      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

Mayflower Autonomous Research Ship to cross Atlantic without a crew

If you should encounter a crewless ship out on the Atlantic Ocean in a few years, dont worry about it being the ghostly Flying Dutchman it may be the Mayflower, however. No, not the square-rigger that brought Pilgrims to America, but the Mayflower Autonomous Research Ship (MARS). Plans call for the wind- and solar-powered trimaran to sail itself from Plymouth, England to Plymouth, Massachusetts in 2020 the 400th anniversary of the original ships journey carrying out a variety of research projects along the way.

 

Using either or both of its two sails, MARS will be able to move at a speed of up to 20 knots (37 km/h or 23 mph) MARS will be 32.5 meters long and 16.8 meters across (106.6 x 55.1 ft), with a glass/aramid/foam composite hull and a carbon composite deck.

The ship is the focus of Project MARS, a collaborative effort involving Plymouth University, autonomous craft specialist MSubs and yacht manufacturer Shuttleworth Design.

 

It will be 32.5 meters long and 16.8 meters across (106.6 x 55.1 ft), with a glass/aramid/foam composite hull and a carbon composite deck. Using either or both of its two sails, MARS will be able to move at a speed of up to 20 knots (37 km/h or 23 mph). On less breezy days when the sails are automatically stowed belowdeck, its solar-powered electric motor will still take it up to 12.5 knots (23 km/h or 14 mph). The solar cells should be able to generate enough current that if traveling at 5 knots (9 km/h or 6 mph) under motor power, the ships range will be unlimited. Some of those cells will be on a folding wing, that will only open under calm sea conditions.

 

Navigation will be via a combination of GPS, and onboard collision-avoidance systems.

 

According to MSubs Brett Phaneuf, the crossing could conceivably be completed in 7 to 10 days, although it may end up lasting several months depending on what tasks MARS is put to along the way. Areas of research that it will be conducting include meteorology, oceanography and climatology.

 

"It is intended to house one or more modular payload bays, much like a Space Shuttle, into which a diverse range of mission equipment will be fitted to support the various research tasks," he tells us. "Equally important, we will be conducting research on renewable energy and propulsion systems for marine vessels, research on the software for automated and autonomous operations for extended duration, advanced satellite communications, and cooperative behaviour between nested automated and autonomous vehicles operating below, on and above the water simultaneously."

John and Orion Shuttleworth state:

 

"Our approach to developing the concept was to fully explore and take advantage of the opportunities that arise from not having to carry crew, and to create a vessel that is capable of using only renewable energy. Working within the limitations of renewable energy sources has given a clear direction to the developing form of the vessel. The solar cell area required for effective motoring is too large for efficient sailing and safety in large waves. To overcome this we are developing a folding wing system to increase the solar cell area by 40% in calm conditions.

 

"A trimaran was chosen because it provides the most efficient hull form for low speed motoring. The hull configuration developed from a requirement to reduce windage, while keeping the solar array sufficiently high above the water to reduce wave impact. Without the need for accommodation, the centre hull has been kept low to the water and the wings and deck are separated and raised above on struts. This also allows waves to break through the vessel and significantly reduces roll induced by wave impact. The outer hulls are designed to skim the water reducing resistance by 8%.

 

"The two masted soft sail rig, which will enable a top speed of around 20 knots, is designed to work with both or either sails hoisted, giving three sail combinations for varying wind speeds. Each sail is simply controlled by a single sheet, and the sails can stow into the deck taking up minimal space. Stowing the sails while motoring reduces windage and eliminates shadows cast over the solar cells on the deck, while allowing the masts to stay standing to carry navigation lights."

A pioneering project has been launched to design, build and sail the world’s first full-sized, fully autonomous unmanned ship across the Atlantic Ocean.

 

The Mayflower Autonomous Research Ship, codenamed MARS, will be powered by state-of-the-art renewable energy technology, and will carry a variety of drones through which it will conduct a variety of experiments during the crossing.
