    C-Map: SDMicro <-> PC ?

    Since I'm moving to a new area, new charts are in order. With a Zeus 2 MFD as the primary display connecting to an H5000 Autopilot, getting something that plays nicely for the thin waters of the ICW and coastal areas is important to enable semi-automagic piloting on deliveries, allowing better lookout vs hand steering for 10 hours in a channel. Current state of Navigation/Piloting: Bought the Waterways guide for "flip chart" hard copy and will buy BSB/NOAA Raster for overview. Subscribed to the Waterways emails on updates (NOTAM) on missing ATON, Silting etc Downloaded the ENC's Expedition (runs on a Laptop below deck) INavX for IOS devices as backup Bought the C-Map N+ "REVEAL" card for the region for primary charts to display on Zeus 2 on deck Will record "sidescan sonar" tracks to upload into the "C-Map Social" maps (used to be called Genesis) Questions: Is there a means to do the planning/auto-routing off boat and export GPX to load to Zeus2? (similar to Active Capn) Back in the day, I thought I had a card reader for C-MAP cards of larger format, not finding one for the SD-Micro, is there one ? IOS App can do the routing, but not finding anywhere to export route, am I missing something? Happy to do routing on PC (MacOs) C-Map web app if there's a way to export ? I can use Expedition to create a route manually, somewhat tedious for ICW waypoints, do I need to buy the C-Map charts again (4D format ?) or is there a means to download from chart card purchase? The Social Map uploads are supposed to happen automatically with Wifi connectivity presumably every time we remember to record, they will update from dockside, is downloading of update automatic, or needs to be done manually ? With changing depths due to silting/dredging, given access to high resolution bathymetry (C-MAP Reveal, social maps and personal sonar tracks) what's the best means to exploit shallow draft ? Concept is to follow a minimum depth contour for least distance routing, using forward scan sonar to look for obstructions (and I am familiar with range in thin waters) Will the auto routing programs compensate for state of tide? (We have a ~ 4' tide range, and I only draw 4'3")
  2. Sounds like jealousy for the most part. You want “woke” go live it, don’t mind the urban dysfunction that it spawns.
  3. Well, I am trying to recall any regatta's or races of prominence in NC, and so far am not able to do so. Its sort of sail-by country, where you leave the Chesapeake and next Stop is Charleston. Pamlico and Abermarle are rather thin, Cape Fear and Hatteras are rather nasty in storms, and what's left ? As for slagging the drive, I-95 is nobody's idea of a scenic route. We went North to Maine on it last week, and in NJ, to avoid the GW, took the Palisades up to Tappan Zee, coming south went 84 out to 81 and drove the Susquehanna and Shenandoah Valleys through PA/MD/WV and into Front Royal and eventually back to 95 to get through NC as fast a possible.
  4. This from someone who lives in NC. Seems to be jealousy operating.

    What would you do with extreme compass accuracy?

    if you can get a two sensor GPS that for example mounts on bow and stern pulpits, it should be able to measure/derive: Position (at 10-20 Hz update) Position_Bow lat/lon/Alt Position_Stern Lat/lon/alt Position_Center_of _Rotation SOG SOG_Bow SOG_Stern SOG_mean/CoR COG COG_Bow COG_Stern COG_CoR Heave & Pitch Heading from Bow & stern positions std deviation of heading (helm fatigue/noise in flat water, error band in seas) Speed at center of rotation along heading (analogous to BSP) Speed at center perpendicular to heading (Analogous to leeway) Rate of turn Bow and Stern and derive center of rotation Radius of turn at bow/stern None of that will give you heel and roll, but those can be from inertial sensors rather than satellite With better heading/pitch and heel/roll input to Radar/sonar you should get better imagery and cleaner Dopplers/ghosts With better pitch/heading/roll the autopilot and TWA/TWS calculations should be better still, allowing more critical tuning & analysis of steering

    Building A Sail Pack

    sailmaker got me solid round batten stock, worked better https://bainbridgeintusa.com/wp-content/uploads/2016/04/bi_sailmaking_hardware_catalog.pdf

    PVC pipe in smaller diameters is not strong enough. (3/4” 17’)

    Sailpack + Dutchman Anarchy

    Sailrite has kits.... Made Main and Mizzen covers for Lioness, zipper panel for the front of mast, and two side panels that are zipped between lazy jacks for each sail. Pro Tips: Get some round batten stock from your local sail maker to hold the top stiffly in a hand sewn pocket. Run a recirculating line from a block on topping lift to forward end to pull the zipper both ways. Full battens make it easier

    Anarchy V autopilot

    A question that may or may not be relevant is does the autopilot need to handle the boat when Scooter is injured and can't hand steer?

    Soundbar Anarchy

    What's your use? making program voices audible ? Making movies, concerts and sports more enjoyable with better fidelity, and bass response? Making 4K Movies with advanced multi channel sound tracks more Theater Like? I have two Sony's and they play well with the Sony Bravia TV's. Generic integration may be adequate for your uses, but same brand systems have some ease of use "wife friendly" value Advanced features such as Dolby Atmos to give Overhead sound, and streaming music from Pandora/Itunes etc are nice...

    Where to move?

    That's on the Alameda side.... My experiences so far in Dixie are that time is a sort of elastic "manana/Island time" concept, and that some folks are prompt, a few run early, and many run late, but they do get there, and being in a hurry is not a useful attitude. Had a Refrigerator repair tech show at 8 pm, and he had two more stops...

    Showtime capsize on return trip

    Well Golly Jack if we only built 10 carriers a year, but we have not since 1945 or so. Agreed the EU doesn't need carriers, though the UK has found them useful (With US F-35...) and the French seem to want to play the global power game, albeit not so successfully the last 200 yrs or so, and not so successfully with French weapon systems, which have some excellent counter examples to their current standard of 2nd tier. An EU military would probably be even worse than the UN peacekeeping forces, as each country tried to steer the procurement to their suppliers, and the language and cultural barriers further diminished coordination. Ask yourself what does the EU provide that's worth One billion? Standardization of market specifications to reduce transaction costs? Or the simple belief that a few thousand years of slogging land warfare based on religion, family squabbles and disrespect can be put behind if only there's a sclerotic bureaucracy to provide an alternative? Call yourself that if you feel it apropos, even Woodrow Wilson's America came to protect you, and then you guys bungled the peace so badly that Roosevelt's America had to do it again, a generation later. Stationing troops and equipment to forestall the spread of Communism seemed to make sense, though arguably now that you guys collectively are choosing to do business with the Russians on a key energy supply, since your Green initiatives are not panning out that well there's much less to protect. Russia's over, just a cold version of Pakistan.
