Seaward Sapphire is a classic Nelson motor yacht. She was built in 1991 by Seaward Marine on a Tyler moulding to exacting Nelson specifications, with heavy GRP laminate, substantial ribs, stringers and engine bearers, and heavy duty fittings throughout. This vessel is from an era when expense was not spared, and boats were built to last. As would be expected, the fit-out was to the highest standard, with beautiful teak cabinetry throughout.

Seaward Sapphire – specification

The Nelson 45 was designed as a fast semi displacement, exceptionally robust, all-weather pilot vessel. Its lovely lines – fine entry, flared bow, round bilge, flattened stern and long skeg give it unrivalled seakeeping qualities and safe passage making (see Tom Cunliffe: )

The boat was purchased by the present owners in August 2018. On receipt at Pwllheli the vessel, although sound, was found to need considerable upgrade. A significant refit, restoration and modernisation is at point of completion.

Machinery installation

Engines: a pair of Sabre Lehman type 370L turbo charged 6 cylinder straight diesels coupled to MG 507ATwin Disc gear boxes. Port engine serial no. B9137, hours logged 1209. Starboard engine no. B9138, hours logged 1218.

The engines are installed in an enclosed engine bay beneath the wheelhouse, accessed via a floor hatch with gas lift. The engines have flexible engine mounts bolted to substantial glassed-in longitudinal engine beds. Cooling is indirect via raw water heat exchangers, with heavy duty bronze raw water intakes fitted with strainers. The wet exhausts discharge as follows: main exhaust pipes port and starboard through underwater outlets, with smaller diameter exhaust pipes discharging at the waterline level. This ensures that exhaust back pressure is minimised when the engines are idling.

Kobelt 2090 remote controls are fitted at the wheelhouse (main station) and at the upper helm (slave station), with a control panel and warning gauges for each engine at both helm stations.

Steering Gear: located in the aft cabin steering locker. A pair of stainless steel rudders are fitted through glassed-in tubes with lip seals with remote greasers.

The dual helm consists of hydraulic pumps attached to each wheel, plumbed with copper and then flexible hose connections to the hydraulic ram.

Provision is made for emergency steering in the event of hydraulic system failure, which includes access points through the top of the steering locker, through the head lining (with teak closer, labelled accordingly) and out through a labelled screw cap in the aft deck. The necessary drive rods are stored under the aft cabin bed base boards.

Stern Gear: 3-bladed 26”x27” bronze propellers are fitted to stainless steel 1¼” stainless steel shafts run through cutlass bearings contained within bronze P-brackets and then through water lubricated intermediate cutlass bearings within the stern tubes. The shafts are sealed through grease packed stuffing glands.Spurs rope cutters are fitted forward of the props. New shaft and rope cutter anodes are fitted.

Generator: G&M 4.2Kva generator set is installed within a sound insulated steel casing at the aft end of the engine room. It is powered by a Volvo 2001 direct raw water cooled single cylinder diesel engine running at 3000rpm to generate 230V AC. Fuel is drawn from the aft keel tank

Generator starting is via a 12V dedicated generator starting battery with isolation switch and is independent of the main battery banks. When running, the generator battery is charged as normal by the generator’s alternator, but to avoid self-discharge during prolonged periods of inactivity, there is also a Victron Orion battery -to-battery charger supplying the gen set battery from the main port battery bank.

The wet exhaust system incorporates a Vetus water lock, muffler and gooseneck, and discharges through the starboard topside at the waterline level.

Bow thruster: a Max PowerCT60 twin propeller 24v bow thruster is installed under the forward V berth. It is powered by a pair of 24V batteries fitted under the forward cabin berth in a compartment vented by the bilge ventilation system. The circuit is protected by an overload fuse and master switch.

Joystick controls are fitted at both the lower and upper helm.

Fuel installation

2 in-line GRP keel tanks are moulded into the vessel, situated between engine bearers, each engine being independently supplied by its own dedicated fuel tank. These keel tanks are gravity fed by elevated port and starboard tanks in the aft cabin and controlled by appropriate isolation and cross-pipe valves.

All tanks are fitted with tank breathers, opening to the topside port and starboard, and the tanks are filled from labelled fillers situated in the port and starboard side decks and connected to the port and starboard aft tanks only.

The fuel system pipework is copper and fuel grade hose and incorporates a substantial Racor filter/fuel separator to each engine, with a fuel gauge to each tank. There are also two engine mounted fuel filters per engine.

Freshwater installation

Two GRP freshwater tanks are moulded into the forward bilge. These are filled via a labelled filler cap in the port forward side deck and vented through the forward topside. They are connected to a 24V Cleghorn Waring Maxi System pressurised pump system which supplies the hot and cold circuits throughout the boat.

There is a separate independent deck-wash system, as well as screen wash, also supplied from the freshwater tanks.

Hot water is provided by an ASAP 55ltr Hotpot calorifier heated by 240V immersion heater and the diesel powered heating system. There are connection terminals fitted to the starboard engine’s cooling system should this be required.

Ventilation system

ACS stainless steel mushroom vents are fitted to all accommodation spaces, except for the ensuites which have switched extractors. Additional switched extractors are fitted in aft and fore cabins.

Bilge extraction is installed throughout the boat, with a 240V extraction fan located in the engine room port aft and discharging through the wheelhouse side via a stainless steel grille (a 24V fan could be substituted). This system also vents the bow thruster battery compartment.

The engine room is ventilated through characteristic Nelson air intake cowls to port and starboard in the wheelhouse sides, with two 24V blowers switched as required from the helm.

Gas installation

All gas appliances and pipework removed but the external gas locker remains on the port side deck

Heating

Space heating is provided by a 5kW MV Hydro 24V diesel heater, installed in the engine room starboard side aft. This supplies a 22mm speedfit heating ring main serving six Kalori Silencio matrix heat exchange units with 24V fans to: fore cabin, forward ensuite, galley, wheelhouse saloon, aft cabin, aft ensuite. Each zone is controlled by a Heatmiser thermostat control panel.
