Liveaboard Cruising Mods Mac/Venture 25

Post by Sciencelooker » Tue Sep 26, 2017 11:04 pm

I bought my Mac 25 in February. After spending a few hours each day for five months, its ready to be an off-grid tiny house that can cruise the Florida Keys and Bahamas. Here is a link to a video showing some of the mods and a cruise around Biscayne Bay.

Thanks for the kind words. The boat survived the hurricane in the keys because it was tied to its trailer. This winter, I plan to put the mast on with some mods to allow the mast raising system from the Mac26. I also need to mod the V-Berth to make a small locker for chain/rhode where the windlass is on the front deck.

The mod that cut off the bunk under the cockpit so the hot side of the air conditioner does not circulate back into the cabin, worked, but in the long run was a mistake. I will make a more difficult partition that puts all of that space inside the air conditioned part of the cabin. This lets the space be used as a spare bunk and also keeps stuff stored there from being cooked by the hot exhaust from the A/C. (I leave the hatch to the under-cockpit storage open when running the air conditioner so the hot air has a way to escape) For all its complications, I like this location for the air conditioner because it doesn't involve a huge unmovable box up on deck. It worked wonderfully on the test cruise.

The Honda 2000is generator fits through the existing hatch to the under cockpit locker like it was designed to go there. It is light enough to easily lift in and out. I really like the fact that I can get it out of the cockpit and lock it up when not in use.

Will definitely post again when more videos of the future mods are available.

Other stuff I do, mostly cinematic gear, is on my other Youtube channel called sciencelookers

Hi Scienclooker,
I have a 26S and have been considering putting a 5k AC unit in a hole in the bulkhead between the aft berth and the laz. There is enough room in the laz for the unit (barely) and I figured it would work as long as the laz hatch was kept open. Having done something similar, do you have any insight for me? I have tried in vain to find anyone who has done anything remotely similar to what I am considering. I really don't want to cut that hole in the bulkhead and then find out there is a big problem I did not foresee. Thanks for any input you might have.

Absolutely inspiring! Thanks SO MUCH for taking the time to make the excellent video and share in your adventures of what's possible if a person will just go out and do it. I should be more like you. I really enjoy making mods to my 26X. I spend more time doing that than boating. (Water is scarce here in New Mexico.) Please, sometime, share more of your adventures. Again... Thank you.

To people considering this option, know that these boats are built to be light. There are better options if you want to
have a lot of comforts like a big fridge and AC and the fuel and generator to run it all for a week. These boats won’t sail well with a lot of weight on them, and there are better powerboats out there if you don’t care about sailing. For off grid living my advice is to keep everything small, limit your need for gasoline. Use solar. Have a small marine freezer that will operate it. Use fans instead of AC or cruise in the winter months. If you really want to cruise farther then a few days from The city and do it under sail, you must be careful not to compromise the boats sailing ability.
