Boom end clean up

There's a layer of corrosion between the paint and good metal, so if the paint is dissolved, burned off, or mechanically removed, I still have to remove the corrosion. You can see it in close up picture of the fitting. it's a white layer between the blue paint and shiny metal.

Are you sure it is (was) corrosion? There's often an initial coat of an etching primer applied when painting aluminum...

I found a stainless bolt lying on the deck today beside the mast. After a panicked search I found that it originated from the boom end fitting where it attaches to the boom. Thank goodness it wasn’t from higher up! All four of the bolts were loose and two of them had worked so much that the threads in the boom end casting are buggered and they won’t tighten. I had previously overdrilled and tapped some of the old holes. There are many old holes, indicating an ongoing problem, and apparently my fix was no better. I’m not sure what to do except oversize the holes once again and maybe use Loctite this time. I used lock washers before. I plan to pull the boom this winter to address this and some other small problems (sail stack pack slugs have broken). Any thoughts on how to manage this?

@bigd14 - Doug, Are the bolts I circled in magenta the ones you're talking about? (Seems obvious now that look at it, but I already got this far.) Could you install some kind of threaded insert in the aluminum casting? You could have the holes welded shut and redrill. It would need a really good weld job to have good metal. Maybe weld the holes in the boom and redrill those to? Massive rivets?

Yes Jeff, those are the culprits. I like the idea of the inserts, thank you. After thinking about this more I am also considering through bolting or even attaching an L bracket to capture the edge of the casting and hold it tight against the boom. This would be attached to the through bolt that holds the sheave assembly inside the boom and another through bolt that passes through the inside collar of the casting. The L bracket is probably overkill, but overkill should have been my middle name.

That fitting on my boat is secured by only two big self-tapping screws. There're just there to hold the boom onto the sleave of the gooseneck, no real mechanical connection intended.

Is there play, resulting in gradual loosening? Perhaps a shim would help. I don't think the thru-bolt needs to be involved.

Though bolting seems like a good solution. If you have room with the foot of your sail, you might consider cutting off the front 1" of the boom with all the holes to start with a good material. Locating the existing holes from the gooseneck fitting in the boom might be tricky.

All good ideas....

Like Christian said, there shouldn't be any play between the two parts. The screws should only prevent the end fitting from being pulled forward out of the boom. So if you have play in your slip-fitting between the two parts, I'd fix that first with shims.

Since you have multiple holes, and they've already been enlarged, I like your L bracket idea with the through both attachment. It would be even better if the front prongs of the L bracket were welded onto the end fitting.

If all that fails and you have this problem again. You could resort to next idea of cutting 1 in off the front of the boom and starting over.

I believe there is, but I am not sure why that would be. Perhaps this particular casting shrank a bit and was installed anyway. Shimming is a great idea.

Yes, great idea also. It would certainly look better and give more meat to work with. I think I have plenty of room.

I’ll revisit this winter when I can pull the sail and boom and it’s rainy and cold. Thanks for all the ideas. There never seems to be a shortage of projects. I’ll post whatever fix I come up with.

Had a similar issue with my boom. I then realized there was also a bolt in the bottom of the boom that prevents the movement that causes the issues. That bottom bolt had fallen out at some point, once I replaced it the movement ceased to be a problem. Check if yours is still there and tight.

Dear Christian,

My name is David Eckert. We connected a few years ago on the Ericson Owners Group when I bought my Ericson Quintessence, which I renamed Salty Dog.

I saw your pisode a few months ago bout your devastating loss in the fire. I truly understand what that feels like. I lost my home in the Bastrop Complex Fire, the largest wildfire in Texas history. That was more than a decade ago, and it taught me hard lessons about life. Now at, 61, I’ve faced my share of challenges: a major health scare last year, a triple bypass, heart valve replacement, and then my wife underwent double knee replacements. Because of all that, we had to part with our beloved Salty Dog, a sister ship to yours, the same year and model, an ’84 381. Sailing dreams are still alive, but for now, they’re on hold.

I’m writing today not about sailing or boats, but about books, and about someone we both know well.

I want to collaborate with you on a project that deserves to be told on the biggest stage possible. A project to bring the legend of Joshua Slocum out of history books and into popular culture, and eventually, to the big screen.

I’ve written a screenplay titled “Spray.” It tells Slocum’s story: from his harsh boyhood in Nova Scotia, to a runaway schooner cook, to becoming captain and part-owner of the Northern Light after sixteen years of relentless work at sea. His life was an epic rise and fall that built toward the crescendo of his legendary solo circumnavigation of the globe.

As someone who grew up in California, I remember passing Joshua Slocum restaurant in Newport Beach, it was a name that always sparked curiosity. Today, I want to make sure the man behind that name is remembered by a new generation.

I’ve prepared a visual “look book” that lays out my vision for the film, but I would never impose by sending it without your invitation. The screenplay is complete, and the novel is already 26 chapters in, about halfway there.

You bring far greater sailing experience than I do, and your screenwriting talent is something I deeply respect. As an aspiring screenwriter, I would value the opportunity to learn from you and collaborate on a story that I’m passionate about. If our generation doesn’t bring Slocum’s tale to life, his legacy will vanish like his old Newport Beach restaurant, a memory few will recall.

Every great project starts with rough edges that need to be smoothed out—like a fine coat that must be pressed before it’s worn. I believe this is that kind of project.

Will you partner with me to tell Slocum’s story anew for a new generation?

Thank you for considering this.

With respect and anticipation,
David W. Eckert
