Last summer the family and I came across a '89 Sun Tracker Party Barge 24DL for practically a steal, so we took the plunge and bought it. Like many pontoons of this age, she was in very rough shape, Rocky Raccoon and family made home in the boat for a long while...

I have a question about the lifting strakes for the more experienced out there. This middle toon has the Harris PII performance strakes, which are negative angle. I was going to weld strakes on the inboard side of the outer tubes. Can these strakes on the outside tube be positive angle? Do strakes have to be all the same angle (positive or negative)? Can you mix the two? I'd like to do all my welding to the toons while it's light and I can flip it over easily to weld down instead of on a trailer and up.
I have pics to post of the progress so far, I have to upload them this weekend.
