Is forestay shackle a DIY or replacement job?

Postby DuncLlew » Mon Dec 28, 2020 12:36 pm

Hello
Storm Bella has caused some mayhem in our dinghy park and my mast came down breaking the forestay shackle (I think that's what it's called - picture attached). It's obviously a high stress area, so do I buy a new one from Hartleys or simply replace the shackle? I couldn't see one on the Hartley's website. I have whipping twine, but the join looks more thorough than that.
And there's also a small bit of damage to the gel coat - Hartleys have Teroson Gel Coat Filler on their website - is that the right stuff and colour? I've put tape over it to keep moisture out. Thanks.

Hi Duncan

Sorry to see the damage - I haven't checked my boat for a few months - hope it's ok.

I think the block is a standard Allen part. If you are particularly concerned about strength you could use a 'wire block' (block for wire). Check the breaking strength before you order. I have made cascade kicker assemblies with wire blocks at mast and boom ends where the loading is highest.

I don't know about the gelcoat repair stuff. Check out Pete Vincent on Youtube (West Country Boat Repairs) based at Lydney Glos. - or call him. He is very helpful.

Best regards

Pete

Hi Duncan,

Regarding the gelcoat I'd recommend giving Hartley's a call, they'll have a record of the colour that was used and be able to supply a match. Most hulls are an off white colour as standard but worth checking as my old boat was brilliant white. It's worth noting that its rarely a perfect match due to the batch making process and the colour fading that occurs due to weathering/age.

When you come round to repairing make sure that the weather is warm enough. I can't remember the exact temperature that is required but I always work off 10C+ and in the garage/club hanger if you're able - as Pete mentioned there's loads of useful hints & tips on Youtube.
