AC Cowling for the Boat Air Conditioner

2007.06.14

When we moved back to the shore from the cess pool in 2003, we lived on the boat for the summer before buying this house. During that time, I bought a 10.000 btu air conditioner to cool the boat. I also built a cowling for over the hatch, to match.

When we moved ashore, we brought the AC unit with us, since the new/old house does not have central AC and the summers here are brutal.

Finally, after four years here, I'm once again working and earning enough to have a little spending money, so the first thing I had to do was buy an AC for the boat one day when the temps hit 95. Unfortunately, it is a different AC unit than the one that went before and taller and narrower than the old one, making the old cowling obsolete.

The last cowling was stitch and glue luan, lined with foam insulation. This time, I decided to skip the luan and just glass in some foam. This has had two benefits so far. First, I didn't have to mess with cutting and fitting foam inside the luan and second, I'm getting a much better shape, being able to work directly on the foam before glassing.

It's been a long, hot summer. Much of it, I have been working and extremely fatigued due to the heat. So, progress on the Cowling has been slow.

I did discover that the foam I was using is not suited to Glassing over, and by the time I got to a type of foam that would work, it priced me out of doing it in foam. Especially when I could do it in foam and luan for $20 or so, plus the epoxy and paint.

But, after a visit to the Doc and getting put on High Blood Pressure meds, I have a lot more energy and have made a lot of progress this week.

Wherein we finally come close to finishing this simple project.

The smaller, inner cowl was built because we've been experiencing some freeze up of the AC unit. Something that did not happen with the other unit. I believe it is because this new machine has the outlet tilted up and it mixes more with the return air. So the inner cowling is an attempt to keep that separate. The good news is, it does take longer to freeze up. The bad news is, it is still freezing up. I may end up buying another AC unit, one with a vertical air outlet... which of course will mean a different cowling if the shape is different... sigh.
