Anchoring: How much rope or chain should I let out? - NauticEd Sailing Blog
Saved by uncleflo on February 13th, 2022.
Anchoring, and getting it right is such an important topic that we thought we’d make this excerpt available for free in open space. Please enjoy how we dive into science and mathematics in these courses. If you like our style and how much knowledge you believe you could pick up in a full NauticEd course based on this little excerpt, consider take our full range of online sailing courses. Plus NauticEd has practical on-the-water training schools throughout the USA and Canada as well as other international locations. Check out, our two free sailing courses. NauticEd is a recognized sailing education body by the United States Coast Guard and can issue an official sailing license which is required by some countries to sail in their waters.

MIT OCW - 2.972 How a Hydrofoil Works
Saved by uncleflo on February 12th, 2022.
The rquirement is to lift the boat's hull outside the water. Hydrofoil (It is a foil or wing under water used to lift the boat's hull until it is totally outside the water.) Explanation: 1. At low speeds the hull (body of ship) sits in the water and the hydrofoils are totally submerged in the water. 2. As the boat's speed increases, the hydrofoils create lift. 3. At a certain speed, the lift produced by the hydrofoils equals the sum of of the boat and cargo weights. Therefore the hull comes out of the water. 4. Instead of having an increase in drag with increasing speed because the hull is lifted out of the water (contrary to what happens in traditional boats due to pressure drag), the hydrofoils provide a more efficient way of cruising. Decreasing the drag contributes to the better use of the power needed for the movement of the boat.

Which drogue should you buy? 7 drogues on test - Practical Boat Owner
Saved by uncleflo on April 10th, 2021.
When your boat’s being battered by a storm and you want to ride things out, a drogue will make things more comfortable. But which one should you buy? We tested 7 to find out... Of all the safety kit we’re told is essential to ensure our safety at sea, a drogue is fairly low on most people’s lists, especially if they only sail in sight of land or in coastal hops. But drogues have many uses aboard, and could help you ride out a storm, enter a harbour safely, steer after the loss of a rudder or keep you safe under tow. They could, then, save your boat and your life. With many models available, we put seven to the test.

The truth is that I did not come up with this concept on my own. I found the Lotus Sport 110 Bike while doing some searches and fell in love with the design. The Lotus Sport won a leg or two of the Tour De France before the UCI came out with its bike standards; which pretty much killed the bike. Anyway there are still a few around, here and there, but that doesn't matter because I decided to build one with my own "flare." I decided to label this design the Z Frame because it looks like a "Z" (when looking at it from the left side). Here is a photo of the Lotus Sport 110- Click on the photo to go to the forum where I got this picture, or if you want more information.
