Getting Started

Overview

SeaLog records and organizes sea service for mariners preparing an OUPV (Operator of Uninspected Passenger Vessel) application. You can record live trips, add historical service, and manage records across multiple vessels.

What to do

Add your vessels. From the Home screen, enter the details for each vessel on which you record service.
Choose a default. Set your most frequently used vessel as the default, and check that the correct vessel is assigned to each trip.
Enable location access. Allow SeaLog to use location services to record GPS positions during live trips. Then start recording or use Importing Trips to add an existing history.

Important details

Vessel details remain editable. Keep names and particulars accurate; changes to a vessel are reflected in its associated trip records.
Free and Pro features. Trip logging, vessel management, qualified-day tracking, CSV import/export, and backup/restore are available without Pro. PDF, KMZ, and GPX exports require SeaLog Pro.
Your record is stored on your device. No SeaLog account is required. Set up a backup routine before relying on the app as your only copy.

Recording Trips

Overview

A live trip records elapsed time and, when location services are available, GPS history. Conditions are captured automatically, and you can add to that record during the trip.

What to do

Start recording. Tap Start Trip when underway.
Watch the live status. The active-trip screen shows elapsed time and GPS activity, including current location, reported accuracy, recent updates, and the number of saved GPS points.
Review conditions. Open the conditions record to review automatic captures. Use the conditions controls to add a record, and add observations or context in your notes.
Leave the trip running. You can use other apps or lock the device without ending the trip. If you force close SeaLog your trip is preserved on restart, but the GPS won't record a track.
Finish and review. Tap End Trip when your service ends. Trip GPS recording stops; open the saved trip to complete its details.

Important details

GPS activity is not the same as saved points. SeaLog evaluates incoming locations and retains selected points. An efficient selection of used points record the trip.
Conditions form a history. Automatic captures occur at the start, at hourly intervals, and at the end of a trip when suitable location and environmental data are available. These are modeled conditions, not measurements from instruments aboard your vessel.
Availability can vary. Conditions depend on location, connectivity, and data availability. GPS recording depends on permissions, reception, device power, and operating-system restrictions. SeaLog attempts to access conditions when the network is restored and the app is running.
After an interruption, review the trip. Reopen SeaLog and check recovered timing information. Locations not recorded while the app was stopped cannot be reconstructed.

Reviewing & Editing Trips

Overview

Complete trip details turn a time record into a usable service record. The Trips screen organizes entries by year, month, and day and shows which records need attention.

What to do

Open the record. Select a recent trip from Home or find it on the Trips screen.
Complete the required fields. Check start and end dates and times, vessel, route category (waters), named water bodies, your role, and the attester's name and role.
Add supporting details. Record useful notes and attester contact information, and review the trip's conditions and GPS history where available.
Save and check the result. SeaLog recalculates after edits. Review the trip status and credited service dates.
Add missed service. For a trip not recorded live, create a trip and correct its dates, times, and details to match the actual service, or use CSV import for a larger history.

Important details

Category and place names are different. Route category identifies Inland, Near Coastal, Oceans, or Great Lakes service. Water bodies identify the actual waters and geographic locations visited.
Use consistent wording. Keep vessel names, water bodies, roles, and attester names consistent. Variations can create repetitive report entries or separate signature blocks. Keep water-body descriptions concise enough to fit the report.
GPS history is read-only. Editing trip details does not rewrite recorded points. Manual entries do not recreate historical routes or conditions. For imported-time restrictions, see Importing Trips.

Qualified Days

Overview

SeaLog uses a four-hour threshold and complete required information to identify qualified days in the app. Recorded hours and qualified days are different totals: a saved trip may contribute time without qualifying a day.

What to do

Review the daily total. Check all trips on the date, not just one entry. For example, two eligible two-hour trips can combine to reach the four-hour threshold.
Resolve status messages. Complete records marked Missing Info. For Under Threshold, check the day's combined time and verify dates, times, and AM/PM entries.
Check overnight service. Open Trip Details to review the dates receiving credit. Crossing midnight does not automatically create a second qualified day.
Recheck after corrections. Resolve unintended overlaps, duplicate records, or import errors, then review the updated totals.

Important details

GPS is optional for qualification. GPS points and conditions are supporting records, not requirements for SeaLog's qualified-day calculation.
One day per calendar date. SeaLog combines eligible trips but does not award a second day simply because more hours were recorded on the same date.
Overnight carryover is conditional. For eligible continuous overnight trips, pre-midnight time that does not qualify the first date may be applied to the following date. The same service time cannot be credited twice.
App status is not Coast Guard approval. The general service-day definition is eight hours; qualifying small-vessel operating schedules may use shorter days of at least four hours. See 46 CFR 10.107.
Check the applicable requirements. Use the current NMC OUPV checklist for total-service, route, and recency requirements. SeaLog's recent-service counter covers the period labeled in the app; it is not a substitute for that checklist.

