How to conduct a boat manufacturer database search lookup. Domestic boat manufacturers are required by federal law to obtain a unique Manufacturer's Identification Code (MIC). The same applies to domestic importers of foreign built vessels. This code must be incorporated as the first three characters of all hull identification numbers assigned. Each boat has a unique HIN that you can use to identify it. The HIN number in most cases is a 12-character serial number that you can use to uniquely identify the boat. They can be compared to the VIN found in automobiles. However, the HIN number is only.

Since November 1, 1972, federal law requires all boats, including inflatables like rafts, IKs and SUP boards, manufactured in, or imported into, the US to have a unique 12-character identifier called the Hull Identification Number (HIN). This is often referred to as the “boat serial number” or “boat ID number”. The number is usually found in the stern and can be engraved on a plate or stamped into the boat material.

For boats built or imported after August 1, 1984

The system for building the HIN changed after this date. Since most of you will be checking on boats after this date, we’ll cover this first.

Example: ABC12345J314

Manufacturer ID Code (MIC)	Hull Serial Number	Date of Manufacture	Model Year
ABC	12345	J3	14

Manufacturer Identification Code (MIC)
Entering the MIC into this US Coast Guard database will get you the manufacturer and their location.

Hull Serial Number
These five characters are assigned by the manufacturer. Apocalypto full movie in hindi online watch. They are normally numbers, but letters (except I, O and Q) may also be used.

Date of Manufacture
The letter is for the month of manufacture:

A = January
B = February
C = March
D = April
E = May
F = June
G = July
H = August
I = September
J = October
K = November
L = December

The number is the last digit of the year of manufacture. Since there’s only one digit, it must be interpreted by the Model Year. In our example, J3 designates that the boat was built in October 2013.

Model Year
In our example, the year is 2014.

Note: Open pcb file in altium. Cataraft tubes are not considered to be a boat, until they are married with a frame. An abbreviated HIN of 4-5 numbers, followed by a letter denoting month of manufacture, and three numbers representing the year of manufacture and model year, as described above, may be attached to the tubes. Example: 1234(5)E516, would have been made in May 2015.

For boats built between November 1, 1972 and July 31, 1984

Note: This was the first attempt to create the HIN… and parts of it are a bit confusing.

Manufacturer Identification Code (MIC) and Hull Serial Number are the same as described above.

Date of Manufacture
Here’s where it gets confusing. Manufacturers were given the option of giving either the date of manufacture, or the model year.

HIN with Date of Manufacture
Example: ABC123451076 (October 1976) The 9th and 10th characters are the month, and the 11th and 12th characters are the last digits of the year.

HIN with Model Year
Example: ABC12345M72D (November 1972) The 9th character “M” stands for model year. The 10th and 11th are the last two digits of the model year. The 12th is the letter designating the month of manufacture.

Now, here’s where the government got cute:

A = August
B = September
C = October
D = November
E = December
F = January
G = February
H = March
I = April
J = May
K = June
L = July

A Grumman Sportboat, (also Sport Boat, SportCanoe, or Sportee) is a 15' 4' long, 43' wide square stern canoe manufactured in America.^[1] It, as well as the Coleman Scanoe, are patterned after 'Grand Lakers,' wooden fishing guide boats built on Grand Lake, Maine for oar power, subsequently modified for the advent of small outboard engines with the addition of more bearing aft and a flat tumblehome transom.

The Sport Boat is designed to be rowed, sailed, or powered by an outboard motor, and is among few designs to be fairly efficient at all three. It can also be poled or paddled, but is too wide for efficient paddling. It is manufactured in a fashion similar to an aircraft, made of a stressed skin aluminum, riveted together, and weighs slightly over 110 pounds. In current production, it is rated for 805 pounds capacity and a 7 horsepower (5.2 kW) outboard motor. It can plane with as little as a 3.5 hp motor, and has been used with as much as a 25 hp motor. Moving a lone operator forward to the middle seat enables planing performance over 10 mph with as little as 2.5 hp. Ballasting the bow greatly improves operation under power.

As a canoe, the Grumman Sport Boat was originally rated for an 1,100 pound payload. Due to its unusual planing ability, the United States Coast Guard in the 1970s applied a different rating rule. Without any changes to the boat, the payload rating dropped to 550 pounds. Evolving rules for planing boats, requiring level flotation when swamped with maximum payload and rated engine, led to the demise of production by Grumman in 1979. The inaugural issue of Small Boat Journal decried the end of Grumman's Sport Boat production in a black-bordered article evocative of a eulogy. The Grumman Sport Boat was named by the editors of Small Boat Journal as one of the 10 best small boats of all time.

Boatbuilder and designer Robb White wrote of one in his essay 'The Chicken Feed Boat,' and made a strip-planked wood variant and sold the plans. Small Boat Journal founding editor David Getchell wrote a feature SBJ article about the SportBoat and bought one, and mentioned it again in 'Outboard Boater's Handbook: Advanced Seamanship and Practical Skills.'

Early models included the mast base clip and gunwale holes to use with the Grumman factory sail kit, with either a gunter or lateen rig. Sail kits are long out of production.

1986 also saw the Grumman Boats’ purchase of an assembly plant in Minong, WI. All units produced at this location were assembled with parts supplied in the flat, shipped from either Marathon, NY or Arkadelphia, AR. This was done to achieve lower freight costs to dealers and consequently better sales penetration in the North Central and Northwestern market areas of the country. This strategy had been employed to a lesser degree some years earlier with limited success at Grumman sister locations in Carmichaels, PA and Corcoran, CA.

SportBoats remain popular in the Great Lakes and midwest, and are a favorite of duck hunters, frequently camouflaged with the oarlock sockets removed to eliminate hang-ups in grass. Except on Alaskan rivers, Sport Boats are uncommon west of the Rockies. The University of Washington Aquatic Recreation Center has a dozen or so heavily used and extensively repaired SportBoats in its rowing fleet on Lake Washington at the Montlake Cut.

The Marathon Boat Group, a company of former Grumman managers and investors, reintroduced production of the Sport Boat with sheathed flotation under the gunwales to comply with the level-flotation rule. Originally, the Sport Boat featured twin sets of oarlock sockets, but the current version has only one, and the sheathed flotation makes retrofitting the second set difficult. Marathon continues to make the Sport Boat and other Grumman canoes, and in 2000 acquired rights to use the Grumman name and logo. (see also 'Discussion' in this category). L. Manser, England.
