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)
