1978 Sailboat MSY 38 Boat in Denison, TX 75020 US

Just listed! Pictures are about 5 years old. New pictures coming soon.

"Excitable" is a Dennis Choate designed Racer/Cruiser. She looks great for a boat of her age. Recently repowered with a Beta Marine Engine, she also has air-conditioning and refrigeration. There is little information out there about this particular design but the designer himself is well known and still active in the marine industry. There is a marine survey from 06/21 available by request. $41,000.00 Survey valuation at that time.

The IOR (International Offshore Rule) was a rating system used in yacht racing from the 1970s through the early 2000s to create a fair and balanced competition between different types of sailing boats. Developed by the Royal Ocean Racing Club (RORC), the IOR was designed to measure a boat's performance potential by assigning a numerical rating based on its dimensions, sail area, and other factors like hull shape, displacement, and length.

The idea behind the IOR was to create a system that allowed a diverse range of boats with different designs to compete against each other on a relatively level playing field. The rating formula took into account variables such as:

• Length Overall (LOA): The total length of the boat from bow to stern.
• Beam: The width of the boat at its widest point.
• Sail Area: The total amount of sail area the boat could carry.
• Displacement: The weight of the boat, which influences how it interacts with the water.
• Hull shape: The design of the boat, including how narrow or wide the hull is.

While the IOR system worked in its time, it also had some limitations, especially as the rule tended to favor certain designs that worked well within the system but were not necessarily the fastest or most efficient in all conditions. Over the years, this led to boats with "IOR-style" features-often with heavy, wide hulls and relatively small rudders-that were not always ideal for general cruising or performance in all conditions.

In the 1990s, the IOR was replaced by other systems like the IRC (International Rating Certificate) and ORC (Offshore Racing Congress), which are still in use today, aiming to address some of the limitations of the IOR and provide more balanced racing in modern times.

In short, the IOR was a key part of yacht racing history, shaping the design of boats during its time and fostering competition across a wide variety of boat types.
