I recall that it was changed a year plus ago from 1099 but at Shoreham the Hartleys race off 1080 (Merlins 982 and Phantoms 1020 )
The reason is that much of our sailing is done in planing conditions and the Hartleys are so much faster than the older , more rockered Wayfarers .
We still can’t save our time against the Merlins but their fleet has Olympic medallists and National champions in it and are fast enough to beat an ex-Hornet champ on the water sometimes !! We have good racing with most of the Phantoms , the RS200s and the modern Lasers tho’ .
