The Problem

Excel wasn't built for federal compliance documents.

Missed Entries

The weekly lifeboat inspection that didn't get logged. The stability verification referencing the wrong CFR section. The fuel changeover missing flash point data. No system is checking whether you hit every requirement.

Inconsistency Across Your Fleet

Every master formats entries differently, abbreviates differently, groups drills differently. When OCMI or PSC reviews your logbooks, the inconsistency creates questions — and questions create delays.

Zero Shore-Side Visibility

You don't see what's in the logbook until the book arrives at the office after the voyage is over. By then, the gaps are permanent. In a casualty investigation, those gaps become evidence.

Adapts to your vessel's subchapter automatically.

Select your vessel class once in Ship's Particulars. The entire system reconfigures — navigation, required entries, CFR citations, compliance tracking, and PDF output all update to reflect the correct regulatory requirements for your vessel type.

Subchapter-Aware Compliance Dashboard

Set your vessel class once — the entire system reconfigures. Weekly, monthly, quarterly, and annual requirements tracked with real-time status: Current, Due Soon, Overdue, No Entry. The dashboard knows what's required for your vessel type and flags what's missing.

Master Queue & Limited Bridge View

Bridge officers see only what they need — drill entries, inspection forms, and submission. They enter data and submit to the Master queue. The master reviews, approves, signs, and locks entries permanently. Pending count visible in real time. Built for the watch structure, not a desktop.

CFR-Accurate Boilerplate Text

Every drill and inspection entry pre-populated with legally accurate CFR language for your subchapter. Select the entry type, add your specifics — the system generates the correct logbook language with proper citations. No guessing at format or references.

📐

Auto-Calculated Load Line Record

Enter summer load draft, FWA, and TPC in Ship's Particulars once. The system auto-calculates load line marks — distance above or below the applicable mark, port and starboard — for every departure. No manual arithmetic, no transcription errors.

📋

Excel Crew List Import

Upload your existing crew list spreadsheet directly — names, MMC numbers, capacities, all imported in one step. Supports 40 to 600 rows for any vessel size from small passenger vessels to MSC container ships. No retyping 22 names and MMC numbers every voyage.

Complete CG-706B PDF Export

Generates a print-ready PDF matching the CG-706B layout — cover page with dynamic subchapter checkbox, crew list with conduct ratings, all drill and inspection entries, statutory entries. Print, sign, bind, file with OCMI.

From bridge entry to OCMI filing.

Compliance Dashboard

Know what's current, what's due, and what's overdue — at a glance.

The dashboard dynamically adjusts to your vessel's subchapter. Every required drill and inspection tracked with color-coded status. Green means current. Amber means due soon. Red means overdue. No more checking spreadsheets to see if the quarterly SSAS test was logged.

Bridge View & Master Queue

Officers enter. Masters verify. Entries lock.

Bridge officers get a limited view — just the entry forms they need. They submit drill reports, inspection results, and operational entries. Everything queues for the master's review. The master approves, signs, and the entry is locked permanently. No unauthorized edits, no after-the-fact changes.

"Built by a USCG Unlimited Tonnage Master who fills out the CG-706B and hands it to OCMI every voyage — not a software company guessing at what inspectors look for."

The Official Log was built aboard transatlantic containerships running Norfolk to North Europe. Every feature exists because a real compliance gap was identified on a real voyage.

The founder holds a USCG Unlimited Tonnage Master's license and actively sails for one of the largest U.S.-flag operators. This isn't theoretical — it's built from the wheelhouse.

The Regulatory Landscape

The CG-706B is a legal document that lasts 60 years.

46 USC §11301

Any U.S. vessel on a foreign voyage (except Canada) must maintain an Official Logbook on form CG-706B. Vessels 100+ GT on intercoastal voyages are also covered. The USVI counts as a foreign port.

46 USC §11303

A master who fails to maintain the logbook or make required entries faces a civil penalty of $220 per violation. But the real exposure is in casualty investigations — incomplete entries become evidence against you.

18 USC §1001

Making a false statement in the Official Logbook is a federal criminal offense punishable by up to 5 years imprisonment. Accuracy isn't optional — it's the law.

Simple, per-vessel pricing.

Pays for itself if it prevents a single deficiency finding.
