When I started cruising in the early 90s, the commonly recommended battery configuration was to have equal size batteries and designate the banks 1 and 2. You either started the engine and charged batteries using ALL, then switched to 1 or 2 after the engine was turned off, or you used 1 exclusi

I found my reference and provided a link. It also shows the "better way" for a 1-ALL-2 arrangement. I guess the risk of switching the batteries is the possibility of overshooting to OFF or simply turning the wrong way to OFF. As I recall Edd just recently had a problem where his switch terminals

You really need to do all the math, not just look at the elongation spec. 9mm Crystalyne (3/8 diameter is about the smallest practical for a winch or your hand) has an average break strength of 11500 pounds. So you need 3300 pounds of tension to get 7" of stretch. The average man can generate

Rick, I think you made a typo, decimal in the wrong place, at least according to their formula. Should be 3.4% (3.42144) for 1/8 inch 7 X 19 type 302/304, according to my calculation using their formula for estimation. I checked because I found it difficult to imagine any wire survivi

It is not beyond belief that I screwed up, though I did do the calculation twice. I agree that the break strength of 1/8" wire is about 2000 pounds. 34% stretch seemed high but was not unreasonable for the permanent deformation of the wire that would have happened before it broke. 3.4% is unreas

Hi David, As another data point / alternative: All my halyards have been replaced with New England Ropes Sta-Set at some point. I just replaced a couple spin halyards and used Sta-Set again as per my riggers' recommendation. According to my rigger the sheaves on our boats are 'Hybrid sheaves"

Stay-set is fine for me except for halyards. Particularly headsail and main. I do have stay-set for my spin halyard. It is increadible to feel the two side by side. The stay-set is SSOOO stretchy compared to the crystalline. The sheaves are a v-groove and designed for either. I was warned tha

Stay-set X is a reasonably good alternative. It also comes down to price. There is no one particular rope that always has a better cost/stretch value. Availability and turn around time play into it as well. Josh On Sep 29, 2014 5:16 PM, "Michael Clow via CnC-List" wrote: > I use Sta-Set X on j

Thanks Rick, I knew what I liked and why I just didn't have time to find the resource. Sampson warpspeed is a close competitor so which ever is cheaper per foot or meets my color desires is what I use. I particularly like that those high tech lines float. Josh You really need to do all the math,
