One very dirty 420
And after a day of cleaning
she needs a bit more work, like varnishing and maybe a couple of coats of paint on the hull, and needs some fittings, like trapez fittings, a new slot gasket, new battans for the main and modifications to add a highfield lever for the Jib halyard, but she is looking a lot cleaner.
We have worked it out that she must be well over 40 years old with a sail no in the 6000's. but she is very light, much less than an enterprise.
We have decided to call her Billy Boy.