Importing Trips

Get the Import Key

Overview

Use CSV import to add service recorded outside SeaLog. The import adds trip records to your existing log; it is not the same as restoring a full backup.

What to do

Prepare and back up. Export a backup, then add the vessels needed for the incoming records. Match vessel names exactly.
Use the template. Open CSV import from the Home screen and use the template provided. Follow the SeaLog Import Key for column names, date formats, and accepted values.
Enter the history. Include service dates, durations, qualified service dates where applicable, vessel names, water bodies, roles, and attester information as directed by the template.
Import and review. Correct any errors identified by SeaLog. Check the imported trips and totals before importing the same file again.

Important details

Use hours for duration. Decimal values are supported. Follow the template's date format rather than relying on your spreadsheet's display settings.
Imported time must be consistent. SeaLog validates required content and recorded durations, including the 24-hour limit for a service date.
History is not a live track. A duration-only import does not create GPS positions or historical conditions. Its service dates and durations are not editable as live-trip timestamps.
Check for duplicates. An import does not replace your existing trips. Review accepted records before repeating an import after an error.

Exports & Reports

Overview

Choose an export according to its purpose: CSV for reviewing data, PDF for presenting sea service, and KMZ or GPX for working with recorded tracks. A full backup is a separate function.

What to do

Choose the scope. Open Trips for whole-record exports, or Trip Details for an individual trip's exports.
Choose the format. Use the options below and save the exported file where you can review or share it.
Check before signing. Review vessel details, service totals, water-body descriptions, and applicant and attester sections. Use CSV to locate problem entries, correct them in SeaLog, and regenerate the report.
Complete the packet. Obtain the necessary signatures, retain the original signed files, and follow the NMC's current submission instructions.

Important details

CSV - Free. From Trips, export all trip records for spreadsheet review. From Trip Details, export one trip with its GPS data or a GPS-only list for mapping.
PDF - Pro. From Trips, generate a sea-service report packet organized by vessel, with a summary and applicant/attester signature sections. It supports documenting service; it is not an official CG-719S form.
KMZ - Pro. From Trips, export recorded tracks for Google Earth or other compatible software. A trip needs sufficient recorded GPS data to provide a usable track.
GPX - Pro. From Trip Details, export an individual track for a compatible mapping app or chartplotter. The receiving device determines how the file is imported.
Average distance offshore. SeaLog does not currently calculate this value automatically. Recorded tracks can support your assessment for each vessel; enter the required information when preparing the report.
Signatures. The report supports printed signatures or electronic signing in appropriate software. Preserve signed originals and check signature validity before submitting. You may not alter or merge any digitally signed PDF without undoing the signature lock.

Backups & Restore

Overview

A full SeaLog backup is the recovery copy of your app record. Keep it outside the app so it remains available if your device or local data is lost.

What to do

Export a full backup. Use the backup export on the Trips screen.
Keep an external copy. Save a dated backup to storage outside the app, such as cloud storage or a computer. Keep more than one version.
Back up before major changes. Create a fresh copy before a large import, bulk corrections, clearing data, changing devices, or reinstalling SeaLog.
Restore and verify. Choose the intended backup and follow the restore prompts. Review the restored trips and totals before recording new service.

Important details

Restoring replaces data. Records currently in the app but absent from the selected backup will be lost. Export the current record before restoring another copy.
CSV is not a full backup. CSV exports are useful working copies, but use SeaLog's backup file to restore the app record.
Clear All Data removes trip records. Your vessels and default-vessel selection are preserved. Export a backup before using this control.
Local recovery is not an external backup. Automatic recovery features and device backups do not replace a separate, accessible SeaLog backup file.

Limitations & Support

Overview

SeaLog organizes the information you record. It is not a US Coast Guard product, is not endorsed by the Coast Guard, and does not independently verify that claimed service occurred.

What to do

Confirm current requirements. Consult the National Maritime Center before preparing an application.
Retain supporting records. Check every service claim, obtain appropriate attestations, and keep the material needed to explain your record.
Contact support. Email support@bluetiefpunkt.com with your SeaLog version, device/operating system, and a description of the issue. Include a screenshot or error message when useful.

Important details

Acceptance is a Coast Guard decision. Reviewers may request additional information or assess the service differently from the app's calculations.
Not a navigation or weather-safety tool. Use appropriate charts, forecasts, instruments, and operating judgment rather than SeaLog's trip records for those purposes.
