Hull beam is around 100 cm. Waterline length is around 34 ft loaded.

Just a reminder, this is a "souped" version with nearly 50% more sail area in the mainsail, good laminate sails with 8 battens in the main and a rotating wingmast. Spectra rigging. Bowsprit etc...

Hi, Alan, So, loaded a DL of about 148, on a 34' DWL. If it's hull beam is 100 cm, though, it has a rather slender 10.36 hull length / beam ratio.

I noted that you had a good rig, and what I have read about rotating rigs makes them sound very good indeed. Is your mast fairly airfoil shaped?

If you must have standing rigging, I like the idea of Spectra-less metal to fatigue. I have seen many a ss shroud and stay with broken strands where it enters the swedging.

I haven't looked at SA/D yet in this thread, but that is also of interest. The original mainsail would have been 430 sq. ft. with a total area of 731 sq. ft., so 925 sq. ft. now, and your SA Disp loaded would have gone from 21.9 to 27.7.
