With a self-bailing cockpit, low profile topsides, large transom, huge sail area with main, jib and symmetrical spinnaker, the Andorinha is capable of exhilarating bursts of speed.

The use of epoxy throughout and the fact that hull and deck external surfaces are protected by a fibreglass layer ensures a low-maintenance, long lasting dinghy.

Demonstrating great performance in all points of sail, the Andorinha is a great choice to practice the sport of sailing, be it racing or leisure sailing.

Building the Andorinha:

Amateur boatbuilding is one of the most pleasurable hobbies for people who enjoy making things with their own hands. Designing boats for amateur construction is also fascinating. However, designers involved with this segment of architecture are required to be aficionados, if good results are to be expected.

The hull panels are cut-out in plywood and stitched together. As the panels are pulled into place the hull takes is final form and is ready to be glued and covered with fibreglass.

A building manual accompanies the plans, showing, step by step, all phases of the construction.
