There is ample sitting headroom for 4 and a filler cushion that drops to form a 6'6" v-berth that is NOT broken up by the usual awkward mast support post. There are 6' quarter berths port and starboard, not to mention a 48 quart cooler, provision for a portable head, and 12-volt battery. A forward hatch provides ventilation and an emergency exit, and the large companionway and 4 opening cabin windows contribute to the feeling of light and open space. Carefully controlling construction weight is critical to both performance and to price, but it cannot be done at the expense of safety or structural integrity. Thus the hull liner of the Precision 18 is engineered as a structural grid, and tooled to mate precisely with the hand-laminated hull skin. The mast support beam and chain plate loads are carried by structural bulkheads and there are rugged hull stringers to distribute the stresses imposed by trailering. The external hull/deck joint is bonded both chemically and mechanically, and the flange is protected with a vinyl rub rail. The Precision 18 has been kept small in size and price, but remains big in both features and performance. She promises to deliver the fun, pure and simple!
