I'll second Mike on the Wooldridge. I have the Sport Offshore 20'. It is a great fishing platform. Bracket, 115 and 8 hight thrust Yamahas for power/trolling. I upgraded to 50 gal fuel tank, switched some seating arrangements. Wooldridge was easy to work with. They came out with the 20 Super Sport Offshore with a sharper bow and deeper V (I think it is 40 degrees/18 degrees) which would be nicer for choppy water. Mine is 30/16.

As mentioned there are trade-offs and if you can get some test rides, that will help you. Welded over rivets is a good thing. Sharkhide/paint when the boat is new is a good thing. Wished I'd gone ahead with the Zolatone paint on the inside.

Aluminum is light and noisy. The wind can push you around. I'll take the fuel economy, though. About 500 miles per the chart plotter at Sekiu the past couple of years and I burned about 70 gal of gas. The first year we used the big motor for a lot of trolling - it runs just about right. Last year I used the kicker a lot more and saved a fair amount on gas.

I fish the Straits a lot and make some trips to LaPush. No problems on the big water.
