The Escape Rumba and the Escape 12 have the same hull
- there are slight differences in the rigging
and the sail, but they are essentially the same boats. The Escape boats were last produced in 2007 and distributed by Johnson Outdoors. The website listed above by svHyLyte has some remaining parts
in inventory, perhaps they have a boom. If so, make sure that you tell them that you are looking for an aluminum
boom - the earlier Rumbas were made with a composite boom.
Another alternative (other than having one made) is to get a boom from another boat that uses the same SmartRig layout. Catalina
Yachts makes two boats with SmartRigs, the Expo 12.5 and the Expo 14 (Yachts and boats for sale - Catalina Yachts
). Probably the Expo 12.5 boom would fit the Escape 12 nicely. Lastly, Laser had a boat in the mid-90s that used the same SmartRig as well, it was called the Escape Expedition, and they also had 12.5 and 14 versions (http://www.shortypen.com/brdboat/escexp2.jpg
