That is a heck of a drive from Edinburgh to Bristol. I love that there is a town called Portishead on the Bristol Channel. I assume the Bristol Channel is where you will be sailing?
There is a Ruffian 23 facebook page and several fleets of active racers as well Irish Ruffian Association
The story of the boat is a fun read if you can find it.
Good luck with re-skinning the bottom. I smell some epoxy work in your future.
