with LOTS of meaty class 4 and 5 drops in a deep, remote canyon. This run put me to the test, it also gave me more reason to "spread the word" about the H3.
This boat is about river running and creeking .
If you are tired of getting SPANKED on the more difficult stuff because your boat is designed to be on end, or is just plain tippy, consider this boat. If you want a playboat, get a playboat too!
The H3 255 may just be THE BEST KAYAK CONVERSION EVER. PERIOD. (although, I've only paddled 2 other conversions)
The H3 is a very predictable and stable boat. Primary and secondary stability, even when it's under water, is excellent. When you're in the thick of it you can actually focus on, and make, your moves because you're not fighting to just stay upright.
And when you do momentarily run out of talent and pick some stupid line that sends you through some nasty slot / pourover with water crashing on you from every angle
, it re-surfaces very quickly and smoothly so you can get the heck out of there 
I think it's an 80 gallon boat but it doesn't feel like a pig to me.
It seems to have plenty of speed, it accelerates nicely above those big boofs.
It is very easy to control your ferry angles, this is a nice feature that I have been missing in my X.
Did I mention boofs?
Big Water, Squirrely Water, no problem. It seems the harder the water the better it performs.
What else......Fit. I am 6' 175lbs. Trim a little superfluous plastic from the cockpit rim and there's plenty room for your thighs. My waist is about 32" I use some hip pads that are about 2" on each side. The cockpit is huge, length wise. I don't think my feet even go under the rear deck. I'll check that later. The bottom is wide and flat so you can get your knees down low & wide while you're doing flat spins.
Tons of room for overnight gear! Don't put a bulkhead in it.
I can't think of any bad things to say about it. Oh, it is a little hard to roll, but not HARD to roll. And i probably won't be swapping ends in it. But thats what the Flipstick is for.
Hope this helps somebody.
Have fun!
. We did switch at the takeout one day but there was no real moving water, so all I can say is it felt a little tippy to me. This was before he started cutting the saddle down wich he says helped a lot.
