Todd is correct. Every boat, NOR or not, should have individual harnesses, jacklines, lights for each crew harness with whistle; mandatory life jackets at night; MOB poles with strobe/drogue/life ring; EPIRB; mandatory paper charts; GPS; Parachute flares/handheld flares; radar reflector. Mandatory knife for each crew as well has a cockpit knife. Engines mandatory with a fuel range of 2x the width of the lake. Extra battery for when your lights go dim from use. You don’t have a way to charge your battery. If you lose your rig..cutters and tools to toss the rig quickly! VHF base unit and a separate handheld.
On another note: two mains are not legal in most rules. Reef points..you should rig them if you don’t usually use them. If you have none…they can be retro’d at the sailmaker.
Look at the equipment necessary for the Chicago Mac Race. You are one thunderstorm away from hoping your crew stays on board. The capsize in the ChiMac last year was spotted ONLY because of a strobe. http://www.racetomackinac.com Look for the documents..MSR for monohulls. Help from the Coast Guard will be a couple of hours if you are lucky. Other boats may be in as much trouble as you are.
Last…cell phones with a link to weather radar.
Hate to throw water on equipping your boat minimally, but offshore at night is a survival trip. I agree again with Todd…to reduce safety for a minimal stability boat (103 is min for ChiMac) that rates around 105 stability at best, is questionable. Especially with no reef points. I trust the Olson as much as anyone. But the responsibility to make the crew AND myself have the best chances in the worst case scenerio is mine. I do question the organizer on your waivers…minimal night gear is a must.
