Bad Weather Problem...continued

On old Aries and many vane gears of today …….

When I took over the production of the Aries vane gear, I had a talk with Nick Franklin about his earlier models. The model to the right was produced for about 1 ½ year. Nick told me the story how he got many nice replies from customers but also the odd ones that had had very bad experiences where the Aries suddenly had lost control of the boat in bad weather. In harbours quite a few of the gears had damages done by bumping against poles or heavy lines getting caught on the gear.

The damages in harbour was quite simple, the construction was not perfect. Imagine that you hold a shaft in one hand, the shaft pointing aft. If something touches the shaft, you have little chance to hold it. If you hold it in one hand and with the other you hold the end sticking out, you are much stronger if something touches your shaft.

Weak construction

Strong construction

The bad weather problem was a mystery for a long time. Mr. Franklin had no idea what went wrong. Then one day the weather was very bad. Mr. Franklin sailed out into the Solent in his boat to see what happened. He tried all different courses and finally it happened: The mad movements of the boat + the waves pushed the servo rudder out of the water. Of course this would happen. It was simple law of physics!
