They should have a class for 30+ year old boats at the 40th aniversary regatta.
Who's gonna run the first Vintage Hobie 16 Regatta/Rally?
Which goes back to the original question. What is the cut-off year? What defines vintage?
Not sure it is just the date of the boat, but would you not have to have age appropriate
Sails, Blocks, Tramp, harness, rudders and most importantly of all crew? What about the Mast? For a car to be truly vintage, do not all of the parts also have to be vintage?
Could you set the time line to be something like prior to the upgrade of Parts X say for example Main blocks
