Update...and many thanks to everyone for your very helpful comments! I made contact with the seller via his sailing blog
and we are in much better shape.
between me and seller are (touch wood) good and we have got a lot of stuff done, removing the misunderstanding caused by the rather jejeune broker
So the seller took many of our initial observations on the chin and is making them good; also it turns out he is not "doing the rigging himself"; rather he is having it manufactured by what seems to be a very swept-up firm that does much bigger boats; he is only doing the fitting.
Oh, and he had no idea the broker
was trying to force a dumb one-sided contract
down my throat, and that this alone nearly cost him the whole sale
. We rewrote the contract
in 20 minutes, exchanged a couple of emails to confirm, and he then instructed the broker what to write.
Now we have just done the survey. There's a bunch of stuff, one or two items potentially significant and may need further investigation. I'll be going direct to the seller for sure. Hopefully we'll agree a way forward otherwise (thank goodness) either of us has the option to void the contract. As originally drawn, I'd have been forced to complete.
Watch this space! And thanks again.
