If I had a dime for every Blister!
I have a 99 Mac and found about 12-15 blisters----i stopped counting after ten. Most of them where about the size of dimes, but one in the centerboard trunk was 3"x1"xquater inch deep----i had to fill it wiht resin. Sure i should have called Roger Mac. himself and bitch him out, but i dealt with him about the leaky deck hardware. Mac's response--"well , about half of our boat leak when is rains--it's because of the bounding during high speed." thats b.s., because i just bought the boat! Very Apathetic and unconcerned response from Mac. corp. I spoke to a few Mac owners and it seems that the blistering problem seemed to increase in the 1999,2000 boats---not sure about current. From my experience, i don't think they will address the problem until sales drop and Q.A. is improved. Good luck friend I have to say, i like the boat, even though it's not perfect. One good thing came from the leaky cabin-----the boats name: THE SOGGY SCOT (thinking of sending a picture of a drunken Scot.in a kilt to Roger Macgregor, drenched with water and standing in front of my boat with her name in big letters--The Soggy Scot)------hehehehehe...
