Past Data Lets You Accurately Predict Future Possibilities
Log Book for Your Boat is a digital voyage log built into your YachtWatchCare membership. Every reading you enter while underway — engine RPM, exhaust temperature, oil pressure, fuel and tank levels, position, and weather — builds a continuous history that turns into clear trends and charts. Reading that history is how you catch a slow-rising exhaust temperature or a dropping oil pressure days before it becomes a breakdown at sea, which is exactly why keeping the log current during every passage — not just once back in port — matters most.
It is offered completely free to every YachtWatchCare customer, with no extra fee and nothing to install. Your complete record can be printed, exported as a CSV file, or copied straight to a USB drive in seconds, so a full offline copy of your boat's history is always yours to keep.

Why It's Worth Filling In Every Trip
Free for Every Customer
The Log Book is a free voyage companion included with every YachtWatchCare membership — no extra fee and no separate app to buy.
Catch Problems Before They Happen
Continuous engine, tank and generator trends let you spot a slow rise in exhaust temperature or a drop in oil pressure days before it becomes a breakdown at sea.
Built for Use While Underway
Quick, simple entry fields are designed to be filled in during a watch, at anchor, or right after a passage — so your log stays accurate, not reconstructed from memory later.
One Click to Export
Print a clean report, download a CSV, or copy your full digital archive to a USB drive in seconds — your records, always yours to keep offline.
An Audit Trail You Can Trust
Every entry and edit is time-stamped and preserved, never overwritten — a trustworthy history that stands up with insurers, surveyors, and marine authorities.
Protects Your Boat's Value
A complete digital service and voyage history is one of the strongest things you can show a future buyer — proof of care, not just promises.
