Lester,
I am not at all sure if I would recommend shortening the Nonsuch’s original mast by chopping it off in the lower end. The bending moment at the partners, needed to heel the boat over to 60°, is the same, whether you use a long or short mast, as long as the boat is the same. (same beam, weight and ballast).

There is an alternative to spilling winds by bending the mast: Ease the sheet and/or drop a few panels. If you on a fine Sunday come pottering downwind, and don’t notice the grey-black wall of a thunderstorm coming up behind you, you can still save the day by just dumping all but the two top panels. Makes you feel lucky you have a junk rig...

PS: BTW, the sail I sketched for you is just about the same shape as the sail of a former boat of mine, Johanna (SA=48sqm, B=5.80m, AR=1.87). She worked well with that rig.

 

 Arne,

 Thanks for your comments; that's what I like about this JRA site, there are always  curious inquisitive minds at work using intuition and imaginative creativity. Your efforts with the sailplan were Awesome!

 These NS 30 boats are known for having a capsize ratio over 2.0 and I'm thinking that less sail area and a shorter mast may be the E-ticket; it even introduces the possibility of keeping the lower mast section as a tabernacle and keeping the top tapered section for spilling gusts.....hmmmm.  I applaud your effort.

Chris,    Thanks for the reply. The 'list' was my first stop in searching. I'm sure it would be considered blasphemy to ask on the Nonsuch site; so I intend to avoid the drama. Thanks for your info again.

Cheers,

Yes, one has to develop a thick skin when converting to junk rig.  I have to confess to being completely fed-up with the negativism I encounter when mentioning the conversion of very ordinary, plastic boats to junk rig.  You'd think it was an original Fife teak and mahogany classic from the response. 

And that old chestnut - but it won't go to windward.  Sigh.

However, the good side of this is that junkies become a good community, simply because it's so nice to be able to discuss rig ideas and issues with people who understand and empathise with what one is doing!

I'm not aware of any, and there are none on our list of boats which have been converted, although quite a few Freedoms (similar original rig) have been converted.

If anyone else knows of a Nonsuch conversion please let us know so we can add it to  the list.
