Shroud length and mainsheet blocks

I spoke to Stan at Murrays and he was indeed very helpful. My forestay seems to have already been updated at 17'6". Stan recommended rigging the boat, but since it is snowing here, and the old shrouds were kinked, I am going to order the 19'-3/4" shrouds and rig it up when it gets warm.

My hope is that this will allow me use use the stacked mainsheet blocks that I already have. If I decide to upgrade to low profile blocks, I can also swap to shorter shrouds. I guess the current length is 18'11".

I don't think that the boat was sailed for years, so I am not putting much faith in where the pins were.

Thanks,

Phil
