Accomodation

The ALOA 21 is a sailing boat designed for cruising and racing purposes. It is a small, trailerable sailboat that offers a combination of performance and comfort. Here are some key features and specifications of the ALOA 21:

1. Design: The ALOA 21 is designed by the French naval architect Jean-Marie Finot. It features a sleek and modern design with a focus on speed and stability.

2. Construction: The boat is typically constructed using fiberglass, which provides durability and strength while keeping the weight relatively low. This allows for better performance on the water.

3. Size: The ALOA 21 has an overall length of approximately 21 feet (6.4 meters) and a beam (width) of around 8 feet (2.4 meters). Its compact size makes it easy to transport and launch from a trailer.

4. Sailing Performance: The boat is designed to offer excellent sailing performance, both in terms of speed and maneuverability. It features a deep keel and a well-balanced hull shape, allowing for efficient upwind sailing and stability in various weather conditions.

5. Cabin Space: Despite its compact size, the ALOA 21 offers a comfortable cabin space for overnight stays or short cruises. It typically includes a V-berth, a small galley area, and a portable toilet.

6. Rigging: The boat is equipped with a fractional rig, which means that the forestay (the wire supporting the mast) does not reach the top of the mast. This rigging configuration allows for better control and adjustment of the sail shape.

7. Trailerable: One of the notable features of the ALOA 21 is its trailerability. It can be easily transported on a trailer, allowing owners to explore different sailing locations without the need for a permanent mooring.

8. Racing Class: The ALOA 21 is often used for racing in various sailing events and regattas. It is designed to meet the requirements of the International Rating Certificate (IRC) and can compete in different racing classes.

Overall, the ALOA 21 is a versatile and well-designed sailing boat that offers a balance between performance and comfort. It is suitable for both experienced sailors looking for a competitive racing experience and those seeking a comfortable cruising boat for short trips.
