Re: Mac 26S: Removing the keel

If you live somewhere near a boatyard, you might at least consider the option of using their travel lift and putting your boat up on jackstands for a little while. Higher upfront cost but saves a lot of time, effort, and headache. Sometimes you can talk your way into a good deal.

Re: Mac 26S: Removing the keel

I pulled my Mac25's keel off a few years ago, but it was considerably easier since the keel sits outside the hull when retracted. We were able to do it on the trailer - dropped the head down off the bolt using a floor jack and dragged it back onto a cradle using a come-along. One option I considered...

Re: Bending the mast

Easy enough to make your backstay adjustable, too - just cut it a few feet shorter, re-swage the eye, and add a 4:1 or 5:1 purchase in the space you just created. BWY also sells a kit.

Re: Peak "the Generator" headsail

I know I'm resurrecting a topic from March here, but I would like to point out that the Mac 25/26's very fractional sailplan doesn't lend itself well to a Code 0 style sail. For a true "drifter" sail I'd almost be tempted to run a masthead halyard (just take it down in a hurry if it starts blowing!)...

Re: M25, Rebuilding the compression post base

I'll dig up some photos when I have a chance. Basically there's a plywood spacer between the top of the keel trunk and the cabin liner that the post sits on. The plywood is suspect, as the liner is sagging a little. My plan is to remove the liner under the compression post to access the wood, replac...

M25, Rebuilding the compression post base

Has anyone rebuilt the top of the keel trunk where the compression post rests? Mine is really starting to sag, probably due to rotten plywood. My plan is to remove the post and bulkhead and cut the fiberglass top off with a oscillating tool. Then I can remove/replace the old core and either replace ...

Re: Mac 25 Restoration

Thought I'd offer an update, 2 years on from the initial restoration. We just finished our first scored series on the boat racing PHRF in the spinnaker class, and we were within a few dumb mistakes of 2nd place overall! I was a little disappointed after we lost the series-deciding race to our rival,...

Re: Epoxy for Rudder

Good discussion here: http://forum.woodenboat.com/showthread.php?204392-Epoxy-alternative-it-West-System I looked for alternatives for my keel project before deciding that West was worth the extra bucks. You're only saving $20-30 with other 5:1 systems per gallon (your rudder project will probably u...

Re: Mac25 Upwind

What's even weirder about scows, not sure if you already read this, is that the boards and the rudders are at a substantial angle relative to the centerline. Since the boards/rudders function best when straight up and down in the water, that means you must always sail a scow with a ton of heel, even...

Re: centerboard winch

Define "floating." Do you mean a brake (2 way) winch? If so, Blue Water Yachts sells this replacement, which they say works for all Mac/Venture models: http://shop.bwyachts.com/product-p/5305-1k0.htm. I bought one for our Mac25 and have been happy with it. Only issue was that I did need to drill a n...

Re: Mac25 Upwind

Mike got it right. To answer your "lift in one direction" question, here's my best shot - bear in mind I'm not a physics (or any kind of science) major although I am a pilot: The typical explanation of lift hinges on Bernoulli and the "sky sucks theory," but that's an overly simplified way of lookin...

Re: Mac25 Upwind

Will do. Been meaning to upload the build log for awhile now. As far as waves go, a flat-bottomed boat will never handle waves as comfortably as a deep, round hull. As long as you're not trying to cross the big lake in an October gale there's nothing unsafe about the Mac, but the hull shape is just ...

Re: Mac25 Upwind

In my experience the around-the-boom furling for the main leaves something to be desired, but it's better than nothing. Hard to do it without the boom starting to droop. There's a reason that MacGregor dropped it on later models in favor of a "traditional" reefing system. The point of the vang is to...

Re: Mac25 Upwind

Hi Fritz, I have a Mac25 on Winnebago - we keep it in Neenah and race there Tuesday nights. Upwind is not the boat's strong suit but we manage to make it work. The important thing is to keep the boat under control and FLAT. It's a light, flat-bottomed boat, which is great for trailering and downwind...

Re: Mac 25 keel cable replacement size

1/4" is pretty big, and probably not necessary. The breaking strength of 3/16 cable is in excess of 3500 lbs and your keel is 625-ish. If you want to replace the cable, Blue Water Yachts sells it pre-swaged and in the correct length.
