      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.

    Holeefuck. Incredibly impressive. More aerospace than marine.
  3. Club racer electronics

    FWIW...if you will be racing at night, instruments will be very valuable. If you need a good autopilot for shorthanded racing, instruments will be valuable. If day racing, then time and energy is better spent elsewhere.

    I'm fond of this one: http://app.nobeltec.com/
  5. Nowhere to Hide

    Yes, Governments have been able to track Class A AIS from satellites for a while now, and my understanding is also Class B provided the transmission is good. OCEAN-SCAN is clearly something new. You have a choice to be seen until 2019, then you won't. Will be interesting to see if it leads to more boardings. I'd guess authorities would be more interested in fishing boats than pleasure craft. I hope they will be able to tell the difference.
  6. Nowhere to Hide

    In case you want to, fuggetaboudit. This crossed my desk this morning. Inevitable, I guess. https://www.digitallook.com/news/aim-bulletin/srt-marine-to-launch-global-satellite-system-called-ocean-scan--2875929.html Emphasis added. 100% situational awareness, for the good guys only I assume. Now some random government can see me in the S. Pacific or wherever. Looking forward to those visits. I wonder how they will limit access to data. Or will Rocket Man be able to access data to show him every little fishing boat - or Navy Vessel - off South Korea? Or the US as long as he pays his bill? Probably already hacked by China, Russia, and Iran. What could go wrong? ________________________________________________________________________ SRT Marine Systems plc, the provider of maritime tracking, management and surveillance technologies, products and integrated system solutions for ports, waterways, fisheries and coast guards, announces that it will build and launch its own maritime monitoring satellite constellation, called OCEAN-SCAN, which will provide enhanced global vessel detection and tracking and a new recurring revenue source from maritime domain awareness (MDA) system project customers. The OCEAN-SCAN system will initially comprise six low earth orbiting (LEO) satellites, operating in a combination of equatorial and polar orbits to provide global coverage, but with enhanced coverage of the equatorial and border regions due to the location of most current MDA system project opportunities. It is expected that additional satellites will be added in the future. OCEAN-SCAN is expected to be fully operational in 2019. The satellites will enable SRT to sell long range vessel detection and tracking data to SRT MDA system customers and generate recurring revenue for SRT. Innovations in the satellite industry over the last decade have resulted in the development of small, low cost single purpose satellite system solutions which provide a proven and low cost turn-key platform into which sensor systems can be integrated. One of the leaders in this field is Clyde Space in Edinburgh and the Company has entered an initial agreement with Clyde Space who have a proven micro-satellite platform solution that is ideal for this application and can be utilised to quickly, reliably and cost effectively deliver the OCEAN-SCAN system within the required timescale. The OCEAN-SCAN system will host a combination of sensor technologies, including Automatic Identification System (AIS), to enable accurate and reliable tracking of all types and sizes of vessels, with or without an identification transceiver. This fusion of multiple sensor technologies on individual satellites is not found in the same combination on existing systems and will enable accurate real time detection of illegal maritime activity as well as long range reliable tracking of even the smallest fishing boat. OCEAN-SCAN will benefit from new technologies with greater capabilities along with system architecture innovations that enable the delivery of higher quality data directly into the customer’s existing SRT MDA monitoring system solution in real time. This will enable the seamless monitoring of vessels operating in maritime regions not covered by their terrestrial sensor systems. Simon Tucker, CEO of SRT Marine Systems, commented: “This is a natural and major strategic initiative for SRT that will deliver significant benefits for authorities seeking to secure and manage their maritime domain, as well as a new and recurring revenue stream for SRT through the sale of data to our system project customers. OCEAN-SCAN is fully funded via forecasted trading cash flow and further supported by our new working capital facility. Subject to the usual risks associated with launching satellites, we expect OCEAN-SCAN to be fully operational before the end of 2019. The new technologies and innovative system architecture of the OCEAN-SCAN satellite system, combined with our SAT-Trak vessel transceiver technology, and GeoVS intelligent monitoring and analytics system will deliver an unmatched level of fully integrated vessel tracking, identification and management capability to our customers.”
  7. Is Big Boat racing an athletic sport?

    Rich Wilson, two-time Vendee Globe finisher once said, "It's hard to describe how physically demanding the IMOCA 60's are." When I walk down the dock after singlehanding my Open 50, I know what he means.
  8. For what it's worth, Google trends search data on the term "sailing" from 2004, for US and Worldwide. Pretty dramatic decline over the last 13 years.

  10. Asymmetric off spin pole?

    If it were my boat, I'd do this: http://trogear.com/ I don't want lines running everywhere.
  11. Did you used to have a Tartan 10? Umm, yeeaah...
  12. Open 50 Rule general purpose centrifugal pumps. I have 4, one for each tank. A scoop feeds two pumps individually switched depending on which tank I want to fill. Pretty cool actually: "Oh, I'm starting to heel a little too much, let me push this button." Feels like I'm driving a Mercedes or something.
  13. Hi Roleur, Solo is right about PHRF suffocating innovation - will never pay. BUT, water ballast is the bees knees. When the breeze come up, I just pump up the windward tank to maintain heel angle. It comes up more, I pump up the aft windward tank. Boat settles down and trucks upwind through any chop. Feels luxurious, especially as I age! Only then do I start reefing. Same for reaching angles as well. While I haven't been out in a gale or storm yet, I assume the boat would settle down considerably if I fill all the tanks. My boat has a really nice 3 scoop setup that works well. Two 2" scoops aft feeding large pumps, cross-connected so the leeward scoop/pump feeds the windward tank. That way the scoop is always drawing. My tanks are port-starboard connected through 4" gate valves manually operated. To tack, open the windward and leeward sides & let the water flow to leeward, then close the gate valves. Mine are the same as are on Comanche, apparently. Sight tubes on the tanks tell you when full or empty. I've short tacked through a harbor with this setup as the water transfers in maybe 60 seconds. 2" vent hoses, one on each tank on the deck, tied aft onto the lower lifelines. Only downside is the water "spits" out the windward side vent, but I'll set up a baffle to settle that. The 3rd scoop is a little larger at 3", a bit aft of the keel. This scoop is larger as it can fill the tanks to leeward using water pressure, and I spin the opening around aft to dump the tanks. While my scoops were custom made of stainless, the link Leo provided is the standard that I think all the boats are using. So while I won't win any races on corrected, I cruise around fast and comfortably, loving the ride.
  14. AIS: Class A or Class B?

    It would appear the Vendee Globe allows Class B AIS units. From the 2016 Vendee Globe OSR Cat 0 Exemptions, NOR Appendix 8: OSR 3.29.12) is amended as follows : A class B AIS transponder is authorised subject to the following elements : - The antenna must be on the masthead. - The installation of the AIS must be checked by an organisation that is recognised for its expertise in the installation of this type of equipment (certified organisation or an approved installer). This organisation shall check : - The cable and the antenna must have the same impedance - The TOSS must not be lower than 40% - These elements must be certified for compliance by this organisation - The certificate of installation compliance dating no further back than one year must be submitted to the chief measurer in order to obtain the IMOCA Certificate. They also require a VHF Radio masthead antenna. Therefore any Class B installation would require a splitter, something I'm not comfortable with.
  15. Carbon vs alloy rudder post?

    I learned the hard way about the risks of home-brew carbon rudders: Zimaz Then there is the story of Uncontrollable Urge. With Aluminum or stainless, you know what you have. The strength is known and understood. With a laminate, you don't really know unless you test to failure and then you don't have the part. If the layup isn't perfectly uniform, progressive failure can occur as one or a few fibers take the load first & they keep snapping until total failure.
