About the SeaPerl 21

First built in 1982 by Marine Concepts, the Sea Pearl 21 pairs a forgiving sharpie hull with a simple junk-style rig that keeps solo sailors and maintenance both approachable. Roughly 415 were produced, so parts and community knowledge for this trailerable cruiser are still findable today. Many owners add the optional amas kit that turns the boat into a trimaran, a modification popular among Watertribe and Everglades Challenge competitors.

Hi Etienne, I finally installed the new Tramp Net and thought you might like to see the result. I'm quite pleased with the fit and finish. I'm a happy customer!

About 4 years ago I purchased some trampolines for my catamaran (Chincogan 52ft) and they are amazing and very happy with them. Hence we now want to replace the net that goes from the front to the bow sprit.
