Although most people seem to be in agreement what spares they would bring where the engine is concerned. You don´t read so much about what "spares" to take in regards to the rig, mast and boom. If the mast comes off, that is a different cup of tea altogether. But I am more referring to issues that can happen underway.
I read a lot of cruising books and follow many cruisers and fraying 1x19 stays are pretty common or a boom breaking in half or the goose-neck breaking (not the strongest point on most Jeanneau´s). If this happens mid-ocean.....what do you do.
I already have a complete gooseneck set on board, including the mast bracket. In regards to the boom breaking, I am considering taking two 80cm long alu plates, pre-drilled with holes, which can me pop rivetted onto the boom.
I am thinking towards stretch free dyneema as spare rigging, instead of 1x19 stainless wire. It can be tied up or wrapped around something easily (i.e. the mast head) and fed down along the spreaders. If you get the 0% stretch dyneema, you can even use a normal turnbuckle to tension the dyneema stay. This should be seen as an emergency solution.
Anyway, anybody any thoughts or comments or tips or own experiences?

If you are solo, how are you going to get to the masthead and even if you are prepared for that, do you really want to climb up there if you have a broken stay? I had thought that it could be handy to have an extra genoa & main halyard in case the stays break and the mast need support. It has just occurred to me that if I lose the mast, as it's deck stepped I'm perhaps likely to lose the whole mast which includes the spinnaker pole which means I lose any jury rig option I wonder if 2 alu plates would be the right way to go? I suppose if they are curved to the boom's profile, then fine, otherwise maybe you need more than 2. I guess large curved would be stronger. Probably something you could get z-spars to make by cutting up a section of a Z480 boom. Do you have the large sized pop rivet gun? I keep meaning to buy one as I only have a small one. The SS rivets are d**n expensive

Currently I have footsteps up to the first spreader, but will continue to the top when the mast comes off for final preps. I also have a self climber unit, which works ok in a marina, but not really at sea. The steps are excellent, also at sea (I do wear a safety harnas when I go up).
Yes, I would have these plates not curved, but angled so that the sides touch the top and bottom sides of the boom. That is easily done and makes the plates more rigid.
As I am in the boatie business, I have 3 different rivet guns. The small one, a large one, which is not easy to use when suspended in a mast as you really need two hands to work that thing), but the best is the big harmonica unit. This thing is excellent and can be used with one hand and whacks any size rivet into anything. I mainly use monel rivets, as they do not cause corrosion issues with either alu or stainless. But, I always use some tefgel anyway (tefgel is normally used where stainless and alu touch). Tefgel is also used for any ss bolts or screws into aluminium, so the two materials do not react and corrode and or ceize.

I carry a lot of single-braid Dyneema SK75 as spare line which can be used for rigging repair. It is light, easily stowed and is easily worked with almost no tools (a knife and a screwdriver will suffice in a pinch). A simple modified Brummel splice will put an eye at one end of the line in a matter of minutes. Tension is also quickly applied by using time-honoured lashings.

"Harmonica" riveter is new for me, On y va. Can you give a pointer to descriptive literature?

I want to get one as I need a rivet gun that can handle the larger sizes. They seem to either cost an arm and a leg or are so dirt cheap on ebay that I worry they would not survive more than a couple of rivets

Ah! Compound force in a limited space. Nice! Thanks!

I happened to drop in a store that was selling one of these today. They were asking $230 for it I think I might order one of ebay for 1/10th of the price and hope it lasts
