      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

Unmanned Trimaran Smart Enough to Trim Its own Sails

NOVEMBER 22, 2008

Edited by Stephen J. Mraz

 

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.
