ELECTRIC CLIPPER 100

— A tough two-container sailing cargo passenger ship for zero emission trading, custom designed for the job.

— An efficient, easily handled yet powerful ketch rig.

— A crew of 3 + passengers

— Twin electric motors with lithium battery banks.

— Solar and propeller generation with back up diesel generators for safety.

— Separate passenger accommodation for four in two cabins with their own galley, head, and shower.

— Shallow 1.8-metre draught to go where few other cargo boats dare.

— A flat bottom with bilge keels to take the ground safely.

— Wonderfully versatile cargo options from a 40-foot container to stacked pallets to container-sized accommodation units – passenger modules or pretty much anything.

— Gaff crane on board to load and unload up to one tonne each swing.

— Every component of the vessel is designed for a long, low maintenance lifespan.

— A four-passenger sailing dinghy with one pallet capacity and electric auxiliary is stowed in davits.

THE SHIP DESIGN

THE RIG

We have used the time honoured gaff ketch rig for good power low down to reduce heeling. It’s an easily manageable and bullet-proof set up. Our modern version features a carbon fibre main gaff, rigged for cargo handling. We will take full advantage of modern sailcloth and tough synthetic cordage. We’ll employ hollow timber masts and set squaresails with carbon fibre yards. These downwind sails will be set like square topped spinnakers – no one gets sent aloft on this ship. There’ll be full cut genoas for those light airs and a roller reefing jib and mizzen. An efficient rig is a cost effective rig.

THE HULL

The hull is to be built in steel for economy, strength, and a long life. With the weight concentrated down low in the ballasted double bottomed hull, the boat will be safe and stable. There will be seawater ballasted “wing” tanks port and starboard for trimming and when lightly loaded. The hull form is of necessity flat-bottomed around the central cargo hold but finely shaped to a knife edge bow and a carefully contoured stern to ensure efficient, easily driven underwater lines. Bilge keels will be fitted so the vessel sits upright when the tide recedes. Twin dagger boards fit inside the bilge keels for enhanced windward performance. Above decks aluminium is used for the wheelhouse and the cargo hold is battened down with tough synthetic canvas supported by aluminium battens on rollers.

THE ENGINES

When the wind dies, twin electric motors will power the ship at a steady 7.5 knots for over 3 days. The brushless permanent magnet motors will be powered by two generous banks of lithium ion batteries which in turn will be charged by the solar array and propeller generation under sail. Separate diesel generators will be installed for backup power.

THE CARGO

Versatility is the key here with a variety of cargoes able to be shipped. The hold will take 2 x high-cube 20-foot containers with a removable central bulkhead to take a single 40-footer. All container sized modules can be stowed and we have designed a two-storey accommodation unit that can also house an office, storeroom, mini laboratory or mini hospital – in fact anything container sized. Either side of the container in the central section are two smaller areas for general cargo or ten pallets. Containers aside, the hold can be filled with anything the traders need shifting and the gaff crane can load up to one tonne on pallets or in a sling. Once battened down, a solar array is unfolded and secured over to ensure the battery banks are kept topped up.

THE CREW

A crew of three is enough to run the ship – a master plus two hands. In order to make their life easier we’ll make full use of good reliable pumps, hydraulic steering, modern winches and up to date electronics with the emphasis on simplicity and efficiency so the crew are able to man the ship confidently in all conditions. The captain will have his own private cabin in the wheelhouse with the crew below decks. A head, shower, and mini galley are provided – look after the crew and they will look after the ship.

THE PASSENGERS

The new ship will also take on four passengers in two cabins in the fo'c'sle. Each cabin has two bunks, lockers and a fold-down table. The foredeck is accessed via a separate companionway which leads to a good sized galley, shower, head, and general store. Dining on deck is via folding tables set up under an awning so the lucky passengers can enjoy those lovely tropical sunsets. Extra passengers can be accommodated in the specially designed two-storey container units with their own self-contained heads, shower, and power supply. These “plug-in” units are accessed from the side decks under mini awnings and feature a double bunk in a separate cabin and a lounge/dining areas. Down below are two more bunks, toilet facilities and services.

SAFETY

The health and safety of the crew and passengers is, of course, of utmost importance so all equipment including anchors, chain warps, sea anchors etc. will be of a good standard and all items such as safety lines, life preservers, emergency life rafts are full compliant to international standards. The ship’s boat also has foam-filled compartments.

Backup generators are also installed. Each motor and each cabin has independent circuitry and battery banks.
