  1. Well, the light sticks won't do for meeting USCG requirements. The new USCG requirement is referenced here RTCM standard 13200.0 https://www.sailmagazine.com/virtual-boat-show/sirius-signal The old standard is here: https://www.ecfr.gov/current/title-46/chapter-I/subchapter-Q/part-161/subpart-161.013
  2. We use CBx and Px, where x starts at 1, for the start line, on Zeus3, go back to an existing route, choose mark to insert , click bulk insert, type in CBx.
  3. The SCX20 and a well calibrated paddlewheel will help with the laylines, etc.
  4. Blue published formula?
  5. Anyone have success interfacing this to NMEA-2000 MFD's like Zeus 3, using Calypso provided interface? https://calypsoinstruments.com/
  6. I went through this in June. The problem was the cable in the mast. Rather than flat out zero, I got 0.5 knots (maybe a function of how the H5000 works?), first for short periods of time, and then over a few weeks the 0.5 knots value started occuring for long spans of time.
  7. I have 18 auto/cigarette style 12v sockets on my 36 foot race boat including a cluster for crew to bring aboard inserts for smartphone chargers from their car, and a variety of cables to cover anyone that did not. They are also used for three mobile 12v fans used by crew that overnight aboard, mobile boom boxes, laptops, charging handheld vhf, cpap machines, and more. Hair dryers and other items that don't work on 12v, have no hope on my boats limited 160Ahr battery capacity, so this arrangement works perfect. I have a dedicated 25Ahr breaker to shut down these parasitic loads, and a few blue
  8. You are looking for course over ground or heading?
  9. I am thinking of getting one of these new electronic two color visual distress beacons, have read the practical sailor magazine article, and had the oppotunity to speak with Drew while he was writing it. Can anyone poke holes in this logic below for recreational sailboats, racing or cruising, vessels only (excluding man over board)? It would appear chemical flares (handheld and parachute), for boats within range of Rescue 21 (20 nm), have been entirely obsoleted when vessels are equipped with Rescue 21 enabled ship DSC and handheld DSC radios. With those, chemical flares isn't the m
  10. Cannot match a parachute flare, true, but in regards to the handheld flares, it is debatable which is better.
  11. Nope, this is a new generation of product. New = 2021, the Sirius C-1002 is only available over the last couple of months.
  12. Check your practical sailor magazine for this great article on electronic flares, and specifics on how those based on latest USCG standards (two LED colors, etc.) are a worthy replacement for chemical flares. https://www.practical-sailor.com/safety-seamanship/distress/distress-flares-go-electric Old electonic design = major negatives, must be kept very level to the ground, or they are unviewable in all directions (not easy to accomplish on a boat) and not easily recognizable as distress light from background lighting. New electonic design = many positives, read the article.
  13. I use them, I am not going back. * I had nearly new stainless fail on me, got me looking at other options * affordable to replace if in question * no measurements needed like stainless. * crew likes it when hiking out * always looks good I would do better next time. * find my old turnbuckles and use them, making them adjustable ahead of an one design inspection would be more convient than redoing knots.
