Author’s Note

Over the winter of 2006-2007 the owner of Discovery made major improvements in electronics,

replacing or adding the Radar, GPS, Ploer, Weather Staon, Hailer, and CB Radio; a Spectra

Watermaker was also added. These new units are illustrated in the secons of the manual specically

discussing them, however some of the wide-angle pictures of the boat show the old units. Thank you for

your understanding!

Secon I: Introducon & General Boat Descripon About This Manual

Manual Objecve and Limitaons

This manual is intended to introduce you to “Discovery”, its systems and features, allowing you to operate it with the

condence and self-assurance necessary to enjoy your cruising vacaon to its fullest. It is not intended to replace a basic

understanding of seamanship, including navigaon skills, weather interpretaon or boat handling. You are expected

to have an understanding of these subjects obtained through other sources, including training, seminars, reading and

perhaps most important, experience.

There is no way that a small manual like this one can answer every queson or give you a soluon to every circumstance,

foreseen or unforeseen. If you have a queson which limits your understanding or handling of this vessel, ask your NWE

checkout skipper or contact the oce for details (you might make a list of quesons as you read the manual, saving them

all up to ask at one me).

How the Manual is Organized

The tab for each secon denes its general purpose as shown on the front page.

You will use Secon 3, containing checklists, most of all. You should have it available so that each checklist can be used

on a daily basis, even aer you are familiar with the boat.

Secon 6, regarding Emergency Procedures, is the most important, and you should read it, but hopefully you will never

need it.

Read this secon rst to learn about this manual and the general details of your boat. The other secons will tell you

most of what you need to know to enjoy your cruise to the fullest with safety and condence.

General Descripon of This Grand Banks 46’ Classic

Exterior

The Grand Banks 46’ Classic is a tradional yacht design,

with berglass hull, cabin, and ybridge structures, a teak

swim grid/step, teak decks, rails, and gunwhale caps, and

stainless steel welded ngs and handrails. The window

frames are of painted wood with sliding glass panes,

while the windshield frame is of the same material.

Of parcular note are the easy walk-around decks,

enabling safe, secure passage about the boat by

passengers and crew. A roomy cockpit secon with a

storage lazaree beneath is especially useful for shing

and for handling the dinghy aer it is launched from its

davit on the stern.

On the side decks are the two fuel lls, one port-side and the other starboard. A holding tank pump-out deck ng is

located on the port side a. The water tank lls are on the port side, in the side and foredecks.

The roomy walk-around helps

keep you safe and secure. A view of the cockpit. Aft shore power

connection by door; shower foreground.

NW Exploraons DISCOVERY OPERATING MANUAL | 5

Forward on the bow deck is the anchor windlass with foot switches

allowing chain movement both “up” and “down” electrically. The

anchor is retracted into the bow pulpit which hangs out over the bow

to give beer chain clearance from the hull than otherwise possible;

this pulpit is strong and braced, easily supporng not only the anchor

during hauling but also an aending crew member if necessary. Aer

passing over the winch, the chain goes below decks via a hawse pipe in

the foredeck.

There are shore power connecons (with an adjacent fuse holder) at

both the bow and stern, selected by the shore power switch in the

electric panel; when this cable is to be disconnected, the switch

should rst be turned to the “o” posion to avoid arcing which could

damage the plug contacts. The boat’s 30-amp shore power cable is 50 feet long and stays with the boat when away from

its home dock. An addional 30-amp cable is located in the starboard bow locker.

Three steps above the a side

decks is the “boat deck”. Here

you will nd the permanently

mounted barbeque with its own

xed propane tank, as well as

a professional electric davit to

which is aached a hard- boom

inatable dinghy with a Honda

outboard engine.

Up three steps from the boat deck is the ybridge, with seang for crew and

passengers, and the upper helm staon. In addion to the helm’s instruments

and controls, the console has storage for the ship’s canvas covers and a space for

ybridge electronics. Within the storage compartments beneath the seats you

will nd a complement of life jackets (on the starboard side) and the propane

tank for the ship’s stove (to port).

