Capacity-plate check
Type the person and weight limits printed on the boat, then your group size, an average weight you choose, and the gear. The only official limits are on the plate.
What this does — and does not do
People left = plate people − your group. Weight used = people × the average you typed + gear. Weight left = plate weight − weight used. Four people at 80 kg with 40 kg of gear is 360 kg; against a 6-person, 450 kg plate, that is two person-spaces and 90 kg left, under those assumptions.
This is not a substitute for the capacity plate, for a lifejacket count, or for the operator’s own rules. It does not rate a hull, and it does not know the weather. If the plate is missing or unreadable, do not guess: ask the operator and do not load the boat past what they will allow.
