It’s interesting the way that equipment moves onwards and upwards. Both of the boats on the FF stand at the Dinghy Show had switchable rachets for the genoa sheets.
This is the arrangement on Justin Waples’ boat from the workshops of Phil Evans. If you have a Mk 10 from Phil Evans at your Club and compare it with the above, you will find that Phil has found the space to move the attachment loop backwards (to the left in this photo) and that gives space for the becket of the ratchet block.
On the Ovington finished boat, they had managed to get a small ratchet cheek block (from the same Manufacturer’s series I think) screwed down on to the platform. Both implementations used switched ratchets. To see the Ovington implementation, you’ll need to wait for the BIFFA video tour of the boat.
There will be many husband/wife teams who will be keen to have a think about this!
