The Darkness – in detail

So what’s going to help propel these women to glory in Westminster at Easter 2014?

The first consideration was the weight of the boat. With umpteen portages in a typical marathon and the 77 which have to be negotiated during DW, it is important that the boat is as light as possible to make this easy. So much time can be lost on portages while the paddler picks the boat out of the water, runs the length of the portage and re-introduces the boat to water prior to embarkation.

The Darkness weighs 8 kgs including seat and buoyancy and is quick and easy to get in and out. It also has a comfortable and secure place to grip on the inside of the gunwales.

All boat surfaces were considered for reduction especially the parts which are above the water line. As a canoe doesn’t have the benefit of a rudder, it is up to the paddler to compensate for side winds which attempt to turn the boat towards the wind direction in a similar fashion to a weather cock, hence the term “weather cocking”. So the deck area is low profile.

Straight line tracking is also an important consideration to reduce the number of times the paddler has to switch the paddle to the other side of the boat in order to maintain the intended direction. The Darkness has zero rocker along the length of its hull thus providing excellent directional stability.

The seating and paddler position is crucial to provide a firm, efficient and ergonomic paddling platform. An adjustable solid platform which supports a moulded foam seat, is fixed with four stainless steel bolts and wing nuts between two parallel rails.

It is 7 cms high from the bottom of the boat. Different sizes, shapes and heights of foam seat can be fitted between the upright seat supports which should be able to cater for most people’s “foundations”.

The seat solution also enables a different foam seat to be used during various stages of the DW. For example, a high seat can be used for the canal section where the water is flat and still. The height allows more leverage on the paddle but it does render the boat less stable as the centre of gravity is higher.

A lower seat may be appropriate for the tideway where the paddler may encounter large washes from the Thames boat traffic plus the refracted waves from the vertical sides of the river.

An adjustable footrest is fitted consisting of two aluminium square profile tubes inside each other to provide a telescopic cross member secured on two rails with stainless steel bolts and wing nuts. It is covered with skateboard grip tape to prevent the paddler’s feet slipping along it.

The front thwart provides a really firm and well positioned bar to help the paddler get out of the boat and to lower themselves onto the seat during embarkation. It is wrapped with racing cycle handlebar tape for warmth, comfort and good grip.

Buoyancy is afforded by a 12 litre Palm Infinity airbag in the stern and a 35 lire bag in the bow.

The front deck has quite a steep angle to allow a good sweeping arc for when the paddle is switched from one side to the other and to dispel water if a wave washes over the bow. It rises to meet a flange which forms the gunwale along the top of the entire open cockpit.

As well as dispelling water, it also enables the use of spray decks. An ICF compliant open cockpit must be at least 2.4 metres long and the gunwales must not extend in towards the boat greater than 5 cms. This means it is a quite a large open area into which rain, spray and water dripping from paddles can enter the boat. A spray deck front and rear reduces the impact.

I’ve left the most important design consideration to the last; “as everyone knows” to achieve ultimate performance the boat must look cool!

There are some fantastic looking vessels on the water but most rely on pigmentation in the construction to “hide” the imperfections inherent with carbon composite manufacturing processes and they do look pretty. The Darkness is naked of all cosmetic embellishments and is a celebration of the profound beauty of carbon fibre. It is stunningly beautiful and proud of its dark sleekness.

The Darkness - in all its glory!

Have we thought of everything? Probably not but any short comings will be uncovered during DW.
