Does a model boat have to have a keel and rudder?
For a project,I am designing a sailboat that will have to sail on water. And when I tested it,it acts the same with them as it does without. It goes just as fast. The only difference it is a little more stable.
I also need to know how to make a model sailboat more stable,even with a keel and rudder. The boat still turns like crazy and sometimes even flips and goes backward.
Please help.
The reason your sailboat is behaving the way it does is that there is more wind than it can handle. In other words it is just being blown around the water and not sailing. For a boat to truely sail ..ie go upwind,it needs some kind of counter balance and that is the function of the keel. The rudder will only work when the water is moving over it,so that it can actually deflect the water. These problems are very common for small models and it is very hard to get the scale right and make it sail too. Hope this helps.
