The boat as may be seen from the pictures is being built in an arch rented from London Transport and the rumble of tube trains goes on over-head. The arch fronts on to a narrow alley way into which there is access through a large shuttered door.
Exiting and handling the weight of the craft when it is finished onto a low loader or trailer will be adequate but tight provided its keel is not attached.
It is the design of and the making of that keel that now poses some difficulties
- secure and watertight attachment to a ‘paper’ thin bottom
- a frame onto which a mechanism for adjustable weights in the bulb is provided
- and a general profile that embraces the reversed tear drop concept.
The hull is 2mm thick marine grade aluminium, not the heftiest to take the weight and twisting moments of 300 kg keel.
The weight will be taken by spreading the load on 10mm plates on the boat’s bottom and the twisting moment by projecting the keel well into the centre of the hull and laying off stresses there to the hull sides by means of bracketing.
