Accomodation

The J/30 is a popular sailing boat that was designed by Rod Johnstone and first introduced in 1979. It was built by J/Boats, a well-known American sailboat manufacturer. The J/30 was specifically designed as a one-design racer-cruiser, meaning it is built for both competitive racing and comfortable cruising.

Here are some key features and characteristics of the J/30:

1. Size and Dimensions: The J/30 has an overall length of 30 feet (9.14 meters) and a beam (width) of 11 feet (3.35 meters). It has a moderate draft, typically around 5.5 feet (1.68 meters), which allows it to perform well in a variety of conditions.

2. Hull Design: The boat features a sleek and efficient hull design, with a relatively narrow beam and a deep fin keel. This design allows for good upwind performance and stability, making it a competitive racer.

3. Rigging and Sails: The J/30 is equipped with a masthead sloop rig, which means it has a single mast and a forestay that extends to the top of the mast. It typically carries a mainsail, a genoa, and a spinnaker for downwind sailing. The sail area is optimized for performance, allowing the boat to reach high speeds.

4. Interior Layout: The J/30 has a comfortable and functional interior layout, suitable for cruising and overnight stays. It typically features a V-berth in the forward cabin, a main salon with settees and a folding table, a small galley with a sink and stove, and a head (bathroom) compartment.

5. Performance: The J/30 is known for its excellent performance on the racecourse. It is a responsive and nimble boat, capable of reaching high speeds and maneuvering quickly. Its design allows for good upwind performance, making it competitive in a variety of wind conditions.

6. Class Association: The J/30 has a strong class association, which means there is an active community of owners and organized racing events specifically for J/30 boats. This provides opportunities for competitive racing and camaraderie among owners.

Overall, the J/30 is a versatile and well-regarded sailing boat that offers a balance between racing performance and cruising comfort. Its design, size, and class association make it a popular choice for sailors who enjoy both competitive racing and leisurely cruising.