Bow pulpit, windlass, & shore power connection.

The barbecue and its tank (here in their

canvas covers) are on the boat deck handy

to both the main deck and the ybridge.

In this view you can see the mast with radar

and spreader lights and forward, the Bimini.

The ybridge has comfortable tandem

seats with storage beneath plus

a full helm station.

The L-settee on the ybridge will be

a focus for your evening relaxation

after cruising.

Interior Accommodaons

The boat is entered by either side door, port or starboard. These doors are ed with strong deadbolt locks, and in

addion have stainless catches axed to the cabin sides to hold them open; these “hold-open catches” should be

engaged manually, not just by “slamming the doors open” to avoid damage to the catches by bending, or the doors by

banging. The doors should be closed when underway except at very low speeds in calm waters to avoid geng salt water

inside the doorways. The starboard and port door steps have storage beneath for shore power cord adapters, ashlights,

re exnguishers, etc.

Just forward of the starboard door is a professional-quality helm staon with electric switch panels adjacent and

electronics panel above; on the helm itself are the ship’s radar, and GPS/ploer. In the helm cabinet is storage for

manuals, de tables, navigaon tools, charts, etc.

A of the starboard door is the custom helm seat with three drawers and a cushioned top. Just a of this is a dry bar

with an icemaker below. A of the icemaker cabinet is ed an L-seee to starboard. Under this seee’s forward end are

stored the boat’s engine spares; in the next cabinet a under the seee is the vacuum cleaner. The seee a-end drawer

has emergency gear (see following secons). A table in front of the seee is used for dining/cocktails.

To port is the entertainment center with

sidechairs and a book/magazine rack.

Moving aft from the bar is the L-settee

with the table in front and cabinets below.

Looking forward to the helm, helm seat

with drawers, and dry bar with icemaker.

NW Exploraons DISCOVERY OPERATING MANUAL | 7

The table has storage inside it for

games, cards, and other miscellaneous

items, and below it for boles and

magazines.

To port in the salon is more

seang, with two side chairs by the

entertainment center which has a TV/

DVD and stereo system. The ship’s

manuals are in the a cabin. Forward

by the port doorway are swivel bar

chairs.

Down from the salon to port is the

U-shaped galley. It has a propane

stove/oven in the counter; a large

stainless sink on the a counter;

deepfreeze (right of sink) and a

microwave. There is extensive storage.

A storage hold is in the galley oor.

The stove burners have a push- buon

“igniters”; the oven re- quires manual

pilot-lighng (a “propane match”

galley).

The forward stateroom includes a

V-berth with insert, a hanging lock-

er, and drawers/ cabinets for crew

clothing. A large overhead hatch and

side opening portlights provide plenty of

light. Moving a from the stateroom to

starboard is a locker housing the ship’s

washer/dryer; then the forward head

compartment with its own stall shower

and Vacu-ush head and basin with van-

ity. Both the stateroom and head have

oor storage holds.

The a (master) stateroom is down a

few steps from the port end of the salon.

Forward to port in this stateroom is a

head compartment with toilet, sink/van-

ity, and numerous cabinets and drawers;

to starboard opposite in the cabin is the

stall shower. Between these two com-

partments are a huge hanging locker for

clothing and the salon passageway. There

is a queen-sized island berth, beneath

which are drawers including a spacious

chart drawer. To each side of the berth

are tables with cabinets beneath, as well

as storage lining the vessel’s exterior

walls on each side. A dresser is a to port

beneath the emergency exit hatch.

The rest of the galley itself: The stove,

cabinets, and the double-door fridge.

In this galley picture you see the

microwave,the sink, glass rack, and un-

der the hatch to right, the built-in

deep freeze and dish racks.

Engine Room

Preferred access to the engine room

is through the oor hatch by the

entertainment center in the salon.

