Another important part of the boat that is in the water is the propellor itself. For "The Laughing Cavalier" it
was decided that it needed enough performance to allow it to cope with tidal waterways and fast flowing rivers. With
the help of a company that specialises in matching propellors to hulls, the size of the propellor was determined together
with the power needed to drive it at the most efficient rpm. From this information we were able to determine the size
of hydraulic motor needed and this then gave us the engine power necessary to achieve the performance we required.
So now all of the components in the drive system are matched and operating at their best and give "The
Laughing Cavalier" a theoretical top speed of 6.8 knots which is more than enough for her to operate comfortably on
Lastly, "The Laughing Cavalier" has a modified rudder fitted. Horizontal fins are fitted
at the top and bottom which improve its performance. The effect is noticeable and the rudder is quite neutrally balanced.
