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")

How do use the Latitude and Longitude Plotting Interpolator?
bplipschitz posted a topic in Cruising Anarchy
So, looking at the chart that I just posted on my wall of my most recent bareboat charter, I see it has a "latitude and longitude plotting interpolator". I've never used this, never came up in any navigation instruction, and google is providing little, unless you want to get into MatLab (not a MatLab guy). We're talking paper charts, here, and I realize we're laying out some spherical on a 2D flat rectangular surface. How would one use this? Would you need to? Thanks. -
Need your help: crowdfunding campaign for a rugged tablet dedicated to sailors
BuenaOnda posted a topic in Gear Anarchy
Hi Guys! Being active in sports marketing and communication, I found myself completely at a standstill right from the start of this crisis. Not wanting to remain inactive, I gave a real boost to a project that had been in the corner of my head for a long time, a durable and waterproof digital tablet, dedicated to pleasure boating. A sailing enthusiast myself, I had been snooping around during my business trips to China looking for equipment that could help me in my hobby - in particular a waterproof tablet for cartography and navigation. For 3 years, I scoured trade shows, visited factories and brought back samples. I also went around discussion groups and the main French and English speaking forums to draw up specifications, like here on Sailing Anarchy : The main axes of which were: a screen that is REALLY readable in full sunlight, can be used with gloves and in case of water splashes, a very high capacity battery, a very accurate GPS chip, a waterproof and solid case. Today, the product is almost ready for production and I launched a crowdfunding campaign here : https://www.kickstarter.com/projects/sailproof/sailproof-the-sailors-rugged-tablet Ok, perhaps you'll say this is advertising, I won't blame you for that. But you have to know that, even if I succeed in my campaign, it won't pay for all the hours and costs I have had till today. My only goal is to launch the production a first batch of tablets. So, please, be indulgent with me :-) Thanks for reading me. JM -
Hi All, I've made this video to make sailors aware of the issues with modern, digital navigation. The sail training organisations promote traditional navigation, and nobody is really teaching the use of gps. Most navigation accidents are due to failure to navigate, but it's important to understand the possibility of chart errors, and the need for multiple devices. Traditional navigation is a good basis, but most of use only use gps now. Are we just getting lazy, or is the modern way safer?

The Polynesians located every habitable island in the Pacific Ocean about 1,000 years before the Europeans .. They had no charts and no writing but their methods have survived until this day. Ku Holo Mau On March 5th, 2007, Hokule'a and Alingano Maisu - two Hawaiian double hull voyaging canoes - departed Chuuk in the Federated States of Micronesia for the tiny island of Satawal - to honor Mau Piailug, our mentor in the art of non-instrument navigation. On Satawal, five Hawaiian navigators and eleven from Satawal, will be initited by Mau into the rank of Pwo - master navigator. http://www.samlow.com/sail-nav/satawal2007.htm

Ran across an article on the continued march of Magnetic North towards Siberia. https://www.macleans.ca/society/science/say-goodbye-canada-the-north-pole-is-moving-to-russia/ Aside from the obvious issues with navigation are there other effects? Looking at the chart that indicates the rate at which the change is advancing it struck me that it seems to somewhat follow the rate of climate change that is occurring. I don’t see a lot of conversation or scientific discussion on the relationship as compared to other causes. Since the magnetic field controls the ionosphere and the ionosphere has an impact on the atmosphere it seems to beg the question of what is the effect? To my simplistic, engineering based mind it seems a lot more likely to have a much bigger impact on climate than some minor trace gas that represents a tiny proportion of the whole atmosphere.
