The company, which also built the Siren 17, obviously knew what people were looking for in a trailerable boat because the Sirius 21 sold very well, and it continues to maintain its value on today's used market. This boat also has a "pop-top", a feature where part of the cabin roof can be lifted up and enclosed with a canvas to provide standing headroom while at anchor. A variation of this boat with a reverse sheer transom was marketed as the Sirius 22 during the mid 1980s. People interested in trailerable sailboats may also want to check out the MacGregor line of boats, including the Venture 224, MacGregor 25, and water ballasted MacGregor 26. All are variations of the same 25 foot sailboat, and all are designed to be very inexpensive, light weight, and highly trailerable sailboats. Although these boats were manufactured in the United States, thousands were imported into Canada, and they are easy to find on the local used market. by Michael McGoldrick. [ Copyright & Disclaimer ]
