Country specific advice | boating abroad | RYA
Saved by uncleflo on February 12th, 2022.
A vessel must comply with the regulations of its flag state wherever it is in the world. In addition when cruising the waters of another country (as explained on the page Law of the Sea and the Coastal State), that country can require you to comply with its national legislation (as applicable to foreign flagged vessels). The UK's relationship with the EU changed from 1 January 2021. As a result you now have an obligation to report to UK Border Force when moving into and out of the UK by recreational boat. You should expect greater scrutiny and requirements to report on arrival and departure, when moving between the UK and the EU and/or the Schengen area by recreational boat. For each of the countries listed, answers to questions that regularly come up are provided. The information applies to UK registered boats owned by private individuals who are resident in the UK, which are taken abroad by them on a short visit. If you choose to base your boat abroad, have both property and your boat in a country, become resident abroad, cruise a company-owned yacht or use your vessel commercially (including offering it for charter), the rules may differ considerably from those applicable to private vessels on short visits. Specialist advice should be sought from the authorities (or a lawyer) in the country concerned.

Entering the Harbour
Saved by uncleflo on January 17th, 2022.
To assist the safe passage of small craft to and from Portsmouth Harbour a Small Boat Channel for vessels less than 20m in length including Personal Watercraft (PWC) has been created on the western side of the harbour entrance. The 50 metre wide Small Boat Channel is shown on Admiralty charts 2625 and 2631. Its northern and southern extremities are at Ballast Pile (50 47.62N 001 06.83W) and No 4 Bar Buoy (50 46.97N 001 06.48W) respectively. Small boats are reminded that they can be difficult to see and the harbour entrance is a blind bend to larger vessels and traffic leaving the camber. Vessels approaching or departing the small boat channel to the south, should follow the line of the port lateral boys to avoid grounding on the South-East corner of Hamilton bank. The following vessels under 20m in length are authorised to use the main channel and loiter in the Small Boat Channel when their duties require; pilot boats, police launches, QHM Harbour Patrol launches, Border Force craft, Royal Naval vessels, lifeboats, senior officers’ boats flying official flags or discs and tugs engaged in towing operations or escorting a vessel. Small boats may continue to use the Small Boat Channel when the main channel is closed for the passage of a large vessel other than a Queen Elizabeth Class (QEC) Aircraft Carrier. The Small Boat Channel will be shut to all traffic during QEC transits.

How a Sail Gives Lift
Saved by uncleflo on April 10th, 2021.
How many times have you heard that a sail gives lift to drive a boat because, "the air travels faster on the lee side for it has farther to go than it does on the windward side. So the pressures are different and you get lift." Well, that is wrong! Even a perfectly flat thin airfoil, with the same distance on both sides, has lift when it is at an angle to the wind.

Arvel Gentry | North Sails
Saved by uncleflo on April 10th, 2021.
In the first edition of the Art and Science of Sails, written by Tom Whidden, president of North Sails Group, LLC, and Michael Levitt, and published by St. Martin’s Press, the authors used Arvel Gentry’s now famous Bathtub Experiment to demonstrate the existence of Circulation, or a second force, that operates around an airfoil, like a sail, wing, or keel etc. Big picture: it’s the combined effort of these two forces that makes the wind speed up on the leeward side — and thus show low pressure — and slow down on the windward side of a sail — high pressure. Gentry was the Boeing engineer who first taught sailors aerodynamics. These diagrams first appeared in Gentry’s Sail magazine articles. In the Revised Edition, the authors used computer testing to show where the wind speeds up around a sail plan and where it slows down. And why and by how much? Nevertheless, Gentry’s experiment is the standard — still popular on the web — and it was left it out of the Revised Edition with trepidation, but we linked in the book to this web page.

An Introduction to the Physics of Sailing | MIT BLOSSOMS
Saved by uncleflo on January 20th, 2021.
The goal of this lesson is to explain how sailboats work by exploring basic physics principles. At the end of this lesson, students will be able to identify the forces acting on a sailboat and explain how the combination of these forces results in the forward motion of a sailboat. Students should be familiar with vectors and be able to use them to represent forces and moments, and also should be familiar with using free body diagrams to represent forces and moments. A basic understanding of fluid flow and/or resistance might be helpful, but not necessary. This lesson and the follow-on assessment will each take about one hour to complete. Students only need pen/pencil and paper to complete the activities in the lesson, although an optional activity where students make their own sailboats would require additional materials. The classroom activity challenges are centered around small-group discussions based on the questions posed before each break. Free body diagrams, or another conceptual representation of his or her answer, should support each student’s solution to the questions posed in the video. Instructions for the option of having students design their own sailboats as part of this lesson can be found here: https://tryengineering.org/teacher/sail-away/

Surfboard Hull Design
Saved by uncleflo on September 14th, 2018.
I have been wondering about this a lot in Mini Simmons surfboard design (surfboard design in general)—what is a hull and how does it influence the board and the ride? Two factors are at work when a planing surfboard is in motion: the propulsion power, or force, that creates forward motion (the wave energy); the resistance that opposes it (your fat ass standing on the board). When at rest, a surfers weight is borne entirely by the buoyant force (also depending on how much beer you drank the night before). At low speeds every hull acts as a displacement hull, meaning that the buoyant force is mainly responsible for supporting the surfer. As speed increases, hydrodynamic lift increases as well. Ok, you got to reach back to some physics for this one.

