Why RegKnot
The regs are complex.
Getting cited shouldn't be.
Commercial mariners navigate an overlapping web of regs — the IMO conventions (SOLAS, MARPOL, IMDG, COLREGs, STCW, ISM, plus the IGC, IBC, HSC and Load Lines codes), the U.S. CFR Titles 33/46/49 and USCG guidance, and a growing set of flag-state regulators (UK MCA, AMSA Australia, Singapore MPA, Hong Kong, Norway NMA, Liberia, Marshall Islands, Bahamas). Thousands of sections that cross-reference each other, change without warning, and vary by vessel type, tonnage, flag, route, and cargo. One missed detail during an inspection means deficiency citations, vessel detention, or costly litigation.
RegKnot was built by an Unlimited Licensed Captain and her engineer brother. We know these regulations because we live them. This is the tool we wished existed.
General-purpose AI doesn't have access to the SOLAS Consolidated Edition, the STCW Convention, or the ISM Code — and it can't tell the difference between what applies to your towing vessel versus a containership. RegKnot is built on the purchased source texts and your vessel profile, so every answer is specific to your ship and cites the exact section you can verify.
How we're different
Why not just use ChatGPT?
Honest answer: for casual maritime questions, you can. For compliance answers that need to hold up to a Coast Guard inspector or a port-state control deficiency report, here's what general-purpose AI doesn't do.
Every section we cite is verified against the actual text
ChatGPT and Gemini will cheerfully invent a CFR section that doesn't exist. RegKnot runs every citation through a verification pass before you see it. If we can't ground a claim in the retrieved regulation text, we hedge instead of guessing — and we tell you exactly what we couldn't verify.
IMDG Code 2024, SOLAS Consolidated, STCW with current supplements
IMO conventions are paywalled. General AI was trained on web summaries and outdated copies. We've ingested the licensed editions — the IMDG Dangerous Goods List, the full SOLAS chapters, STCW with the latest MSC resolutions, the ISM Code, plus 9 flag-state regulators. When you ask about UN 3480 stowage, we have the actual row from Chapter 3.2.
The answer changes based on your ship
Subchapter L OSV vs Subchapter K small passenger vessel vs U.K.-flag bulker in U.S. waters — the regulatory answer is different for each. RegKnot reads your vessel profile (flag, tonnage, route, subchapter, cargo) and scopes retrieval + answer accordingly. Generic LLMs give you the same one-size-fits-all response no matter what you operate.
A Master Unlimited captain runs the audits
Karynn holds an Unlimited Master license and reviews actual user answers every few days, flagging anything off. When she finds a gap — a missed Annex V exemption, a wrong jurisdictional cite — the prompt rules and ingest pipeline get fixed within the week. This isn't a wrapper around an API. It's a regulatory tool with a mariner in the loop.

Lifeboat Inspection Requirements
46 CFR 199.190 your vessel must conduct inspections on the following schedule:
Weekly:
Visual inspection of survival craft, rescue boats, and launching appliances for readiness.
Monthly:

Annually:
Full operational tests including launching appliances at loads from light to full load 46 CFR 133.45(b).
Note: SOLAS Chapter III applies to vessels on international routes in addition to these CFR requirements.
