Deck and Superstructure

This is a one piece G.R.P. moulding with substantial gunwales and wide non slip decks incorporating a bevelled toe rail for additional safety.

Fore Cabin

Access to the forward cabin is through a oak door from the wheelhouse with a new sliding hatch over it to provide comfortable access. The cabin includes two V berths 6′ 2″ in length with a folding leaf table that is also used as a berth infill. A deep shelf surrounds the whole of the forward area giving ample stowage space. A bulkhead at the forward part forms the chain locker fitted with a watertight access hatch.

The heads compartment is to port containing a marine WC, hand basin and a cold water tap. 

The galley unit is fitted to starboard and now includes an Avonite worktop fitted with a  hob and inset stainless steel sink with Avonite cover. 

The fuel supply to the diesel hob is connected direct to one of the main fuel tanks. A 240v microwave cooker is fitted as standard. Power for the microwave is via the ring main shore supply connection. An inverter/charger is available on the optional extras list that will enable the microwave and ring main to be used when shore power is not available. 

Ventilation is by way of two vents fitted on the coach roof, a deck hatch and six opening port lights. 

Wheelhouse and Cockpit

The wheelhouse is arranged with the helm seat position to port and a matching seat to starboard for the navigator/crew. 

The hydraulic steering, engine controls and instruments are all mounted in the GRP console. 

The helm and navigator’s seats are fitted on top of the heavily insulated engine covers. These covers hinge back for easy access to service points. 

A lockable oak desk locker is fitted in front of the navigators seat for general stowage of navigation instruments etc. The area under the desk locker is fitted out with a useful oak hanging locker. 

The rear part of the engine covers form seats that optionally may be converted to form two extra berths.  The rear bench seat has a lift out stowage locker to gain access to the steering gear and fuel valves. 

A versatile full canopy with three zipped openings and 6 windows is supplied as standard with the Seaward 23. The canopy is designed to be used in the up position in bad weather to provide a cosy shelter from the elements. In sunny weather the canopy sides can be removed separately and with the rear section rolled up the canopy turns into a sunshade. The hinged stainless steel support frames allow the canopy to be unclipped from the wheelhouse and folded down to stow on the aft coaming. An additional table leg socket is fitted in the cockpit to provide an al-fresco dining area using the table from the forecabin.
