Hi All,
I was looking for some recommendations on the attachment point fittings that would be mounted on the boat to be able to "tie off" with the body harness lanyards. There seems to be a lot to choose from but some look very light and cheap.
I think there are about 5 or 6 of them.
Also, I would think it would be a good idea to have a backing pad either of plywood or stainless steel ( or both ) to reinforce the area. I believe they are all in locations where it is only 1 layer of plywood.
Thoughts?

Haven’t started looking at these yet, however I will definitely be looking to ensure I have some good backing plates in place. If you are lumping a sail around and fall from the opposite side of the boat that’s a good fall and weight. I will also be looking at having a long and short lanyard on Lifejacket.

My thinking was yes to ply backing pads for sure (maybe 3-5x width and length of the bolt pattern of the fitting?), and probably a stainless pad as well, rather than just washers behind the nuts. 3mm 316 stainless flat stock at 100mm wide is relatively cheap in small quantities from these guys (UK based) www.metals4u.co.uk/ so I have made up backing pads for the cleats and other high load deck hardware I've got already. (the aft cleats are what I'll use for series drogue attachment points so need to be quite butch..) Takes a little longer than just winding on some washers but i think worth it for high load stuff. I was thinking of either these (which seem to be pretty standard cockpit and deck lifeline attachment points on the yachts I've sailed on) www.s3i.co.uk/wichard-folding-pad-eye.php or these which are a bit more budget, and their watertight integrity is more concerning (having had these on a previous boat - the boots perish eventually). Half the price though, and somewhat directional in load - i.e. good for either end of a jackstay/jackline, but not so much for a single attachment point - jimmygreen.com/eye-bolts-and-u-bolts/78801-wichard-watertight-u-bolts#/283-size-8mm/872-length-80mm soooo, probably a combination of the two i think! |

Hey Pete, Thanks for the information. I dont have any experience with these at all so that is great to get your feedback. I saw the Wichard ones in the first link in your post and they seem quite robust and I like the fact that they lay flat when not in use. Cheers !Dan |

Hi Dan,
les 2 sont largement assez costauds.
Les Jimmygreen sont les cadènes de haubans sur de nombreux voilier de 7 a 8 mètres

... and probably a stainless pad as well, rather than just washers behind the nuts... Another option instead of a SS pad is to make up some 3-4mm think fibreglass plate from some of your left over fibreglass offcuts and resin. Way cheaper to build, shape and install. Make it on the bench on some plastic with peel ply either side. Make up as much as you want and cut it out with a jig saw or multi tool. You can glue it into place and even paint it! Cheers |

I agree with Greg & most, if not all of my backing pads will be epoxy /fibreglass. Also the Wichart fold down padeyes are very solid and the best part is they are not toe stubbers.

Thank you Greg,
I never thought of fibreglass backing plates, it makes perfect sense !

You put me thinking, so how about making up a chunk of plywood with 4mm of cloth epoxied on top. This could be cut and shaped to make backing plates of any size.

Solid fibreglass is all you need Jim. 4mm thick or there abouts

Not Toe Snubber  Knee snubber!!...not safe standing...and that is the biggest reason I am fitting SEADEK 5MM EVA foam all over the deck and cockpit and cabin sole .... |

Hey Pete, So, I ended up buying 4 of the folding padeyes ( cockpit and forward deck ) and 2 of the ubolt style for either side of the observation pod. Thanks for your input ! The backing pads will be determined soon. Others had mentioned using fiberglass for backing pads ..... I do like the idea of using fiberglass for the backing pads. I hadnt considered that because I'm not familiar with the actual strength of resin and fiberglass. Thanks ! Captdan |
