Amel Super Maramu 2000
Cockpit Seat Cushion size
View from the top that it is arched and from the front also arched.
From the top, the center section is curved back 4 cm .
From the front, the center is curved 5.5 cm lower, which make the contact surface 57.5 cm, but in my opinion take 56 cm
You will see pictures of the seat suction done by the previous owner, note the velcro strap in the middle.
I forgot to put on the drawing the dimensions of the back seat:
