Accomodation

The Southern 21 is a popular sailing boat that was designed by John Bennett and built by Southern Boatbuilding Ltd in the United Kingdom. It is a small, trailerable yacht that is known for its sturdy construction and excellent sailing performance.

The Southern 21 has a length overall (LOA) of 21 feet and a beam of 7 feet, making it compact and easy to handle. It has a moderate displacement of around 1,800 kilograms, which provides stability and a comfortable ride even in rough conditions.

One of the standout features of the Southern 21 is its lifting keel, which allows the boat to be easily launched and retrieved from a trailer. This makes it ideal for sailors who want the flexibility to explore different sailing areas without the need for a permanent mooring.

The boat has a spacious cockpit with comfortable seating for the crew, and the cabin below deck can accommodate up to four people. The interior layout typically includes a V-berth forward, a small galley area, a saloon with seating and a table that can be converted into a double berth, and a separate head compartment.

In terms of performance, the Southern 21 is known for its good upwind sailing ability and overall stability. It has a fractional sloop rig with a mainsail and a roller furling genoa, which allows for easy sail handling and adjustment. The boat is also equipped with a reliable outboard engine for auxiliary power.

Overall, the Southern 21 is a versatile and well-built sailing boat that is suitable for both cruising and racing. Its compact size, lifting keel, and comfortable interior make it a popular choice among sailors who value convenience and performance.
