Here we go again on the All Chain Topic!
From piecing together various bits and pieces of information over the years, it would appear that Cutter Marine back on the East Coast has been setting up C-Dorys for some time with this preferred set up :
1. 100-150 feet of chain, 1/4" GS-4 High Test
2. Simpson Lawrence Sprint 600 vertical windlass
3. S/L Delta Fastset 14 lb anchor
4. S/L Pivoting Anchor Roller
5. suitable anchor swivel
6. not sure about the locker drain, but probably installed
(all of this subject to buyers's approval and modified by individual preferences, of course)
We've heard (and surmise) they do this for the following reasons:
The extra weight of chain (75- 112 lbs vs 25 or so for a conventional rope and short chain rode) helps do the following:
A. Balances the extra weight of modern four stroke engines (C-Dory 22 was designed for 2 strokes).
B. Drives the boat better through the short steep chop experienced on East Coast Bays (vs large swells on open oceans) This is done as an alternative to installing trim tabs.
C. Enables boat to use much shorter scope in crowded anchorages.
D. Keeps people guessing about this set up and gives us something to go over every so often.
From our previous discussions, it also becomes evident that:
1. Folks don't much care for the big chain approach who are more concerned with keeping the bow as light as possible so that it rides up easier in steep swells.
2. Neither to those who have to anchor in real deep situations where they need 300 -600 feet of rode. They obviously find the first 100-150 feet of chain to be both more chain than they need and too much extra weight and bulk to carry around.
So the all chain may not be for you.
Several of us do use it, however, finding that:
1. It does indeed hold the bow down in the chop and works like trim tabs in that respect. No adverse affect on boat balance noticeable.
2. We do indeed have to let out a lot less rode when anchoring.
3. The heavy chain helps quiet the boat's ride at anchor, and also helps minimize "searching" in wind shifts.
4. It definitely does not slip in a windlass, unlike some ropes.
5. Chain wears a lot less than rope, and doesn't have to be replaced, period.
There are undoubtably more pros and cons of this and other set ups, but I think you can see the major ones here. The choice depends on where and how you anchor and your individual preferences.
While I have 100' of chain followed by 150 feet of 1/2" rope as a primary set up, I also have a traditional 15" chain and 200' rope one for use where preferable.
The 100 feet of chain weighs 75 lbs, plus the anchor, the 150ft = 112lbs+anchor.
Have you ever tried to lift such a "animal"? Feels like you've got a Dead Lead Alligator by the tail!!! I can hardly move the 90 lbs or so of my set up by hand. I wouldn't have an all chain rode w/o a windlass. Good luck, whatever you choose! Joe.
