Wish this thread had been going a few weeks ago! I have a fiberglass hard dinghy that we call "The Dinghy of Death" because it is always tipping me out - even when reaching to grab the jetty! The options for story a dinghy on a C28 are limited and have long been contemplating one of those Porta-Botes, but ended up buying a Sirocco 220 AirHull from the Sydney boat show the other day. The inflatable bit is good as it can be stored down below when crossing Broken Bay, but the rowing abilities of rubber dinghies leave a lot to be desired. Will have to fork out more $$ for a small outboard - plus the petrol, (premix) which is another thing aboard I don't really need.
The English method of hoisting the nose of the dinghy up to the pushpit rail and leaving the two stern bits to trail in the water looks like a good idea, which means that you don't have to deflate the dinghy and store it during the Broken Bay crossing, where you get a huge swell on most days and if you tow the dinghy it could tip over and fill with water, or worse, end up in the cockpit.
cheers
