We just bought a S238 and we have put about 10 hours on it trying to tune in the best Surf wave. I have not found the perfect wave yet. I have tried running full capacity of everything in the boat( hard tanks, two bags in the back and the bow bag) with the quick surf tab and the wave looked good but didnt have the push. felt very soft while riding. Then i took all the weight out of the bow to see if i could get a higher firmer wave and that didnt seem to help much either. We are new to Surfing but plan to be doing A LOT of it this summer and i need to figure this out. Anyone found the secret recipe for weight/location of the weight speed ect. on this awesome boat? Thanks for the help a head of time.