Hydro Generator
Saved by uncleflo on September 14th, 2018.
The hydro generation or “creating energy while sailing” function is an automatic feature in all Oceanvolt motors. This feature is activated by pushing the button on the Oceanvolt displays for 5 seconds. The display will automatically switch to regeneration mode showing the current generated power, RPM and time until the batteries are fully charged. With a normal folding propeller the motor kicks the blades out and centrifugal force combined with the motor controller keep the blades open. The motor controllers tune the system actively at 10 Hz which prevents the blades from closing (too much braking would close the propellers). This is continuous monitoring, the system will adjust the propeller RPM depending on the boat speed.

How to force word wrap using CSS by Kasper Tidemann
Saved by uncleflo on March 28th, 2018.
On this blog, I have several code examples with a grey background like this: some fancy code. All the code examples are contained within <span> tags. But what if a span tag contains a word – say, a path to a file on a Linux server – that is longer than the width of the paragraph (the line width)? How can you force the text inside the span to word wrap? There’s a simple, very useful CSS trick you can use for this: word-wrap: break-word;.

Buzz Aldrin
Saved by uncleflo on September 2nd, 2014.
Selected by NASA in 1963 into the third group of astronauts, Aldrin was the first with a doctorate and became known as “Dr. Rendezvous.” The docking and rendezvous techniques he devised for spacecraft in Earth and lunar orbit became critical to the success of the Gemini and Apollo programs, and are still used today. He also pioneered underwater training techniques, as a substitute for zero gravity flights, to simulate spacewalking. In 1966 on the Gemini 12 orbital mission, Buzz performed the world’s first successful spacewalk, overcoming prior difficulties experienced by Americans and Russians during extra-vehicular activity (EVA), and setting a new EVA record of 5 ½ hours. On July 20, 1969, Buzz and Neil Armstrong made their historic Apollo 11 moonwalk, becoming the first two humans to set foot on another world. They spent 21 hours on the lunar surface and returned with 46 pounds of moon rocks.

Tutorial on back EMF suppresion: its causes and its cures.
Saved by uncleflo on July 17th, 2014.
Physical electronic access control, almost always, involves driving an electromagnetic locking device of some kind. It might be a powerful magnet or a smaller solenoid within a strike. All these devices are subject to the same basic laws of physics. The electromagnet will store energy when powered and will generate a “back EMF”, or counter EMF (CEMF), when the supply is switched off.

B-2 Stealth Bomber Crash Scene Photos: Exclusive First Look - Popular Mechanics
Saved by uncleflo on May 19th, 2012.
After taking you inside the Air Force's investigation into the crash of a B-2 stealth bomber, PopularMechanics.com has obtained the first still photos of the February accident—and they're pretty stunning. With last month's technical report detailing the demise of the Spirit of Kansas came footage from security cameras at Andersen Air Force base in Guam. Officials also snapped—but, until now, did not release—still photos of that crash site. In the pictures, firefighters work in silvery suits and crash teams cautiously approach the empty ejection seats, which use explosive charges to gain distance from a foundering airplane. Both pilots were able to eject safely through panels in the airplane's cockpit roof. The white spray seen in the photos is fire suppression foam.

U.S. Military Taught Officers: Use 'Hiroshima' Tactics for 'Total War' on Islam | Danger Room | Wired.com
Saved by uncleflo on May 13th, 2012.
The U.S. military taught its future leaders that a “total war” against the world’s 1.4 billion Muslims would be necessary to protect America from Islamic terrorists, according to documents obtained by Danger Room. Among the options considered for that conflict: using the lessons of “Hiroshima” to wipe out whole cities at once, targeting the “civilian population wherever necessary.” The course, first reported by Danger Room last month and held at the Defense Department’s Joint Forces Staff College, has since been canceled by the Pentagon brass. It’s only now, however, that the details of the class have come to light. Danger Room received hundreds of pages of course material and reference documents from a source familiar with the contents of the class.

As mentioned in other answers, the flash player is single threaded, if you don't break up your work into discrete chunks that can executed in separate "frames", you're going to see jumps and stutters in the ui, which is effectively what you're seeing. If you really must see that 12% message, then it's not enough to invalidate the display list, as the display list isn't getting a chance to update until after the 56% work has completed, you must explicitly interrupt the natural event cycle with a call to validateNow() after your message has been set.
