Hi Dave

The 18HT is a great boat and for 4k I would'nt think too long. In our class in Switzerland ther are some, that use a smaller main with 16sqm when they sail alone. They say it sails like an A-Cat then. I sail my 18HT with the big main sometimes allone until to 4 Bft (16kn) and I'm not a heavy guy with 68kg. But for sailing allone, I would prefer a smaller main. For righting the 18HT allone a waterbag is sufficent for me.

The RIBA mast on the 2002 Javelins is strong and still flexible enough to trim the main nicely.

Good luck with your choice!
