ROPE AND CHAIN
CHAINWHEEL SELECTION GUIDE
In order for your windlass to retrieve and deploy the anchor and chain
smoothly, without jamming, it is vitally important that the chain and
chainwheel (gypsy) match.
Unfortunately all chains (whether metric or imperial) are not necessarily
manufactured to the same tolerances for a given chain size. Therefore,
Maxwell has devised a global chain and chainwheel spreadsheet which will
help you to figure out what chainwheel you need to order, for the chain you
are using, to fit and work correctly with your Maxwell windlass.
If you know the chain size and manufacturer, then simply go to the Maxwell
web site, look up your chain, scroll down to your windlass and a dot in the
matrix will indicate and guide you to the chainwheel to be used with your
specific windlass and chain. If you do not know the chain size and
manufacturer, then use the illustrated chain diagram (below) and indicated
dimensions information to ‘measure’ your chain. Send this information to
your Maxwell dealer, who will then help you figure out what chain you are
using and therefore what chainwheel must be used with your Maxwell windlass.

CHAIN INFORMATION
There are various Grades of short link chain. The Grade relates to the raw
metal quality, strength and finishing process. Both galvanised and stainless
steel chains are available.
Chain Specification is the Standard a chain must be manufactured to in order
to comply with a given International Standard.
Outside of North America the most common types of metric short link chain
are DIN766 and EN-818. Within North America the most common imperial chains
are BBB and G40.
The important thing to keep in mind is to select a chain grade and
specification that complies with recognised standards.
In addition to the chains listed above, Maxwell can supply a variety of
alternatives to meet any market demand. Contact your nearest Maxwell Dealer.
ROPE AND CHAIN
Maxwell can supply a full range of anchor rodes including chain only,
rope only or pre-spliced combination rope and chain rodes. Chain, suitable
for vessels up to 100 metres (about 300 feet), is available in short or stud
link variations in both metric and imperial sizes. Maxwell stocks both
3-strand and 8 plait (braid) nylon rope commonly used on vessels up to 20
metres (65 feet) as well as ropes and hawsers commonly seen on superyachts.
