Marine Sanitation Device
MSD Inspections Now Required
Alabama Water Safety now requires that all vessels with
Marine Sanitation Devices (MSD) on board (otherwise known as a head with a
holding tank) be inspected yearly and display a sticker acquired from the
The inspection/sticker usually costs anywhere from $20 to $50. For more

What they do
Dock lines secure your boat to a dock, or to another boat when
rafting, either temporarily or semi-permanently. These applications
demand different types of dock lines.
How they work
When your boat is away from its regular slip or mooring, you need to
have some designated nylon lines aboard, preferably with spliced
eyes, ready for use when you tie up somewhere. We call these
lines. The eye in the end is easily
passed around a cleat or piling by someone on the dock and the
bitter end is adjusted on board. There are dozens of combinations
of diameters and lengths.
lines are also made of nylon, but
differ from transient dock lines in several ways. First, they must
be protected from chafe, the enemy of all lines in constant use.
This calls for leather, rubber or fabric chafe gear where the line
passes through the chocks, and possibly a chafe sleeve on the eye
where it goes around the cleat on deck. At the dock, lines should
be protected from chafe using eye splices and shackles if the dock
has rings, or eye splices and short lengths of chain if the dock has
cleats. Permanent dock lines should be cut to fit the particular
boat in the slip.
What to look for
Dock lines should be made from nylon, which has a superior
combination of strength and stretch. Both three-strand and braided
construction are common. Three-strand stretches more, is very
abrasion- and snag-resistant and less expensive. Braided nylon is
stronger, comes in colors, and has a nice feel or “hand”.
We recommend 1/8" of line diameter for every 9' of boat length.
Larger lines will wear longer but stretch less. See the chart

used on the bow and stern. Spring lines should be equal to your
