 Post subject: 8:1 upgrade worth $500?

I have a bad shoulder that was caused, in part, by too much "pumping" the sails. I also find it hard to pull the main sheet in heavier wind.
After a lot of physio the shoulder is about 90%.
Should I go for the 8:1 blocks: I have the stock 7:1 now.
I have a quote of $500 for new harken H-2631 and H-2632 blocks. I also need 52 feet of sheet.
Anyone who has done this upgrade I would appreciate your advise.
Thanks,
Rob

There have been a few "stock" systems over the years. Do you currently have Harken or Seaway brand blocks? Do you have three individual blocks that hang from the boom bales or do you have one triple block that hangs from one bale? Also, what is the diameter of your mainsheet?

All of these factors help determine how good your current system is. If you've already got a decent 7:1 system, then you probably won't notice much going to 8:1. If you don't currently have a good 7:1 system, then an upgrade could make a big difference.

Rob, you have my sympathies.
I also have a 'weekend warrior' injury, (elbow) and I am fortunate to be married to a wonderful person who is also a great physical therapist.
The healing is going well, and we did okay at last night's 'round the buoys' racing...
however, I am wary about a recurrence.

SRM, we run with a Harken main-block, and three single blocks, with Robbline.
On Starboard, I am fine.
On Port tack, if there is traffic, life gets 'interesting'. If no traffic, I can use two hands.
One handed sheeting delays the full recovery.

Suggestions?
Will a bunch of cash ease the physicality that much?

(Our son says to buy a Tiger....more on that later).

Thanks for the answers guys.
I have the 3 Harkin (H001-H002-H001) on the bails with the Harkin H170/H048 block. I am currently using 10mm fusion mainsheet.

I'm not a big fan of the three single boom block arrangement. It doesn't tend to run very cleanly. There would probably be some advantage in just switching to a single triple top block and keeping your current bottom block.

Switching from 7:1 to 8:1 would theoretically result in about a 12% load reduction (in reality, it won't be that much since there are frictional losses with the added purchase), so not a huge difference. Whether it's worthwhile is really your call. Keep in mind that with the added purchase, you will also have to work more sheet- i.e. for a given puff, you will have to let out more line and pull in more line, so you won't be pulling as hard on the line, but you will be pulling more line.

Thanks, if I add a single triple upper, which bail is it best to mount to?

Center bale. The best way is to drill out the rivets on the bale and re-mount it so that it's aligned with the blocks when the boom is centered and sheeted in.
