John- I never felt the need to tighten the forestay that much; I liked it loose enough to easily hook it up by hand with no adjusting needed. it sails best with a bit of slack, just like most boats with that type of rig. Tune it (MAST RAKE) for best speed upwind and the slack will let the mast move a bit forward off the wind. jerry ________________________________ From: montgomery_boats <montgomery_boats-bounces@mailman.xmission.com> on behalf of John Schinnerer via montgomery_boats <montgomery_boats@mailman.xmission.com> Sent: Monday, October 12, 2020 9:09 AM To: montgomery_boats@mailman.xmission.com <montgomery_boats@mailman.xmission.com> Subject: Re: M_Boats: Forestay Adjusting levers? A quick release is just that, if that's what you're talking about - a way to quickly provide or remove slack. When it's "open" you have plenty extra slack, for whatever you need slack for. When it's "closed" you have whatever tension, heavy to light to slightly loose, that you set the adjustment to have. So yes to your question as I understand it - there's no requirement that a quick release lever type device have high (or any) tension when "closed." Just make sure it has a locking pin so that when it is closed, if the tension is light or slightly slack even, that it won't flip open by itself. cheers, John On 10/12/20 7:25 AM, Alex Conley wrote:
Thanks Tyler, but can't the tensioner simply be set with the forestay at the same tension/length as you’d do by hand to keep the rig loose (it’s got a pin to lock it closed, so I wouldn’t expect it to open)? Or is there a reason it would always over tighten the rig?

This might work on an M17, but the M15 is designed to have a slightly loose rig... using a tensioner like this will prevent the center of effort from raking the mast aft upwind automatically as it should, and could damage the cabin top.
I re-rigged my M15 using 316 wire and Hayn Hi-Mod fittings, which can be done at home with just a crescent wrench, and allows me to re-rig every few years by just buying new wire. For stay adjusters, I used 10 hole Hobie Cat shroud adjusters like this: https://westcoastsailing.net/hobie-shroud-adjuster-10-hole/
My Spyderco Salt (a gift from Sal and Gail- Thanks!!) slides right into the shroud adjuster, and makes a great handle for adding a small amount of tension when putting the pin in... no need for a leveraged adjuster.

Alright Dave, here’s a question related to one of my winter projects. I’ll be replacing the stays (friend’s story of loosing mast first day of a San Juan cruise convinced me new wire and the peace of mind it would bring are worth it). I’ve contemplated adding a adjusting lever to the forestay to make setting up and tensioning the rig even easier. Curious if the M boat hive mind has any opinions on a) whether a forestay lever is a good addition on an m15, and b) if there is a specific one folks would recommend. Here are the two that have caught my eye:

Thanks for any feedback!
