So I ended up thoughtfully disposing of my Triton 721 Shebumi due to it being an osmosis riddled p.o.s...
I am now the proud owner of Barnacle Bill III, a 1986 Northshore 33. I'd love to hear from any other NS33 owners out there! I have been sailing her (him?) In Twilight races as well as cruising Brisbane Water and a couple of trips to Sydney Harbour. My next trip will be a long weekend exploring everything between Barrenjoey Head and the Hawkesbury River Railway bridge!
