It all seems to have worked fine. We made it back after a lumpy crossing at a steady 25knots.
Must dash, but before I go, thanks, Brian for all your sterling homebase support, for ringing round and organising phase 2 - the real repair.
Huge thanks to Mark, for long suffering help. Just sorry we messed up the Spanish run and your holiday through my rubbish driving.
Thanks, too, for all the offers of help, support and good wishes from the members of the good ol' RIBnet Forum. All much appreciated.
Can't wait to get back on the water with beefed-up go-anywhere tubes!
