In our case, we're much more likely to get thwacked in the head by the sheet blocks on bails hanging off the bottom of the boom than the relatively small cheek block (wood cased) on the side of the boom. You can see the reefing line hanging down from the cheek block in this photo. It's the nearest one going forward. The far one going forward is a preventer that is clipped onto a padeye on the bottom of the boom just aft of the sheet blocks/bails.

Still, as high as your boom is, there is a unique gravitational phenomenon between my head and cheek blocks. I'm sure I'd still get smacked. And those bails? yeah, those too. Nice shot btw, where is that?

That's just outside the Golden Gate bridge on our first ever trip up from San Diego to the SFBay in 2010. Wing on wing on wing on wing (Main, fore, staysail and jib all batwinged out) we were running into the Bay at 12.5 kts SOG (3 kts was current) and with our 47' waterline that was pretty good going. We had passed everything downtown and zipped around by the financial district before we ever knew what was happening.

Surprisingly I've not been hit by those bails or any of the crap hanging off the boom--and there's plenty to be attacked by. When the boom is centered, it is only 6'5" above the cockpit sole and the bails are a threat to forgetful folks for sure.

Re: Attaching reefing line directly to cringle cuts line aloft

Of course! Well that's embarrassing, I was just at the beach there watching the kite surfers a few weeks ago. Though it looked familiar. Wow, still 9.5 knots, a schooner.... can I have a ride on your boat? I'll bring my helmet.

Entirely dependent on whether you are just a danger to yourself or do you get others involved in the pain?

UH, yeah, usually just myself... I graciously provide everyone with the example of what NOT to do, for all the training sessions

Looks like the previously discussed problem - the angle doesn't balance the load correctly between leech and foot. The direction of tension should be between the two webbing straps. Rigged that way, it is all below the lower one.

Look at the photo again. It is not hoisted in the photo, so the lines lead aft to the boom, and end of boom. This takes out much of the friction in the cringle and lets the line articulate.

As rigged, it looks like it should not lead directly to the end of the boom. The load vector should be down and back more-or-less equally. So--when you reef, the reefing clew is further forward on the boom than the regular (end of boom) clew and leading the reefing line to the end of the boom won't provide the correct load--you have to have a line around the boom, a cleat, something that prevents that load vector from being too horizontal essentially. Was there a pic of the boom showing a cheek block, line, or similar control?

Thanks!

... so I really want to have something in place to make it quick and easy, but there's not a way I see with the way the foot of my main lives in the boom to make that happen with a permanent line around the boom.

Whoever made the sail with a bolt rope in the foot should have also installed grommets or slits in the foot to allow the reefing lines to pass around the boom. Not needed with loose footed mains. All mains I've owned have had this provision.

Ideally you can run the reefing lines from the end cap of the boom. Adding blocks or anything with sharp edges to the side of a boom greatly increases the chance if a life-threatening injury during an accidental gybe.

Cheek blocks need not have sharp edges though they too often do. I believe Don was referring to his running into the unexpected protrusions (perhaps even while the boom lay in its gallows) rather than them running into him.

Round the buoy racers often seem to place their bodies in harms way as they compete. OTOH There is little reason for casual sailors or any cruisers to habitually do so. Do you think that one must sail in such a way to allow oneself to be in the way of the boom regularly? Unless racing, I cannot think so.

HA! Yes, and I have the scars to prove it! But in my own defense, I was wearing a large brimmed hat so my peripheral vision was impaired.

That's a common problem--put on the Sun hat and protective equipment and the next thing you know you're off your game. 😚
