Which is why the Laser 28 is so intriguing to me. You've spoken highly about it many times before... and there is one for sale, or is it sail...

Wife hates me right now.
Has it already been two years? Ready for your new boat already? What happened to the J92 idea?

j92, too costly for a soggy balsa deck. Haven't seen a layup on a J that has lasted. Maybe I've only seen poorly kept ones, but they churn my stomach, both beautiful and poorly laid up.

I'm sure you are right. I haven't done any analyses of sailboat masts myself, and my comment was based only on a visual appraisal of the expected behaviour.

Cheers!

The only dumb question is the one that you didn't ask because you thought it would make you look dumb.
