I do welcome the concept
of the electric motors, but have grown increasingly uncomfortable with the continuous emphasis on large battery capacity and recharging when sailing. To my mind all of this is achieveing three things that are really bad for the cruiser:
It makes the boat a lot heavier, when it should have been a lot lighter (battery weight).
It makes the electric system very complex.
battery capacity constrains the power output and causes significant problem when motoring for any distance.
To my simple mind, a hybrid system is much more simple and offers significant weight savings.
By hybrid, I mean the installation
of a purpose designed generator
, that is used for engine drive. It is then available for battery charge and running AC. A single generator
would be a simple installation
, and the battery weight savings would be substantial. You also avoid all that speed reduction by being able to use folding props.
As another idea for weight saving, has anybody investigated the use of titanium anchor
chain - A very quick look suggests that it is less susceptible to corrosion
, and strength to weight is much superior, hence possibility of reducing the weight - of course that would have a knock on effect of reducing the effectiveness of the anchor
