How a STEENSEN CUST ALUM BTS HIN breaks down
A current-format (1984–present) Hull Identification Number is 12 characters. Using the example SOH45678D424 (illustrative):
| Characters | Segment | In example | What it identifies |
|---|---|---|---|
| 1–3 | Manufacturer (MIC) | SOH | Identifies STEENSEN CUST ALUM BTS, assigned by the US Coast Guard. |
| 4–8 | Hull serial number | 45678 | STEENSEN CUST ALUM BTS's own production number for the specific hull (the letters I, O, Q are never used). |
| 9 | Certification month | D | Month built — A=January … L=December (D = April). |
| 10 | Certification year | 4 | Last digit of the certification year. |
| 11–12 | Model year | 24 | The boat’s model year. |

STEENSEN CUST ALUM BTS HIN FAQ
What does a STEENSEN CUST ALUM BTS HIN look like?
It starts with the three characters "SOH" — the Manufacturer Identification Code the US Coast Guard assigned to STEENSEN CUST ALUM BTS — followed by a 5-character hull serial and a 4-character date code, 12 characters total. STEENSEN CUST ALUM BTS built hulls across both HIN eras (1982–2001): boats before August 1984 carry legacy straight-year or model-year date codes; later hulls use the current month-letter format. The decoder handles all three.
Is STEENSEN CUST ALUM BTS still in business?
USCG records list STEENSEN CUST ALUM BTS as out of business since 2001. That's common for older hulls — the HIN still decodes normally, and the out-of-business date helps date the boat and guides parts-hunting toward salvage and owner groups rather than a dealer network.
How do I decode the year on a STEENSEN CUST ALUM BTS HIN?
On current-format HINs the last two characters are the model year and the 9th–10th encode the certification month and year. STEENSEN CUST ALUM BTS built hulls across both HIN eras (1982–2001): boats before August 1984 carry legacy straight-year or model-year date codes; later hulls use the current month-letter format. The decoder handles all three. Enter the full 12-character HIN above and the decoder works it out, including the legacy formats.
Where is the HIN on a STEENSEN CUST ALUM BTS boat?
On the outside upper-starboard (right) corner of the transom, within two inches of the top — required by 33 CFR 181.29. Since August 1984 an identical duplicate HIN is also molded into an unexposed interior location as an anti-theft measure. Both should match the title, registration, and insurance card exactly.
Is the "SOH" MIC the same as a STEENSEN CUST ALUM BTS serial number?
No. "SOH" is the Manufacturer Identification Code — characters 1–3 of the HIN — that identifies STEENSEN CUST ALUM BTS. The hull serial number is characters 4–8: STEENSEN CUST ALUM BTS's own production number for that specific boat (the letters I, O, and Q are never used). The full 12-character HIN combines the MIC, the serial, and the date code.
Can a STEENSEN CUST ALUM BTS HIN tell me the exact model?
Not on its own. A HIN encodes the builder, hull serial, certification month/year, and model year — not the model name or length. Match the decoded year and serial against STEENSEN CUST ALUM BTS records, the title, or a marine survey to confirm the exact model and configuration.
