Models

There are basically 4 types of Seaway 25 - the Mark 1 (commenced limited production in 1978) the Mark 2, the Elite (which commenced production in 1982) and the 787. The hull designs are the same shape, but the cabin and cockpit layouts differ. The Mark 1&2 which are almost identical – different builders, lower cabin, semi-enclosed cockpit, twin quarter berths, and a rudder that is located through the cockpit floor. They run their sheets back to the top of the cabin. With a permanent icebox located beneath the cockpit at the companionway, and a shaped centreboard case on the Mark 1. The Elite - These have a rear hung rudder, a higher cabin (approx 5"10 headroom at entry) and a double berth under the cockpit. Most of the Elites have slightly different layouts, some have V-berths, others none. The cockpits are totally open, and there is no "coaming" around the sides. They are extremely large and wide compared to most other trailer sailers and can seat 6 comfortably. The sheet winches are located on the "seat/side decks". There is a fixed “window” port in each side of the hull. The 787 was primarily produced as a cruiser has a similar hull/cockpit to the Elite, but the sides of the cabin are pushed out giving a more spacious feel inside, but reduced side deck area, not as convenient for racing.

Both the Mark 1 & 2 and the Elites have an open centreboard case, with the keel rising up into the cabin, which supports a folding table. The head is located ahead of the keel case bulkhead. The 787s have a keel that rakes forward (at approx 75 degrees) into the forward V-Berth. The keel is totally encased, opening through the cabin roof. The head is located beside the keel case.
