Just wondering, how much increase in drag will you see if you dont have a perfectly fair bottom on your hulls? Are we talking percentages or less?
For the serious racer I assume every second counts, but for us hobbyists, is it worth it refaring the hulls under the waterline or is the time better spent on the water? I tend towards the latter, but my crew isn't that sure.
For me, it's all about the "head game". If I know my hull bottoms are some of the sleekest in the fleet, I have one less excuse to crowd my brain as to my performance. Likewise with the rest of the boat, if I know it's tip-top, I don't have to think about it.
