The number one pitfall of re-purposing a sail is that if ANY modification is needed, you are likely to be wasting your money.
Thanks, Shark. Yes, there's that.
I can not count the number of times customers would bring in sails so past their prime that you could poke a finger right through the 40-year-old, sun-rotten Dacron. "Well, we don't race or sail in any rough conditions..."
"I don't want to spend a lot of money..."
"A new sail costs more than what I paid for the boat!"
Yeah, and why do you think that is?...
With that level of preparedness, I can only guess how refined their weather forecasting is. I'm thinking level: Rimas.
