GROSS VEHICLE WEIGHT CALCULATION
Sealegs system, base craft, full complement of fuel, fresh or saltwater reservoirs, grey or black water tanks, flooding keel(s), live bait tank, the heaviest primary water drive engine option and the heaviest combination of any available additional options.
The Maximum Payload Capacity (Weight) for Sealegs equipped craft while on land or when Sealegs system is in use is; [2500kg – Maximum Wet Weight] (as calculated below).
The Maximum Payload Capacity (Persons) allowable is deemed as the [Maximum Payload Capacity (Weight) / 80] rounded down to the nearest integer.
The maximum payload of the craft shall not under any circumstances exceed the calculated figures below, while on land or when the Sealegs system is in use. However, a reduced capacity of persons or weight is acceptable for your craft for reasons of space, safety, seating or similar.
EXAMPLE: Maximum Wet Weight
Sealegs System: 500kg
Donor Hull & Drive: +1350kg
Full Complement of fuel: + 150kg (200L Petrol)
Maximum Payload Capacity (Weight) = 2500 – Maximum Wet Weight
(Persons and gear) = 2500 – 
Maximum Payload Capacity (Persons) = Maximum Payload Capacity (Weight) / 80
=  / 80 = 6.25
= 6 Persons
