Spinnaker blocks

Re: Spinnaker blocks
We use Harken 76mm singles back at the handrail bases and 76mm ratchets on the rails opposite of the primary winches.
Re: Spinnaker blocks
Tim,
thanks for the reply.
I see in West Marine 2010 catalog they list a Harken Carbo Air Block at 75mm sheeve diameter, is that the single unit for the low handrail attachment point? not seeing the 76-mm units.
Also, I have never used a rachet block for the forward spin block previously.
it that a critical feature in your opinon?
looks like the 75mm Harken Carbo Ratchet or the 75mm Harken Carbo "Ratchamatic"?
any info you have on design Max. Working Load (MWL) for these blocks, as the range on some of the Harken blocks I mention above show differences in the MWL from 750 to over 1200 lbs. I am thinking the loads should match?
lastly, I am replacing a couple of other blocks and could use some advice here too.
- control bullet blocks at the ends of the main traveler?
- and mostly halyard blocks at the base of the mast?
