Re: Mac 25 Trailer drawings or specs?

That’s the original trailer. They do look short, but that’s the design. The keel should be lowered into its cradle, which reduces the weight on the back of the bunks. I do wish it was a little longer because at some point I’d like to convert it to tandem axles, and I’m not sure there is enough frame...

Re: trailer tire not holding pressure

Sorry for not directly answering the questions, but I think worth mentioning: if the rim doesn’t show any corrosion, check the valve stem. My father had all 4 tires go flat in one season on a cargo trailer after maybe 5-6 years of ownership. The tires were fine, but the rubber valve stems had all st...

Re: Venture 17 - need hatch rails

Yes I believe the originals are teak. I used this to replace the rotted top rails on my 25. I filed the edges round before installing for when I inevitably stub a toe on it.

Re: Mac 25 Trailer drawings or specs?

Here are quick measurements of mine: The trailer is about 21’ L x 6’ W. The V block is about 21” back from the ball hitch and 16” up from the frame. The axle is about 88” (not sure how these are measured, that’s roughly tire center to center). The bunks are about 32” apart and rise from 4” up to abo...

Re: Heat on SS steel

300 series stainless steels (304 and 316 being common on boats) are not heat treatable. They do work harden (cold working), so actually get slightly stronger as they deform (up to a point). If anything, heating could anneal it and make it softer. There are other grades like 400 series and 17-4 that ...

Re: Calculating tow weight - back of the napkin math

I don’t trust Roger’s advertised boat weights at all. The 25 is listed as 2,100 lbs (iron swing keel, so no wet and dry displacement). Anything else in this size range with a keel weighs at least 700 lbs more. So here are some pictures of my attempt at figuring this out on my end. A shop crane, scal...

Re: Venture 17 - Hull ID location

Sorry can’t help with that one, I have a Mac 25, not a V17. I just chimed in because I know Ventures are the older boats and I know that the HIN requirement only goes back so far.

Edit: the picture didn’t load before. Looks pretty good for a free boat

Re: Venture 17 - Hull ID location

68 to 74 it looks like.

My money would also be on pre-HIN.

Re: Venture 17 - Hull ID location

What year? HINs were not required until 1972.

Not sure about registration if it’s a pre-HIN boat. It likely varies by state, so you’ll want to check with the DMV or whoever issues them.

Re: Mac 25 Trailer drawings or specs?

They were welded up out of 3”x1.5” C channel with a 3”x3” square tube tongue. I don’t know the measurements off hand, but could take some basic ones of mine. But my guess is the cheapest and easiest route will be to buy a standard boat trailer and fabricate some bolt-on bunk supports and a keel supp...

Re: Solution for winch fouling? Looks good so far!

Great solution - clean, simple, and effective.

How did you handle the mounting hardware that is now slightly off perpendicular to the deck? Is there a matching wedge on the underside for the nuts/washers to bear on?

Re: Waxing a Trailer

I’ve started spraying fluid film under my vehicles. It’s only been a couple years, but many people in the DIY auto repair world swear by it for northern states where the roads get salted in the winter. It’s the same idea, something that will stay between the metal and the water/salt/oxygen that does...

Re: My Title shows 26ft yet the brochure says 25ft 10inchs

Interesting. The title for my 1983 Mac swing keel shows 25', but I can find no 25' swing keels, just 26' swing keels. I don't have a brochure, bought it used in Key Largo in 2004. Working on restore to sail it around Englewood Florida - Pete The Mac 25 was a cast iron swing keel and was in producti...

Re: Bahamas 2025 Planning

I’d skip the generator and AC. The inter-webs claims the DF90A can produce 27 amps at 12V. Depending on the batteries, a generator may only do better for about an hour of bulk charging, then the batteries will stop accepting current much higher than that. For A/C, the time I spend in the Bahamas in ...

Re: Vang or preventer?

A preventer can, and generally should, be rigged to the end of the boom anyway, so that one isn’t inherently a problem. If your boom has the same thin stainless tang that mine does for the mainsheet block attachment, you will want to add another attachment point. The 1st time the preventer is loaded...
