I have a spare mainsail halyard
which comes out of the aft part of the masthead truck over a block. I am planning to use this halyard
for two purposes:
1. To hoist a length of stainless lifeline wire to use as a HF/SSB antenna
2. To take some load off my davits
, one of which cracked last year.
And I want to do both at the same time.
Here's what I have in mind:
I will have a length of stainless lifeline or rigging
wire made up with swaged loops at both ends. The top look I will simply shackle to the halyard.
I will have four more pieces of rigging
wire made up which I can shackle to the four lifting points in my dinghy
, making a kind of cradle
. Say 150cm each, terminating in a ring or a big shackle. If I lift
on this with my halyard, I will take load off the davits
and at the same time, I gain a safety
-- redundant lifting system, in case something happens to a davit or davit fall or davit motor
Here's the rub -- I can't quite conceive the best way to attach the lifting cradle
to the antenna
wire which will insulate the lifting cradle from the antenna. I guess I could have a short piece of Dyneema
made up with shackles spliced in both ends, but that will be fairly expensive. I guess I could just tie the piece of Dyneema
, but that's slippery stuff -- what would be the right knot
? Or would it be better to tie a loop, and loop it through the lifting cradle and shackle the other end to the antenna? Or maybe tie a loop, cow hitch it to the lifting cradle, and shackle the other end to the antenna?
Any tips? I think my knot
expertise is overtaxed here.
