Bob, use as much dyneema as possible. Its a good thing, and its light.
All my back stay is Dyneema, from the mast top to the bottom, and I am very happy, its light and almost strech free.
Now for the arrangment, I dont think thiose tiny little things from Ronstan
would do. Besides, I would not use ronstan
for that...I don't like them that much, they are ok for non critical stuff.
I think the load on that boat with thoise areas is around 1000 to 2000 lbs force. For real!!!!
For the blocks this is what I think:
For the main single block, and for those sail areas, I would use a Lewmar
60mm block or a harken
57mm. With a SWL of at least 2500lbs. With a breaking load of at least double that.
For the purchase, I would use a triple block or a beefier double with a SWl of at least 2000 lbs. A Lewmar
60mm or a Harken
57mm would do.
However for the cleat
I would use a triple with becket and cleat
, also with a SWL of at least 2000lb, instead of cleating the line
on the boat structure. Several reasons:
easier to release
easier to cleat
Give me some time I will tell you some references. By the way, prepare at leat $400 to do it.