Engine room lighng is turned on by a

breaker in the ship’s DC power panel.

The engines are to each side, while

forward of the engines are their sea

strainer/seacocks, the sea strainer for the

refrigeraon system, the vacuum pump

for the forward head, lters for the

watermaker. On the forward bulkhead

of the room are wiring terminals and

the ship’s inverter. Outboard of the

engines to starboard are the ship’s

furnace, watermaker, and two baeries;

to port are the fresh water pressure

pump and accumulator tank, the water

heater, refrigeraon compressors, and

two more baery boxes.

Just a of the engines outboard are

the two fuel tanks, with sight gauges

for fuel levels (the valves at each end

of the gauge for safety must be opened

for a tank reading). A of the engines

midships is the Northern Lights

generator in its sound shield; and to

each side of it are the main engine

Racor primary fuel lters. To starboard

of the genset are the oil change pump

and a set of controls for the genset.

To port of the genset is its sea strainer

and Racor, the a head vacuum pump

and accumulator tank, and the genset

muer. The engine shas lead from the

transmission couplings through the

hull via virtually maintenance-free sha

logs/packing glands. Just forward of the

genset midships is a fuel manifold panel

(which requires no operaon under

normal circumstances) and beneath the

genset is one of the ship’s two water

tanks; the other is forward.

Right over the middle of the port engine.

The water pressure accumulator tank

to right (the refrigeration compressor is

forward of it), thewater heater, and the

synchronizer unit.

Forward, just to port: The inverter above

its battery switch. To right, a water

faucet. To left, the refrigeration control

box, and underneath a battery box.

In the center aft engine room you

see the white genset box; the fuel

manifold with its valves, and the fuel

lters for each engine. The genset

battery is outboard of the port engine.

Looking over the top of the starboard

engine aft of the wiring panel: we see

the heater system and its various

hoses. Note the asbestos-wrapped ex-

haust going out the starboard side:

we talk about this under “Furnace”

later in this manual.

Looking to starboard at the forward

end of the engine room. You see the

battery switches (foreground) a head

systen vacuum pump, the battery

charger and the wiring panel,

and the steering cables.

Looking aft of the starboard engine

there is the starboard fuel tank with

its sight gauge; a set of generator

controls, and the sound shield

around the generator.

NW Exploraons DISCOVERY OPERATING MANUAL | 9

In the engine room is a supply of extra lube oil, baery water, spare parts, oil pads, etc.

Dinghy

The boat is equipped with a 10’ AB RIB-inatable dinghy with 15hp Honda 4-stroke outboard motor, fuel tank, pump and

oars.

Deck Equipment

The boat has mooring lines; a stern/shore line at least 200’ long; an appropriate all-purpose anchor with at least 360’ of

all-chain rode plus an emergency anchor with chain and rope rode; fenders/bumpers; four deck chairs; an ice chest; a

crab pot or ring with line, oat, and bait rigging; a hose for fresh water tank lling and boat washing; and a boat hook.

Safety Equipment

This vessel is equipped with three fire exnguishers, one each in

the forward stateroom and a stateroom and another in the port

interior side door step; a ship’s bell; ares; an appropriate supply of

life jackets; and VHF radio. Charter clients with children under 90

pounds should bring appropriate life jackets for them.

An engine sea strainer. See the long

yellow handle on the right? The “T-knob”

referred tolater in this manual is hidden

on the opposite side of the strainer.

Look just aft of the fuel lter: See

the loop forming the dipstick handle?

You can also seethe coolant cap clearly

atop the tank. The black “bump”

just left of the coolant tank is the

emergency stop button.

The port engine. Note the coolant tank

on the forward upper end; the yellow

“can” is the secondary fuel lter.

The white knob on the front end

is the fuel priming pump.

On the aft side of the aft ybridge rail is the lifering,

easily accessed from either the ybridge

or the boat deck. A second lifering is located behinfd the

seat on the ybridge settee.
