cheap sharpie

Damn that's a good buy! I first started sailing in 1960 as bailer boy sheet hand on lightweight sharpies. Not really for the fainthearted. I was down in Victoria a fortnight ago to pick up a Corsair for my grandkids to learn in. Selling my Solo on eBay at the moment, finishes this afternoon. I bought that from Albert Park where the original poster on this thread sailed.
Need a crew of 3 to sail a Sharpie really and the forward hand needs to be beefy!
I would suggest wandering down to Albert Park and check out what they are sailing. Sailing on Albert Park is a little different to sailing anywhere else. The Mirror dinghy on EBay may suit but it is not on a trailer. The Taser would suit too but is a lot of boat unless your crew is a lot bigger than you. Last thing on Albert Park would be on off the beach catamaran. Buy similar to what the others are sailing.
