Thank you, Bill
The Hunter 26 centerboard weighs about 45 pounds; the 240 centerboard should not be any heavier, and is probably lighter.All in all, I think damage from a lowered centerboard is a higher risk than a raised centerboard. A broken line from bad roads is problematic, but forgetting to raise the board before launching is almost a certainty. Some day you will forget to raise it.Besides, if the road is that bad, imagine the strain the rest of the boat must endure. And if the centerboard had been lowered, wouldn't it bounce up and down, causing all sorts of damage and grief?I read a letter (in a powerboat magazine) from a powerboat clown who was bragging about how some people couldn't launch their 'sailbote', and asked him for help. He tied his ski rope to the back of their boat, then opened the throttle. The problem was the centerboard -- it had been lowered, and was binding on the trailer. Powerboat Clown damaged the centerboard, the centerboard case, and the trailer. The idiot thought it was funny!
