The ORCA Sailing Processor: (PART 2) A Deep Dive into True Wind Magic

Image
In my recent post about our ORCA setup , I promised a proper technical deep-dive into how this system actually works. Well, buckle up  (and this is coming sooner than I thought) – we're going down the rabbit hole of sailing physics, sensor fusion, and why getting accurate wind data is both harder and more important than most sailors realize. The "True Wind" Problem Here's the thing that tripped me up early in my career at Magellan GPS: calculating true wind sounds simple, right? You've got a wind sensor on your mast, you've got boat speed and heading – just do some vector math and you're done. Well, no. It's that 'devil in the details' thing. It turns out the wind sensor on your mast top is basically not telling you the truth. Not on purpose, but it's being influenced by so many physical phenomena that the "measured wind" it's reporting bears only a passing resemblance to the actual wind your sails are experiencing. And wh...

2025 Season Recap

Image
  Here’s a relative rarity for us, we actually managed to get team photos at the WYC banquet! A fun end to a challenging season. As our 2025 trophy frame states, this was ‘ the summer where we weathered storms and adjusted our sails ’ Due to medical issues and family things, we only ended up racing in about half the number of our typical WYC races. This made it almost impossible to do well in any series event, because in each major series we had races that we had to score as DNC (Did Not Come). In actual numbers, we showed up for 25, but due to light airs this summer we only finished in 12 that were raced! But it’s a show of our determination and capability that we won both of the single day regattas, the distance race Burton cup, and the windward/leeward Frostbite cup. And we ended up 3rd in the bitterly contested T-Series, while having to score a DNC! Jean asked if we actually had a trophy wall of pictures, and we sort of do. It’s not big enough for all of them so we just have 10...

2025 BlueJ picture showcase

As we do every year, here is a section of some of the better pictures we got of BlueJ; some we took, some from friends, some from strangers! Crossing with Cyclone BlueJ as art, by our PRO Chris Upwind in the Commodore Cup Jodi being Jodi! Code 0 reaching in the Commodore Cup Finishing! Rounding the windward mark Windward prep Coming in after an M-series abandonment due to ZERO wind. BlueJ on the hook GoPro view of a light air spinnaker reach. Kisses are for WINNERS '

Post-race analysis - 2025 Frostbite Cup

Image
I try at least once a year to present a detailed BlueJ race analysis, backed up with either pure analytics data and/or video. For 2025, I going to review of performance in the WYC Frostbite Cup with 360 video. Date October 25 2025 Race WYC Frostbite Cup Weather 50F,  cloudy / clear mix Wind 9-14 knots SSE   (130T)    FLEET - WYC PHRF 1 Spinnaker Crew: 4 Driver/tach, Main, Pit/Jib, Foredeck/Spin Video Tech: DJI OSMO 360 with DJI BT/GPS remote, DJI 'invisible' selfie stick Instrumentation Tech: Raymarine ST60+ Wind, Depth, Water Speed, ORCA Core sailing processor, ORCA Display 2 Mast Instrument, Sailmon MAX Start timer and lift/knock, Actisense NMEA2k/WiFi Gateway PRESTART: Wind pre-start looked even up the course, with no real line bias, We planned to go for a solid mid-line start, focusing on having room below. Competition wise, we have a J80 that can present problems, and a Santana 23TR and US-21 that are like rated and well sailed. And Impulse 26 that is much faste...

ORCA Instrumentation (Part 1)

Image
As many know, I'm a bit of an instrumentation geek when it comes to sailboat racing. This is particularly relevant on BlueJ, which is a bit of a unicorn racing in a USA PHRF handicap fleet. Without like-boats nearby to judge real-time performance, we end up relying on presented numbers based on boat performance to stay on pace. And this has led us to this: Our brand new, all-singing, all-dancing ORCA Core system, fully integrated into our existing NMEA-2000 network. And while not perfect, it has fundamentally changed how we sail and race BlueJ. But first some backstory. After years working at Magellan GPS where my team designed some of the first stand-alone marine plotters, I've alway focused on having detailed sailing data on the boat. For racing, this started with a TackTick Racemaster compass, which actually used a mechanical fluxgate compass! Next came the Velocitek ProStart, a Prism, a RaceGeek, a Sailmon MAX and then a stint at Vakaros where I ran global sales and marketi...

New 360 camera solution

Image
 If you scroll through my YouTube page, its clear that I've been a fan of recording our sailing using action cameras. This started with the original GoPro in it's clear plastic case, evolving through generations of later GoPros. Up next came pendulum-based horizon leveling mounts, ands then to optical correction. Later 360 cameras showed up, starting with a sketchy asian model I bought at Schiphol Airport on the way to Mobile World Congress, a Kodak VR360 off of eBay, and then finally to the GoPro MAX, which fixed the show-stopping problems associated with their first effort. I used the MAX quite happily for several years, but the the workflow associated with making videos with watching was almost unbearable for someone that did it for fun, and not profit. Getting the video off the camera took an hour, and then the editing was painful. So I was intrigued with both the Insta and DJI released 8Mpix 360 cameras, with glowing reports on ease of use. After some research, I found a s...

Making the switch to Lithium Batteries

Image
I've been thinking about switching from Lead-Acid batteries to Li-Ion for several years, but have been put off by the fact that I would have to change pretty much EVERY part of my charging and battery system. The benefits were very clear however, and I knew it was just matter of time. That 'time' came mid-season, when I noticed my group 29 110Ah Lead-Acid house battery was not holding a charge. Looking around locally, it was going to be about US$130 to replace. For LESS than that price, I could have 100Ah LiFePO4 battery (complete with an integrated Battery Monitoring System (BMS) delivered to my door. The benefits are real. Over 80Ah (close to 100 in a pinch) of useable capacity (vs 45Ah), at 1/3 the weight. And 10x the number of charging cycles, and faster charging. This would be a slam-dunk for any boat owner, if that was the end of the story. But it's not. The trick is the the BMS, a 'computer' built into the battery that manages its charging. One of th...
