Kemp Boom bits.

Does anyone know where I might find one of these? Boom diameter is 4 ins. Just the piece that the main sheet and topping lift attaches to.

I'm pretty sure you won't find one. Slab reefing has been the norm for around 30 years and Kemp masts are long gone. Classic Marine might have something similar as they do a lot of older rigging parts but even if they do, it won't be cheap. Selden list part for my (Kemp) mast and boom under "Old" parts but nothing like your fitting.

I had the same part fracture right through a dozen or so years ago. Wouldn't have trusted a used part, even if I could have found one. Considered having one fabricated (it had long been converted to slab reefing so wouldn't need to allow the boom to spin). Then bit the bullet and bought a new boom from Z-spars for surprisingly reasonable cost.

Any good?

If not I would write to ever rigger you can find asking for help and hopefully one of them will be replacing a boom so have the old boom available.

Got exactly the same boom end. Mine cracked so I had it welded. If that's your problem welding sorted mine out fine although I had to take the whole boom to the welder as the end was seized on. Obviously the nylon/teflon washer/bearing that allowed it to revolve melted but I have slab reefing so no problem.

If you do not need the boom to rotate for roller reefing, you can simply secure the sheet to a bail or even a lashing around the boom.

I got a new bit cast many years ago at a local 'foundry' when they were casting some aluminium bits. The old part was used to create the mould. There was another post like yours a few years ago on here I seem to remember with the same problem and the person ended up creating a s/s 'bracket' on the end.

Yikes what a horrible piece of device that is. As said if you do not need boom rotation (and even if you do you should consider slab reefing) then topping lift can be achieved with a saddle riveted or bolted to the top of the end of the boom. Main sheet attachment can be done with webbing or a dyneema strap. Outhaul can be done with an embedded sheave box on top of boom. Well if was me I would redesign the whole boom end. Aim for minimum protrusions that might exacerbate a head injury if boom hits you and for minimum weight. (less drama in a gybe.). good luck olewill

Saw this today http://www.ebay.co.uk/itm/GIBB-solid-Bronze-boom-end-fitting-suitable-for-roller-reefing-mainsail-/232303855330?hash=item36166386e2:g:Y34AAOSwIWVY80u3
Would probably need to machine an adapter to fit.
