I discovered a few neat tricks while storing hanging clothing on my previous boat, a Catalina 27. Obviously, space is always quite limited, which is something I can never seem to get through to my loving wife. If she were making a long voyage, the entire boat would become a hanging closet/locker. Guys don't usually need much more than a two-foot-wide hanging locker and a drawer or two--that's it!
Boats, unfortunately, have their own, unique odors--usually somewhat musty. Much of this is due to a lack of air circulation. I overcame this problem by installing a couple vents in the hanging locker, one near the bottom, and another near the top. The one at the top will chimney the air through the locker, but the volume of air was not sufficient to keep things as odorless as I would have liked. Therefore, I added a small, 12-volt, computer fan to the top vent. The fan draws very little electricity, the volume of air it moves is incredible and when the boat is open you can switch it off.
Vacuum bags specifically designed for hanging clothing are wonderful to reduce the amount of space required for clothing, but they do have their drawbacks--the clothes are always wrinkled. When I'm working, which is sometimes 7 days a week, I wear black trousers, a satin shirt, matching tie and a silk vest. I'm an entertainer. I sing and play an arranger keyboard and in this business every day is dress-up day. (Gotta' look good for the ladies!) Therefore, my biggest challenge for the upcoming winter will be to find a steam-iron that runs on 12 volts so I can press my shirts and slacks. There must be one out there somewhere.
