The German company, Klepper, is best known for its canvas-covered kayaks, but Klepper not only makes a sailing rig for their kayaks, but has also built other sailboats. The "Master" is a canvas covered sailboat that can be folded up and transported without a trailer. It takes quite a bit longer to set up, rig and pack up these boats than normal sailboats!

I always liked the 15' fiberglass Klepper "Trainer"

Klepper also built the FAM (18') and Traveler (20') pocket cruisers
