Also it is part of the Offshore Special Regulations, MoMu0,1,2 section 4.26.2 d. You may have a very deep reefed main, in lieu of a storm trysail. Although these are designed for offshore racing, they are rules and parameters built over years of what works and is safe. Excellent guidelines for use by cruisers as well. Well worth reading. https://www.sailing.org/specialregs From: CHARLES SCHEAFFER [mailto:[email protected]] Sent: March-23-19 7:16 PM To: [email protected]; Josh Muckley Cc: john sandford Subject: Re: Stus-List Second Reef Point on 33 MKII Hi John, Curious what model boat and where are you sailing to justify four reefs.

Viz. Wind Pressure in Pounds per Sq. Ft. = .0053 x (Wind Speed Knots squared) Works fine up to 40 knots, (when the 4th goes in) haven’t tested it further yet. From: Josh Muckley [mailto:[email protected]] Sent: March-22-19 9:52 PM To: [email protected] Subject: Re: Stus-List Second Reef Point on 33 MKII Not specific to 33 mkII but it is my experience that most slab reef points are equal distance from one another and the boom. About 1/4 of the height of the sail per slab. If you find that the boat is uncontrollable in heavy winds with the first reef then either a second reef or no mainsail at all would be in order. Your rigger/sail maker should be able to give some ideas. If you have or plan to have a bat-car system, or a strong track system the placement of the second reef will have to take into consideration the stack height. Penents/dog bones may be required to reach the reef horn. Boom height when reefed is going to be a consideration for the clew ring placement. Again all questions which the sailmaker should be discussing with you.

I do have two reefing lines in my boom so I can accommodate a second reef and am thinking of having one installed. My questions are: 1. Do other 33MKII have as second reef? 2. Are they beneficial? 3. Where on the mainsail is the upper reef? I race on Lake Michigan and we have had some nasty winds the last two years.
