Raist the Mast Fast
Posted: Tue Sep 27, 2011 10:22 pm
Having tried the various methods to make mast raising quick, such as quick-release lifelines, levered forestay pin (reverted for safety reasons), and numerous other quick-release hardware changes, I thought I'd post on the one that really has the biggest impact. I didn't invent this mod, but a few people have asked about it in PM so I thought I'd post a recap.
Changing the spreader bolts to quick release pins and taking the spreaders off completely while trailered does more to reduces setup and take-down time than any other modification I've done, by far. The struggle to move the mast from the bow pulpit to the mast step literally becomes a walk on deck--no issues, no struggling to make the last few inches, no tension anywhere. There's no struggle to get the spreaders above or below the lifelines, no "managing" stays as you move the boat forward and getting hung up on everything as you go forward--no nothing. Just move the mast, then put the spreaders on, and lift.
Granted, you do need to be careful to put the spreaders on right-side up, and make sure that you've not got the spreaders on the wrong side of lifelines or halyards, and put the quick-pins on such that they are right-side up when raised. The speed difference for me goes from 15 minutes of struggle to maybe three minutes of no worries other than attention to detail.
It's also about the simplest mod you'll do: Replace the two bolts that hold the spreaders to the "spreader holding thing whose proper name I do not know" with 1/4" x 2" wire quick pins from Home Depot:

Easy peasy. When you take the spreaders off, I toss the spreaders, stays, lines and sheet ends down into the cabin and close the hatch, which keeps everything perfectly fine while trailering. I move the lines and stays to the edges of the sliding deck hatch to move it over the companionway hatch when closing, and will likely shave a 1/4" corner off the top sides of the companionway hatch to make that easy. When you setup, just open the hatch, move the mast, and put the spreaders on.
These pins are zinc plated and as such will corrode faster than the aluminum spreaders and the stainless thing mentioned above, which is what you want. Inspect them as you use them and prepare to replace them every few years if they look like they need it.
As with every modification from stock hardware, you should evaluate the risks yourself. Others will present their well-formed opinions of this mod, and as with all risks, you'll need to decide where you are on the spectrum between "I don't leave the driveway" and "I don't stop drinking till I get to Catalina".
I've been sailing this way for months with no issues--the pins have never ridden up at all, under any circumstance--but I have yet to sail in winds above 12 knots (Just don't have those here in San Diego often). Because the spreaders are under hundreds of pounds of tension pushing directly against the bolt when the mast is erect, it is my opinion (and only that) that the force required to move them well exceeds any force they will be subjected to, so I personally have zero concerns about this mod. If a pin did fail by riding up past the retaining wire and disengaging, the spreader would push farther in (it cannot pull out while under tension), the mast would lose all tension, and you'd have to drop sail to avoid shock-loading the mast foot. But this is fixable even at sea, so keep the original bolts in your rig box for injury rigging.
If you have any questions, post. If you do this and like it, post. If you think this is dangerous, post. If you know what the thing that the spreaders fit into is called, post.
