Re: The Death of the Ketch ?

Re: The Death of the Ketch ?

This is what i remember as well,....another case of the racing rules designing our vessels rather than 'mother ocean'.

Don't quite understand you here. Don't the shrouds carry a lot of the side-side forces?...particularly with very wide spreaders (tradition ones, not the fore-aft one you refer to (that I term a...

Are you taking about reading;
1) a 'website',
2) or a particular forum posting,

Re: Vertical Backstay

Several thoughts there.
1) In the first place the shortest distance for that major aft masthead backstay to assume, particularly in its highly loaded condition is the straight line over the aft...

Yes the monohull version looked a little more 'weird', but I was really looking forward to combining that rig's low leeway inducing force to the asymmetrical twin keels on the hull. I really think...

Re: The Death of the Ketch ?

I was also impressed with her sail shapes and cuts, particularly as she is carrying two in-mast furling ones.
