^^^ Soft shackles are sometimes set-up with a bit of string to help with opening the loop.

^^  The length of the bury is much shorter as the force trying to make it slip is so much less because of the knot.  For example, the recommended length of a splice is around 60 diameters although 28 might be enough.  With these hybrids, around 10 diameters seems safe with 6 perhaps the lower limit.

I was thinking that the length of the sting used for the knot plus the bury must be approaching the amount of line used in a splice.

 

So, hybrid v splice:

 

Advantages:

 

In halyard use the knot replaces a ball if you need one.

 

Tucking the tail likely makes the knot less likely to catch.

 

The standing part is 1d.

 

Costs:

 

Involves both a knot and a splice.

 

May be hard to set properly with hand strength.

 

Takes the space of a halyard ball when you don't need one (ie. when hoisting closer to the sheave is desired).

^^^ Is the motivation to avoid a splice just to keep the diameter over the sheave down? Seems that these tucked constructions use about the same amount of string and sweat as a splice.

^^^ FWIW, 1/4 amteel splices with 3/8 tenex like that. I think I will keep a long tail of amsteel  in the splice so that the doubled line goes through the rope clutch at all the reef positions. "The Plan" is a brummell splice and ess stitching.


In Topic: What size Racor

11 April 2014 - 02:10 AM

My little Racor 110A is all-metal so you can put it in the engine compartment, is easy to change, the filters are half the price, and it's rated at 35 GPM, which is more than adequate for my 3GM30F (27 hp). For some reason, Racor doesn't push this one as much as the other designs.

I have a friend who replaced his 3 banger Yanmar on the engine filter with one of those and he loves it.
