I thought I might have missed a standard definition of where to measure deadrise. ITTC Dictionary Of Hydrodynamics provides two options on p 27:...
The "no-slip" condition applies at the surface, not away from the surface. The velocity is non-zero any small (or large distance) away from the...
Your assumption is completely wrong. Boundary layers have been the subject of very extensive research since the early century, and that research...
What rule or rules does this definition originate from? For smaller motorboats deadrise is frequently specified as the "deadrise at transom".
Probably the primary reason for many production boats. In the 1960's boats designed for racing started having reverse slope transom. My...
What is protected depends on the claims made in the patent. Coverage can range from a specific geometry, such as a specific sweep angle for a fan...
Another large schooner project is the 1885 Coronet, which is being moved to Mystic Seaport to complete its restoration. Mystic Seaport Museum and...
I assume this is the replica built in 1967, at the Goudy & Steyens Shipyard in East Boothbay, Me., for Rudy Schaefer of the F. & M. Schaefer...
Actually is done all the time, for example in machinery design. The formulas taught in high school don't apply, but the classical laws of...
Actually it is entirely possible to transform between frames of reference with the systems rotating and accelerating relative to each other. The...
GFCI works on current, not voltage, difference between the two sides of the circuit. If the current is the same (zero difference) then there is no...
Given the efficiency of available solid state inverters matching the voltage of the cable to the control system probably is not a major consideration.
Interesting question. Higher voltage means the conductor diameter can be smaller, but the insulation thickness increases. Presumably there is an...
Strip planking using a light wood such as cedar covered with cold molded wood can result in a lightweight hull. It's a method used by some...
Leo Lazauskas and E. O. Tuck published several papers on the drag of multi-hulls using thin ship theory. Leo formerly was an active participant...
A wider hull aft can reduce "squatting" at higher speeds. To minimize drag at lower speeds the immersed transom area needs to be minimized. Many...
There are two different "area rules" for drag reduction which appear to have been confused, and there effect on aircraft misunderstood. The...
Some canoes do not have seats, and are paddled while kneeling. Some canoeists kneel while paddling even when the canoe has seats. While not...
A catamaran will frequently have more air draft than a monohull of similar size and capacity due the need to have sufficient clearance under the...
Have a look at the 8.5m design in this free to download publication from FAO: Fishing boat designs: 2. V-bottom boats of planked and plywood...
