Probably sufficient, but more chain would be better -- gives you more weight on the bottom and improves holding power. Also, my experience with plows is the heavier the better -- 25lb is near the low end of useful weight for a plow (IMHO).
I have not done much sailing on LIS (some, but not much), but in general the NE coast is pretty rocky. A plow is a good choice for rocky bottoms. Someone with more detailed local knowledge of your route
can advice better than I. Have you chosen specific places you want to anchor? Nautical charts
will often have abbreviations which indicate bottom types in specific areas on the chart so take a look at charts
for your intended route
(good idea to do anyway). For anchoring
, you are mostly interested in good protection from wind
and waves, good holding (type of bottom), and reasonable anchoring
depth. In your area be sure an check the tides too because big tidal height variance needs to be accounted for when you anchor.
The ratings for length of boat are a bit bogus -- I think done to make purchasing
simpler for retail customers with limited experience -- boat length (LOA) is largely irrelevant -- what really maters is weight and windage -- I think retailers just dumb this down to LOA
(don't know how much actually analysis they put into these recommendations). I'm skeptical of these charts too, so I usually suggest that people use these charts to initially select an anchor and then go the next largest size.
All chain, appropriately sized chain, is good (except for all the added weight in your bow) and is more convenient when working with a windlass
. Do you have a windlass
? Many cruisers run all chain rodes because of the increased holding power, chafe resistance, and more convenient windlass use.
On my boat, a catamaran
, I run what is called a "combination rode" (which is what you currently have) -- meaning some rope and some chain. In my case. I run over 60' of over sized chain backed up by about 200' of 3-strand nylon. Reduces weight forward (versus all chain) and gives me most of the advantages of all chain (esp given that I usually anchor in shallow water).
