kennya Thanks one and all for all the good input. I have a few months to work out my allotment cooling method. I have a Lot to think about..

Cruisingdad Yotphix,

Assuming that you meant DOCK and not **** in you previous post, I will say that the Red Neck Engineer leaves his on the dock all the time and does not move it. Although, I am not sure his boat moves either.

If you meant the other... well, I am not even going there!!

sailingdog OMG... I can just see this... bunches of air conditioners sitting on the dock with long silver insulated ducts dropping in to the water..Some wiseass comes along and fills the ducts with salt water, and then people coming back to the docks and blowing salt water all over the insides of their boats. LOL

yotphix If people are ducting the air into their boats and removing the units to dockboxes before going sailing, why not just leave the units on the **** altogether and duct into the boat with insulated duct while alongside? Beats carrinying the things back and forth.

What the cuban wants, the cuban gets...

cardiacpaul Dad,
I saw a "silver snake" ductwork job on a stinkpot @ grandpappys, and while it works like a charm, the Cuban nixxed the idea, something about, "Oh, hell no, thats too far out there"

I'm on texoma as well and on a 27 catalina, a 5k window unit in the companion way is sufficent, albeit quite redneck and rather unseemly to crawl over. The carry-on in the front hatch just doesn't cut it by itself @ the dock in August. Not to mention my back gets a workout carting them from the dockbox to the boat & back

On the 33, I need both and it takes a couple of hours to become cool(er)

ebs001 Kennya, you keep dropping one of the zeros in your post. The Coleman Seamach is a 13,500 BTU unit and the window shaker you have now is a 5,000 BTU unit. According to the website you provided the SeaMach is made for the harsh marine environment and would certainly be large enough to cool your boat. Everyone uses a generator to cool their boat when away from the dock, so power is not an issue. The only problem in the above post that I think you will have is changing the centre of gravity and therefore your righting moment by mounting a 100LB unit on deck. It also will have to be well secured to accept the pounding it will take.

kennya You are partly correct I am In Oklahoma, But on The Grand Lake of the Cherokees. My boat is a Spirit 28, with a full insolated headliner. I have taken a small 500 BTU window unit and just set in the companion way and cooled the boat. Not easy to get in or out of the cabin.

Cruisingdad Kennya & all,

I am assuming you live in Oklahoma and may even keep your boat on Texoma?

Well, I would be very surprised if 1300 BTU is going to cool your boat. Maybe you just have a very small boat? I don' know. I have a 16000 & a 12000. The 16 really is almost enough... excpet on the hottest & coldest days (it is harder to heat then cool on a reverse cycle).

As far as the top mount unit, You might save a few bucks and try what I saw another guy try. Ok, now, this is reall-real-real red neck engineering, but:

THer is a guy on another dock that took a large home mount unit, built a wooden box around it for weather, left open the exhaust (hot side) side and ran house style ducting into the hatch from the cooling vents. The unit sits on the dock.

I am not neccessaril reccommending this, per se. I have actually thought about sending it into Americas Funniest Home Videos, but am afraid of death threats from the LCRN (Local Chapter of Red Necks). Still, it is a cheap and easy way to do it.

If you do want to go with a small water cooled unit, Mermaid makes one in very small BTU's and they are supposed to be easy to install. They look like they would be. Still, as has been pointed out, you will need a genny to run it away from dock. At dock, it is no problem, of course.

PS The water cooled units work very well, even in the tropics... I can tell you. It is not how cold the unit get that I have found is the limiting factor, it is how "hot" the deck is and how much of that is radiating down with full sun.

But this unit would need a 20amp 110VAC power feed, making it impractical for a lot of sailors. Water-cooled AC units also are more efficient for permanent installation on a boat.

Unless the boat is really large, it is very unlikely that it will be able to support the electrical load required by the AC unit in question. Water cooled units are only more efficient in areas where the water is cold enough to cool the unit.
