As deck boats have become bigger and broader and pontoon boats have become more powerful, performance-ready and posher, the two categories have drawn closer. Sporty and stylish, deck boats come in a variety of configurations, from sunpad-topped sterndrive power to outboard engines directed by single-side console.
Vacuum forming is a technique that is used to shape a variety of plastics. In school it is used to form/shape thin plastic, usually plastics such as; polythene and perspex. Vacuum forming is used when an unusual shape like a dish or a box-like shape is needed.
Manifold vacuum is a natural byproduct of the way that Otto and two-stroke cycle engines work, which is to say most non-diesel internal combustion engines. When a piston in one of these engines moves down on the intake or induction stroke, the volume of the combustion chamber expands.
