Installation-, operation- and maintenance instructions serve as guides only.
There are many, for 4S un-known, factors such as the presence and location of fuel tanks, and the deck’s strength, thickness and composition, etc. that are important to know.
These conditions affect what actions to be taken, and are beyond our control. It is highly recommended that you consult your boat builder, or a suitably qualified person, to execute the seat mounting installation.

Occupants should always be seated to the rear of the seat, with no gap between them and the seat back.
Sit with your back as straight as possible – S-shaped spine, and avoid the slouching C-shaped spine position.
Foot support should always be firm while boat is moving in rough sea.
Feet should not be hanging. Knees should not be straight.
