J Class Yachts

In the 1930s, the J Class yachts raced under the Universal rule, this rule used waterline length, displacement and sail area to control the racing condition and rating of these Formula One racing yachts of their day.

Now in the present day, there is mixture of refitted surviving yachts along with a number of new yachts built to original hull lines with more yachts in build now and planning to be built in the future.

These yachts can no longer be raced in their original designed conditions due to their luxury interiors and the need to adhere to modern marine standards and as a result their speed potentials are different. Their performances are also determined by their overall design and it was decided to use a modern velocity performance prediction technique to better estimate each yacht’s performance across a range of wind speeds and course types to produce fair racing and rating.
