Keeping your boat shipshape!
Battery & Electronics
Track the gear that keeps your boat alive — and size your wiring so it never dies at the dock.
"Battery dying" is one of the most-searched boat problems. Track what you have, when it was bought, and its health here — saved in this browser.
Voltage drop & cable sizing
Long, undersized runs lose voltage. Keep the drop under 3% for critical gear. Estimate it with the app’s calculator, then size up a gauge if needed.
Battery life
Most marine batteries last 4–5 years. Write the install date on the battery and log it here — age is the №1 cause of “dies at the dock”.
