Attachment for storm sail on madt

Hi, I'm installing a baby stay for stormjib on a 34 footer. I have fixed the attachment on deck, however, since the boat is in the water i need to climb up the mast and drill a Big hole for normal mast bracket. Are there any brackets which Can be attached by rivets? Furthermore, Can I use dynama or similar instead off wire for the stay?

People are using Dyneema for standing rigging.

I would not use pop rivets to attach a tang for a stay to hold a storm jib.

Here's the thought I have about Dyneema (and I plan on doing what you're doing): while Dyneema has great tensile strength, it is vulnerable to friction. you can rub it across a metal edge and cut it. I think it would be significantly weakened by the hanks. I'm going to use wire.

Wire would be a better choice for the forestay because of wear by sail hanks. Synthetics would be more acceptable for the running backs that you should also be installing. Keep in mind that the synthetic probably will have about 1/3 life of a wire running back.

See the following link for a discussion of rigging inspection and expected lifetimes: http://www.navtec.net/assets/img/dat...ng-Service.pdf
