      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.

Unmanned Trimaran Smart Enough to Trim Its own Sails

NOVEMBER 22, 2008

The HWT X-1, an unmanned sailingvessel prototype designed and built byHarbor Wing Technologies, Seattle (harborwingtech.com), could someday patrol ocean waters to protect marine areas, monitor the ocean and atmosphere, and augment U.S. military forces. The 30-ft prototype is currently being tested in the waters of the Papahanaumokuakea Marine National Monument, a 140,000-sqmile area in the northwestern Hawaiian Islands.

 

The brains of the boat is the SeaKeeper 1000 control system from SeaKeeper, a French company specializing in marine technology. It lets operators control the boat by VHF radio, satellite, or line-of-sight UHF communication. It also controls the sails and small electrically driven propellers, reducing power to the propellers when the wing-sail takes over most of the load. When speeds exceed 4 knots, the motors switch off and propellers fold away. Operators need only set patrol parameters or a destination and the SeaKeeper handles navigation. It can maintain a course to within 1 m in closed or harbored waters and to within 2 m in the open ocean.

 

A portable workstation-based command console uses a graphicuser interface to show operators navigational and situational information.

 

The production craft will measure 50 ft long, have a 40-ft beam, and a 60-ft mast. Draft is 10 ft with the hydrofoils lowered. Its airfoil will have 700 ft.2 of surface area. It will carry up to 1,500 lb of payload in 600 ft3 of storage space. Top speed is at least 25 knots and range is 500 miles. It will be able to spend three months at sea..

Unmanned Trimaran

On February 17th, 2009 Dave R (not verified) says:The Regulations relating to Prevention of Collisions at Sea require all vessels to keep a lookout at all times.

 

Even with radar, sonar, real time video camera etc, I do not see how an unmanned vessel travelling at up to 25 knots could fully comply with this requirement.

 

As an ocean-crossing yachtsman, (Yes, with enough crew to ensure that there is someone awake in the cockpit at all times) the thought of one of these vessels in my part of the ocean is a bit worrying....

Harbor Wing has now completed the initial design for the production level prototype of our open ocean Trimaran vessel, the HWT X-3. It will incorporate technology proven by rigorous testing of our HWT X-1 prototype. This vessel will integrate our highly developed unmanned guidance and control systems, sophisticated long range communications and powerful radar and telemetry capabilities with the robust tri-hull design."

thats pretty cool. I wouldn't worry too much about it being unmanned. I am willing to bet that it has a fail safe that if it loses contact it goes into irons kinda like how the unmanned drones will land or return on a preplanned route if they lose contact.
