A cuddy cabin boat has a fixed, solid foredeck or “roof” with an opening deck hatch for ventilation over the dedicated sleeping accommodations below. Cuddy cabins (cuddies) range from eighteen or more practically, twenty feet at the smallest to about twenty-eight feet at the upper end although even bigger cuddies up to mid-thirty feet are available and at this size, are sometimes referred to as weekenders.
A cuddy by definition provides a fixed or convertible berth in the bow area suitable generally for two persons only. This berth may be convertible into a dinette. Often a head (toilet) is provided under the center section of this berth in the smaller cuddies. As the cuddy increases in length, more headroom is provided (but rarely full standing headroom) and more interior room is available for additional amenities such as a separate enclosed head on one side of the cabin and perhaps a sink with running water and/or storage cabinets and/or galley with refrigerator and/or cookstove on the opposite side. Cockpits of cuddy cabins often mimic those available in a similar sized bowrider of the same manufacturer and camper back (full stand-up, squared-back) canvas enclosures for the cockpit are usually available. A few smaller cuddy cabin boats are outboard powered but most are sterndrive powered. The exception to this rule is in the case of “Offshore and Big Water Fishing Rigs” which often provide an enclosed cuddy and almost all are outboard powered.
