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.

Catamaran Sailing Very Fast

The sailboats are the computer?
The Internet2 is currently faster than sailboats, and commercial Internet providers are upgrading their networks to handle today's and tomorrow's data as fast as customers and investors are willing to pay.
The current verified record for transferring bulk data over a very long distance (Tokyo -> Pacific -> US -> Atlantic -> Amsterdam) is about 8.8 gigabits per second (search: Internet2 “land speed record”), which could transfer a marketing petabyte in 909090 seconds or about 10.5 days. A plane full of tapes is still faster, but sailboats can't even come close.
If someone builds a terabit per second network across the Pacific (search: “Trans-Pacific Express”), and fully dedicates the bandwidth to the transfer of a petabyte of data, it would take 8000 seconds, or a little over two hours, at an initial cost of about $500 million for a new cable and computing and storage equipment on each end.
When I think of fast sailboats, I somehow think of Larry Ellison. While he may never have the technology to build a wind-blown sailboat this fast, he has the financial means to buy a company that has a boat that will install a fast cable for him, or at least lease an 10Gbps wave off of and installed cable for far less.
