Accomodation

The Shannon One-Design (SOD) is a class of sailing boat that was designed by Walter J. McInnis in 1929. It is a small, one-design racing sailboat that was originally built for use on the Chesapeake Bay in the United States.

The SOD is a 20-foot keelboat with a sloop rig, meaning it has a single mast and a mainsail and jib for sails. It has a traditional design with a narrow beam and a full keel, which provides stability and allows for easy handling in various weather conditions.

The boat is constructed of wood, with a planked hull and a wooden deck. It has a small cabin with basic accommodations, making it suitable for day sailing or overnight trips for a small crew.

The Shannon One-Design class is known for its competitive racing scene, with regular regattas and championships held for SOD sailors. The class association promotes fair and equal racing by enforcing strict one-design rules, ensuring that all boats are identical in design and equipment.

The SOD has gained popularity over the years due to its affordability, simplicity, and the camaraderie among its sailors. It is often considered a great boat for beginners to learn sailing and racing skills, while also providing a challenging platform for experienced sailors.

Overall, the Shannon One-Design is a classic and enduring sailboat that continues to be enjoyed by sailors on the Chesapeake Bay and beyond. Its timeless design and competitive racing scene have made it a beloved class in the sailing community.
