Hull Numbers (HIN)
HIN
All boats manufactured or imported on or after November 1, 1972 must
bear a HIN. The HIN is a 12 character serial number that uniquely
identifies your boat. The HIN has an important safety purpose. It
enables manufacturers to clearly identify for boat owners the boats that
are involved in a defect notification and recall campaign. A HIN is not
the same as a State registration number, which may be required to be
displayed on the bow of your boat. The HIN is a Federal requirement;
your boat’s registration number is a State requirement similar to the
license plate on your car. The HIN, however, is required to be shown on
the State certificate of registration.

**Key to Month of Model Year*
*Figure 1 - HIN Formats Before August 1, 1984*
The boat manufacturer must display two identical hull identification
numbers, no less than one-fourth of an inch high, on each boat hull. The
primary HIN must be permanently affixed (so that it can be seen from
outside the boat) to the starboard side of the transom within two inches
of the top of the transom, gunwale, or hull/deck joint, whichever is
lowest. On boats without transoms or on boats on which it would be
impractical to the transom, the HIN must be affixed to the starboard
outboard side of the hull, aft within one foot of the stern and within
two inches of the top of hull side, gunwale, or hull/deck joint,
whichever is lowest. The starboard outboard side of the hull aft is the
preferred HIN location for many manufacturers. On catamarans and pontoon
boats the HIN must be affixed on the aft crossbeam within one foot of
the starboard hull attachment.

*Figure 2 - HIN Format After August 1, 1984*
Boats manufactured or imported on or after August 1, 1984, also have a
duplicate secondary HIN affixed somewhere on an unexposed location
inside the boat or beneath a fitting or item of hardware. The purpose is
to help authorities identify your boat if a thief or vandals remove or
damage the primary HIN on the transom. It is illegal for anyone
(manufacturer, dealer, distributor, or owner) to alter or remove a HIN
without the express written authorization of the Commandant, U.S. Coast
Guard.
The regulations prescribe the format of the HIN. The first three
characters are a MIC (Manufacturer Identification Code) assigned by the
Coast Guard to the manufacturer or the person importing the boat;
characters four through eight are a serial number assigned by the
manufacturer; the last four characters indicate the month and year the
boat was built, and the model year. Prior to August 1, 1984, the
manufacturer had the option of expressing this in the form of a model
year designation.
The Coast Guard maintains a searchable database of MICs if you want to

Hi all,
Recently purchased a 1979 C&C 30 MK1, I have sent a payment to get the
owners manual but I am unsure if it has rigging information.
So I am wondering if anyone would be willing to share some images of
how their Cunningham/Downhaul may be rigged...
Additionally, for some reason the waste tank behind the bulkhead in
the head has been abandoned, does anyone have any information on how
this was setup?
I am really liking this boat (I have owned many), she is in very good
condition and just needs some TLC, oh I am also interested in adding a
bow anchor roller, has anyone done this to their 30Mk1?
Does anyone know how many blocks should be used as mast spacers and
their placement? mine only has 5 and are installed randomly...
Lastly, how do I know the hull # for placing on my new Mainsail?
Thank in advance for any help, pictures and advice...
