boome end1.jpgboomeend2.jpg

ive just notice on the end of my boom that the part where the block goes to hold it down is badly worn . how easy is it to source a spare part for these booms?
I could imagine sailing and this wearing right through and snapping then the boom would just fly right around ouch.
 
I had similar and replaced it with something like this:

Barton Fixed Pad Eye

Slid into the channel on the underside of the extrusion and fitted with bolts and a backing plate, it has held up ok for years.
Instead of replacing the casting with rivets I tapped it for screws which has proved handy. According to Selden that cast loop should not be used for attaching the mainsheet, what it is for I am not sure.

thanks did you remove and re fit the end piece to attach the barton eye. ahhg i get it you removed and re fitted with screws instead of rivets.
 
Totally different fitting

I had a flange welded to our aluminium bowsprit and the flange had a hole for a shackle that secure the dyneema bolt rope of an unstayed headsail. The hole should have had a stainless sleeve - but this was not supplied. The hole wore, I noticed it after a couple of years, - much worse than in your photo. I complained to the supplier and they simply took the bowsprit away and welded the hole up, re-made the hole and inserted the stainless sleeve. Its been good since - maybe 20 years.

Take the fitting to someone who will weld it up.

All sorts of other options. You may in fact find it difficult to remove the whole fitting. You could fit a bail as in u shaped ss metal that rivets on sides of boom to sling under the boom for attachment. Most other options apart from re welding the metal of the hole will involve sheeting from a point further forward than end of boom. Shouild not matter much. My main sheet attachment is a long way further forward and consists of webbing going right around the boom sewn together through a ss fitting. Has lasted for years.
Yes you did well to find the imminent disaster. I had a ss saddle on the bottom of the main sheet wear through and let go. it was right on the start line in a crowd of boats. Being a little boat I was able to reach up and pull the boom back until we could lash it with string. yes all a bit scary. ol'will
 
the sailing brother show you how easy it is to fit a new boom end (assuming you can find the correct sized new end)

Once you've welded and redrilled, try using a soft shackle there instead of metal on metal - then it won't wear through again.

+1.
Another spot where the same thing is likely to happen is the anchoring point for the kicker block on the mast foot (on older Seldén deck stepped masts).
As seen in this photo the band type shackle has ground away quite a bit on the aluminium casting over the years. Now replaced by a soft shackle.

As per others a general engineering place that can weld aluminium. I have had recently the same problem with the bit on my kemp boom. Years ago I got one cast as a spare.
I like the idea of a soft shackle to restrict wear on the fitting.
 
I think i will be ok as just been the boat and noticed two sliders one is for the kicking strap and the other spare . ive slid it all the way to the end and looks strong enough.

(y)Result.
That looks like the boom slider they used for general stuff like reefing points, I have very similar things. As LadyinBed has pointed out, the screw is designed to mate into a hole drilled in the boom and may well not hold by friction alone.

Seems well up to the job but it's worth knowing that the original main sheet sliders were secured by two screws and were beefier.

As previously mentioned, Post # 6, - it is common place now for the main sheet to be attached to a tape loop/band that is round the complete boom. The tapes are commonly 25/35mm wide - which spreads the mainsheet load. You could make the loop yourself using off the shelf nylon tape and sew it together, by hand, using dyneema braided fishing line.

We have a newer Selden boom. The end casting (at both ends) is secured with fancy Alan key bolts which for some reason are security bolts. They have a recessed hexagonal slot in the head with a little pin in the centre negating their ability to use a conventional Alan key. Our outhaul failed, in the middle of nowhere - and we had not been supplied with the appropriate key :(. I was not impressed. . We bodged and took the boom apart (the outhaul is quite a critical component :) ) and replaced the outhaul - but check your boom and the method of assembly. On the underside of our boom is a slot, the length of the boom. The slot is equiped with slider 'eyes' for the reefing lines - sort of like pad eyes - pretty chunky., cast stainless They are are located and secured with those same security Alan bolts.

I note the comment that Selden say the offending hole is not to be used to attach the mainsheet - which makes me wonder why it is there at all - as it seems the obvious place to attach a main sheet. If its not to be used for the mainsheet - why have it there (to be misused) ? The end casting on our newer boom has a 'thing' like a handle or hand hold - the use of which - no idea. We have had tape for the mainsheet from the outset.

Those security alan keys are available in the UK. Draper used to do a set for various types of 'security' bolts/screws.
 
I get one of these today so fingers crossed that it will fit in the slider and i will drill and tap two screws to secure it.

I know - there are a variety of these Alan security devices, different shapes etc - my complaint is/was - if you are using them in (what I would call) an everyday application you should supply them, the keys, as part of the kit.

We were sailing up the east coast of Tasmania, towns have a population of a few hundred, safe anchorages are few and far between (and not near towns) - what precisely does Selden expect an owner to do. Yes - blame the installer - not good enough in my book - I criticise both. Why, precisely does a boom end need security bolts?

I think this will do the job took me a long time to grind and shape it to fit in the slot but it fits snug now. I will tap both the screws into the boom.

Did the wear come from sailing, age or wear while moored? I secure my booms (and anchor) to stop any movement when moored and stop wear on boom end and gooseneck fittings. On a previous boat kept on a swinging mooring I had significant boom wear from rolling.

Definitely right there. I have had a track and traveller car wear out from rolling on mooring. Now I disconnect topping lift and drop the boom on to the cabin top. No movement although some helpfulls on occasions have told me my boom has fallen down. ol'will
