My other boat is a Catalina
270 which I sail on Lake Tahoe, NV, USA. The boat is occasionally rented to qualified visitors. One of the renters tried to raise the mainsail
without shaking out the jiffy reef. The reef line untied at the hook and disappeared inside the boom. There is a double block inside to connect the reefing line/reefing hook loop to the the reef outhaul/ downhaul at the clew end of the boom.
Has anyone disassembled a boom on a Catalina
270 to get to the internal tackle? Suggestions?
