JK-
The supervee is a great boat, but don't plan on using it over in the forks area!!! It's drift boats or nothing over there. The supervee will provide a good ride in the salt, but I prefer the 18' semi-vee (like the intruder series or the woolridge sport series) because it is a little easier to handle when the water flows are low in the sky and snoqualmie. I personally have debated between jet and drift boat for a couple years now and I am leaning towards the drift boat. You can do all the rivers and with the coming salmon restrictions the amount of opportunity in the sound will be very limited. Good luck.
