Block size main sheet 39' cruiser

Greetings. I just finished moving main sheet traveller system from cockpit to top of cabin in front of hatch on Corbin 39 (23,000 lbs) and I am now trying to devise a mainsheet system to fit. I have three boom bales for blocks and a new traveller car. The configuration of the dog house on these boats makes it very difficult to run a line back from the base of the mast to the cabin trunk, and thus I am thinking of using a triple fixed block with a cam and becket on the car, run through the three blocks. My question is whether or not a system like this would be strong and safe enough, as well as what size blocks I should be using. Any advice would be appreciated.

I would recommend this one (picture) and using blocks for, at least 7/16" line.

Head to and take a look at the ways they have online of running a mainsheet. I can't really visualize what you are trying to do, but if harken doesn't have it up as an example, I wouldn't recommend it without visually inspecting the boat.
