Re: [bolger] Re: Mizzens
- Armchair sailing here, with my Micro's trailer locked in a glacier of ice, I'm thinking that if you tried double sheets on a Micro you would not have a good sheeting angle on the starboard sheet, unless you did put on a conventional boom and so could fasten the sheet closer in to the transom. I think I'd rather have the single sheet, and if I want to force the mizzen to windward when in irons or nearly so, stand and push the spritboom by hand. ---Mason----- Original Message -----From: robertsmmeSent: Friday, March 05, 2010 4:49 PMSubject: [bolger] Re: Mizzens
Nels and all,
This is a question I have been asking myself. I was wondering about putting two sheets on my Micro's mizzen this year to see if would help me to tack by allowing me to pull the mizzen to the windward side during the tack. The only concern is that with two sheets I am not likely to get the balancing behaviour I get with the single sheet on a Bumpkin. In that mode I can steer the boat when travelling anything from a broad reach to windward, simply by pulling on the mizzen sheet. This is because it brings the heading into the wind when pulled in tight and off the wind when released. You can in fact tack a micro with out touching the tiller simply by pulling and releasing the mizzen at the right time.
I have also wondered about putting on a 'normal' boom so that I could reef the mizzen by rolling it around the mast. This would probably require the bumpkin to keep the boom down, which with the sprit boom you do not need to do.
I do not believe that the position of the bumpkin makes any difference to the handling. If you look at Gary Hoyte's Balancing rig you will see it manages well with the sail off centre, granted his mast is not.
In conclusion, double sheets will give you maximum control of the mizzen, which if you can manage all the lines will give some benefit and will also save you from having a 6 foot pole out of the rear of the boat. The other issue with the bumpkin is that I find that off the wind I can easily get a tangled sheet under the bumpkin if I should gybe without pulling in the sheet.
What I would say is that I would be reluctant to sail without one now. I love the control it gives. I love the relaxed feeling it gives me when sailing and most of all I love the unconventional look that it gives.
Nels says “That is exactly what I was wondering about! With a single sheet, you can
only snug up the mizzen sheet to line up above the boomkin/bumpkin or
loosen it off the wind but you can't pull it to windward to kick the
stern through a tack.”
If you think you need to backwind the mizzen to tack I say you aren’t letting out the main at the right time. Accelerate into the tack and then slack the main. Trying to keep the main in during a tack like a fin keel/drop keel/daggerboard boat is fighting the design except in strong wind. You get the same problem of losing speed and gaining leeway if you haul in the main too soon after tacking.
