By sheet winches on top of the house, you mean like you would do on a M-15 (if you wanted winches) or a Santana 20, or the new Sage? The value is that you can winch in after a tack from the weather side instead of having to get your weight off to leeward. On a boat that has the jib sheeted inside of the shrouds (on the house top) it's a no-brainer to put the winches (also the wenches) on the cabin top, even tho it moves the weight a bit higher it's worth it. Cabintop winches would also work for a spinnaker but you would need to have clamps for the sheets so you could release them after the chute is up; also the halyards. Is this what you were asking? jerry ----- Original Message ----- From: "Howard Audsley" <haudsley@tranquility.net> To: "For and about Montgomery Sailboats" <montgomery_boats@mailman.xmission.com> Sent: Thursday, July 07, 2011 12:54 PM Subject: Re: M_Boats: Whisker Pole Installation
Along these lines, what is the purpose of the sheet winch on top of the cabin? I've always assumed it was "chute" related, but wasn't sure. I've only used it for adjusting the tack on an asymmetrical spinnaker and will also wrap the topping lift around it, but isn't needed for that.

3' is a good do-more measurement on most boats. Best is to mount the ring on a track with the middle about 3'. This is actually a measurement for a spinnaker ring, but I've never had a problem with it for a whisker pole, and ikf you cdan move the mast end of the pole up or down you can control the twist to a certain extent.. A 4X 8 pole should work for a 17; that's what I have for my Sage but I really can't remember using it.
On spinnakers, most racing rules (PHRF, etc) restrict a spinnnaker to 180% of the J, and the pole to no longer than the J. A lot of small trailerables that aren't concerned with no stupid rules will reach better with a 200% chute, and they will be better in a drifter period. The big deal about keeping the spinnaker pole level is simply so that it will project out further, keeping the slot between the main and the chute more opener.

Well, Jerry, how high up on a 17, If I might ask? Maybe the 6-12 pole would be more appropriate, but I don't have the mast up to see if the longer pole is necessary.
Thanks, Tom Jenkins

3' up from base; Forespar 4-8 is about perfect and will even work for a 150 or big drifter.

Hello All, Can anyone tell me at what height on the mast the eye should be installed on a M-15 to use a whisker pole on the factory jib? How long a pole will I need? .With thanks.
