Can you capsize a keelboat?
Unlike a dinghy, a keelboat won’t capsize. In a strong wind, it may heel a long way over, but the ballast in its keel is designed to keep it from capsizing. In a dinghy, to resist heeling you would use live ballast – the crew sitting out on the edge of the boat to counter the effect of the wind.
Why is it called a keelboat?

Why do sailboats not tip?
The primary reason sailboats tip over is that there is too much pressure on the sails for the ballast to counteract. This pressure is the wind. The stronger the wind, the more pressure on the sails, and that means more force trying to push the sailboat over.
Why does a sailboat not tip over?
So what really happens is – the wind tips the boat over a bit, this shifts the keel weight off centerline a bit. The boat will continue to heel over until the tipping moment by the wind is equal to the moment from the keel being off center.

How did old ships sail without wind?
For ancient square rigged ships what limited their ability to sail against the wind was not their sails, it was the lack of keel. Square rigged ships were less efficient and took longer to configure for different points of sail, but with a keel they could do it..
Can a sailboat go faster than the wind?
Yes, although it sounds implausible. With the wind blowing from behind and sails perpendicular to the wind, a boat accelerates. The wind speed on the sail is the difference between the vessel’s forward speed and that of the wind. Once the boat reaches the same speed as the wind it’s impossible to go any faster.
What is the purpose of a keel on a boat?
Beginner Sailing. The keel is basically a flat blade sticking down into the water from a sailboat’s bottom. It has two functions: it prevents the boat from being blown sideways by the wind, and it holds the ballast that keeps the boat right-side up.
