Due to aggravating my hital hernia few weeks ago while sailing in heavy winds, I have decided to upgrade to 10:1 ratio main sheet blocks. I found set of 57mm Carbos on Murrays site but price is as steep as the ratio. Do any of you has a set in good shape and is wheeling to sell it or can you direct me where can I find it for decent price?
Should I be concerned about using that high ratio blocks on boomless Nacra 5.0 rig?

I have some for sale, but I am not sure that they will give you the desired results. When you get that much purchase, it leads to much more sheeting in general. You will nearly require 2 hands to sheet after tacks which doesn't leave many left for steering.

I upgraded my Viper mainsheet from 9:1 to 10:1 and didn't notice a huge difference plus there's now more sheet on the tramp. Looking back I would have stayed with what I had. 10:1 sounds like an awful lot for a 5.0, the one I had used a 7:1 I believe, don't remember what my N500 had

yes - Dont get me wrong ... this is do-able, but if you get excited and over sheet... you are risking your rig.

I upgraded my 8:1's to reduce stress on my blown out shoulders by adding a dynema line through the top block and hanging a 40mm off of it. - worked fine - cost ($20?)

i have a hiatal hernia, but what i think you mean is an 'inguinal hernia', of which i also suffer with from time to time. i have no opinion as to whether 10:1 blocks with help with either condition.........

Hiatal hernia is a condition in which part of the stomach sticks upward into the chest, through an opening in the diaphragm. The diaphragm is the sheet of muscle that separates the chest from the abdomen. It is used in breathing.

@ cbacho "You will nearly require 2 hands to sheet after tacks" I'm new and learning but why would it take 2 hands to tack?

Hand over hand sheeting in all the extra line

It is for sure hiatal hernia.

I think I will wait a little with block changing to see what develops.

I am still using the original Nacra 7/16" main sheet that is very soft and I think a little strechy, it tungles a lot. Do you think changing main sheet will help? What would you recommend?
