Construction. The all glassfibre Seal is moulded in our modern, temperature controlled factory. Hull lay up consists of the gelcoat followed by a layer of 1½ oz mat, then a 2 oz layer of mat, a single layer of 18 oz woven roving and a final layer of 1½ oz mat. In addition, there is progressive thickening from the waterline to the keel and at the bow. Great hull rigidity is achieved by bonding in fore and aft stringers and the interior moulding, which forms the berths and toiIet compartment. The deck, coachroof and self-drain cockpit form one moulding which is bolted and bonded to the hull. Non slip deck surfaces are moulded in.
Keel and rudder. The retractable keel is a heavy iron casting of approximately 800 lbs (367 kg) weight. It is hydrodynamicalIy shaped and fits snugly into glassfibre housing. The simple screw jack lifting gear is easy to operate. The rudder has anti fracture marine ply cheeks, stainless steel hangings and 5/16" (7.5 mm) mild steel blade.
Rig. The Seal is a Bermudian sloop. Mast and boom by Ian Proctor Metal Masts Ltd. are gold anodised. Stainless steel rigging consist of upper shrouds with swinging spreaders, and lower shrouds and forestay. Halliards are prestretched terylene. Sails are 5 oz terylene.

Other pictures show various aspects of life aboard the Seal: the galley, with ample lockers and shelves, is to starboard; hanging locker is to port; just visible is the up and over door which completely encloses the fore cabin, for privacy and security. The sea, or chemical, toilet, fits between fore cabin berths; normally it would be hidden by hatch and cushion.
Picture, right, second row, shows the boat high and dry with the legs in place; these are easily fitted to the hull for slipping and laying up. Because, when the fin is housed, she has only a small stub keel, the Seal will take a mud berth upright.
Happy young Seal sailor is winding up the keel at the end of a day's sailing; the simple screw jack is mounted atop the keel housing, under the table, handle can be removed. The passengers are separated from the helmsman by the bridge deck; on which runs the centre mainsheet. Note how deep and secure the family are; the aft, self-drain cockpit, has high coamings.
