I wrote earlier about separating with a saw. this is wrong. I believe the deck is capped over a lip on the hull. after the rubrail is off you would have to seperate the two using a chisel etc. lots of work ad you probably do damage. most macs that need this much work end up scrapped.

This is a little off subject but have you looked at the book "fix it and sail." Its about a guy that bought a Mac on the cheap and completely restored it. It's meant for anyone who is rehab'n and old trailer sailer but goes into a lot Mac specific details.

i've read where 2 people have pulled theirs apart.
I'm also restoring a mac 21, luckly everything looks sound where i'm not going to go as far as pulling the two halves apart.

if your boat has an aluminum /rubber rubrail you can (carefully), pull out the rubber and unscrew the aluminum pieces. then you can probably cut the deck off with a sabresaw. obviously this is getting into a major rebuild and should only be done indoors. I am parting out a mac/venture 22. I have all the hard parts for sale best offer, mast, boom, keel, pop top, stanchions etc. also trailer. cleveland ohio call 4407770375 10am to 10 pm est. good luck
