BoatSafe calculates your USCG capacity limits based on your boat's dimensions or capacity plate, then checks your actual load — people, gear, and motor — against those limits. Clear pass/fail. No math required.
The problemMost boaters never check their capacity
Every powerboat has a maximum capacity — for persons, total load, and motor horsepower. Overloaded boats are the leading cause of recreational boating capsizings. The limits are printed on your capacity plate or calculable from your boat's dimensions, but most boaters never check them. BoatSafe checks them for you.
What it does
-
Capacity Plate Support
If your boat has a USCG capacity plate, enter those values directly. BoatSafe uses your plate numbers instead of calculated estimates.
-
USCG Formula Calculation
No plate? Enter your boat's length and beam and BoatSafe computes maximum persons, load, and horsepower using the official USCG formulas.
-
3-Point Safety Check
Checks person count, total load weight, and motor horsepower independently. Tells you exactly which limit you're violating and by how much.
-
Save Boat Profiles
Save your boat and typical crew setup for instant rechecking whenever your load changes.
