Very neat execution by Ray Joyce of an experimental ‘mode’ control system. It closes the exit of the mainsail automatically when the boom is on centreline. This allows a standard ‘open’ setting for acceleration and reaching to change into ‘pointing mode’ once the boat is up to speed close hauled. The standard four rigs are...Read More
Carbon/foam sandwich jib booms were chosen to maximise jib efficiency and allow ‘finite’ adjustment arrangements using notches and pin/hole systems. The jib boom swivel line goes through a fairlead in the top skin of the yard and is anchored through the bottom skin. This is to maximise length for the required twisting of the line....Read More
Just something in the pipeline… We want to get this right so the testing will continue until we are confident that meaningful gains are possible. In the excitement of a new project we must remain clear and resolute about our aim and why we are doing what we are doing!Read More
More very interesting aerospace work. Unfortunately details are confidential except that this is a (discarded) model for wind tunnel evaluation… The experience we are gaining in this field has fantastic applications in boats and other vehicles, not to mention commercial drones.Read More
The box is an ‘off the shelf’ part that we can offer from our own mould, made to take a standard sheave. It is half the weight and stronger than a steel box. Exit holes can be drilled at either or both ends and different pin sizes are possible. This is an experimental installation in...Read More
