1/2" three strand nylon is perfect for that boat...continous strand, hard lay gives highest ratings.

I wouldn''t use braided on anchors because you can''t see core damage if it happens...like from too much stretch.

See also Sampson''s not on "Strength" and "Working Load Limits".

Bigger is stronger, but also less elastic (under comparable loadings), which is an important characteristic in a rope (rope/chain) anchor rode. There’s no point in wildly exceeding the holding power of the anchor (or whatever the ‘weak link’ in the assembly is), at the expense of stretch.

Bigger is better but if you are going to be in the bay and inland the 1/2" will do the job. You might think about 5/8 that would be a little overkill but you would have an anchor line that would do the job no problem.

I’d look at the “Delta”, as an alternate to the “CQR” - cheaper, and some (including me) say better.

thank you Gord...just what I was looking for and exactly what I was going to get. 200 ft. of 1/2in 3 strand nylon , shackled to 20 ft. of 3/8in. chain.....and

you''re right, the anchor is probably the weakest link. I have a 15 lb. and 25 lb. dansforth.(and a small fisherman''s) I''m looking into getting a CQR at some point this year as well ( I sail on Hudson river/Long Island sound where I usually meet mud/sandy mud when anchoring)

A 28 Ft moderate displacement (7300#) boat is likely to require about 700 pound working load capacity, 1400 Lbs for a Storm Anchor, or 2100# for a Permanent Mooring.

Various Working Load Limits in Pounds:
½" Three-Strand Nylon Rope = 709# WLL (Stretches to 150%, Good Shock Absorption)
½" Double-Braid = 816 # (Stretches to 130%, Fair Shock absorption)
3/4" Three-Strand = 1598#
3/4" Double-Braid = 1813#
1/4" Hi-Test Chain = 2600#WLL
5/16" Proof Coil Galv. Chain = 1900#
3/8" Proof Coil Galv. Chain = 2650#

Unless it’s very large (you didn’t specify), your Danforth anchor is very likely to be the limiting factor (weak link).

I’d probably use ½" (or 5/8" @ 1114# WLL) Three-Strand Nylon.

FWIW,
Gord
