Coupe powerboats with a fully enclosed pilothouse are small to mid-size motor yachts, typically 8–14 metres, in which the helm and saloon are enclosed by a lockable cabin structure with solid doors and full side glazing, while a separate aft cockpit remains outside this enclosed volume. The arrangement provides a sealed, weatherproof interior that can be left secured when the boat is unattended at a marina berth.
The fully enclosed pilothouse offers reliable all-weather protection — the helm and saloon remain dry and comfortable in rain, cold, or strong wind — which makes this configuration practical for northern European and other markets where weather exposure is a regular consideration. Heating systems integrated into the saloon extend the usable season. The trade-off is deck access: on smaller examples, moving between the cockpit and the pilothouse requires going through a door, and the divided layout makes the boat feel more compartmentalised than open or semi-enclosed designs of comparable length. Ventilation in warm weather requires deliberate management through hatches and opening windows.
Construction is GRP sandwich; the pilothouse and hull are produced as separate mouldings joined at the deck. Accommodation below decks typically includes a forward double berth, a heads compartment, and a compact galley — adequate for weekend coastal cruising. Propulsion is inboard diesel with shaft drive or sterndrive; single-engine installations are common on smaller examples, twin engines on larger builds above approximately 11 metres.
