I suspect that you have an Alerion Express 20. I believe it was designed by Carl Schumacher, who designed many notables such as the Express30 and 35, both fast boats. I believe the alerion
line was designed to look classic above the water
line, but with a modern under body. the boat seems to be fairly quick for its size, except for off the wind, because of its non overlaping head sail. I do''nt know if the boat is rigged or can be rigged for a
spinnaker. A friend of mine has one and I''m sure he would be happy to share Info. ( peasefam@dca.net )
