Re: Cat 25
The blown out sails overpowering the boat mostly comes when going to weather, and it's a rare displacement boat that is going to go much above hull speed to weather anyway. I think TakeFive's comments were spot on.
Good sails also make a massive difference in pointing ability. I was really disappointing with how my Catalina 25 went to weather until I got a new main and a good condition jib.
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
