My current and only boat is a modified Taipan F18 from 1999. The heavy-weight front beam was replaced so that the total weight is now about 160kg (I'm not doing regattas ...), the mast was exchanged with a Tornado mast - so in total it's quite a bastard . And one of the fastest boats in the local club ...
Season ceased over here (northern Germany) end of October, NO SAILING before early April.
