A week or so ago, I downloaded some great pictures from funtigo that someone had submitted on their jiffy reefing install. I am unable to locate those pictures on line at funtigo at the present time so I don't know who submitted them. I am preparing to install this system on my M15 and have a question regarding the installation of the cheek block on the boom. It apears that it was attached with rivets and my question is what length rivets are needed and what diameter rivets to get. I suspect 5/32" with a grip length of 3/4" or 1/2". If the person whose pictures those were could email me off line at: seawitchlj@yahoo.com, I would really appreciate it. Sailing the Great Salt Lake single handed without having the ability to quickly reef is just not a safe practice. Thanks in advance for your assistance. Time for a cool change! Sandra(Seawitch #617)
