From Roland: "Ullmans. Very quick in. Flat water if twinning and perfectly flat. Would suggest asking them to revisit and add shoulders. "
But I had terrible customer service experience with an Oppy sail from Ullman for Rosie, so would not go near them out of choice!
So I got hold of Mike Lennon, who told me that lead time was 'down to about 4 weeks at the moment', but that he would check. Price has also gone up a bit (10%) from what is on their website.
He came back the next day and said that they had a quiet patch and could offer delivery in 2 weeks - i.e. Friday 18th!
So that's what is due to happen...
