ABSTRACT:
The shutter opening device, particularly for pleasure craft hatchways, has a gas spring type pneumatic cylinder which actuates the closing and opening movements of the shutter of hatch. A control rod protrudes from the stem of the cylinder, and a pivoting lever acts upon the rod. A button is used to keep the lever in one of the two positions which either locks the stem in a secured position or permits the stem to freely slide.
