I have a 1987 Mac 25 and the front deck, cabin top and transom are plywood cored.
I am not sure if there is any in the hull.
Water leaks in to plywood at screw holes for hardware.
Hope this helps.

To dcaldarona: If your new boat is worth $20,000.00 or more, go to W. M. or BWY. I replaced all my running rigging thru a line dealer on ebay, that sells Nova Tech XLE line. Google there site for information on there line, if it meets your spec's go to ebay and search Nova tech XLE the seller I used...

I'm not telling you what to do, I'm giving you the recommended line sizes for the MacGregor 25.
Main Halyard 5/16"
Jib Halyard 5/16"
Mainsheet 3/8"
Jibsheets 3/8"
Outhaul 1/4"
Topping lift 1/4"

I hope this helps someone.

Thank You Sumner for your reply:
I will follow your advice and order the 316 stainless wire because
there will be a next owner and the boat can wind up anywhere.
Thank You

First thing, take care of my compression post problem. Thank you Sumner and the others for your replys. Mods; 1 Rudder Craft rudder 2 aj...

The Cuscus Thank you for your reply. I have one more question for you. I was looking at your photo album on the other site and you did the keel mod. Was it worth the time and trouble? I'm not a racer, but would like to squeeze every bit of speed out of this boat. I don't want to build a platform lik...

This is my first sailboat and the only one I have ever been on. I got into sailing when most people my age are looking at cemetery plots. I bought the boat to give me something to do, to stay out of the bars. Now I think it would have been cheaper to go to the bar. The only thing the PO did,was wear...

Went to Google Images and typed in MacGregor 21
There are plenty of pictures with backstays and shrouds.
Good Luck

Freedom 77 Thank You for the post. The stainless steel L-bracket that supports the mast post on my boat is bent down from the pressure of the mast. Blue water yachts does not sale this part, so I will have to have it made at a shop I use. I was thinking of making the bracket longer so it is up again...

Sumner, thank you for your reply. Have been looking at your post's for years on a different site, and have been impressed by your mods to your trailed and boat.
