I am not 100% sure, but are those yards not closed, as I recall Appledore closed some years ago, and a quick search of the boat her self shows that the Plymouth yard was taken over, and does not seem to be in the yacht business. Also she is nearly 10 years old with a build time of over 5 years back then. Will Tubs wait that long, and I think the £200m budget for the new GB Yacht would not stretch to Vava 2 costs.
PS tender is not British
