Stuart from Vermont writes in and asks:

I would like to use a shockle from my bow eye (i.e., the one that the trailer web hooks up to) rather than my bow cleats for achoring, so as to avoid chafe on my rub rail. It is a 23′ Precision, which is a shoal draft monohull sloop. I think a 24 inch is better so that I can leave it hooked on the bow eye all the time and just clip it on to my 1/4″ proof chain rhode. F2 or F3? And the caribiners will fit through the 1/4 inch proof chain per your website, correct? And note that this is for setting a lunch hook, not for overnight or mooring purposes. Please advise. Thanks very much.

I would suggest a 24″ F3 for your use.  While an F2 would certainly work fine as well, the added resistance of the F3 will ensure that you don’t get a real wallop on your chain when the 2′ wave from the wake of that 30′ powerboat hits you. Our carabiner will indeed fit 1/4″ proof chain
