We ended up with a B&G system on our J/109, mainly because most of it was already there when we got the boat.

Given that, I thought it would be a good idea to use the B&G App on our iPad, which we use to supplement the plotter.

What a mistake that was:

• No manual
• Constant hangups
• Clunky synchronization of routes with the plotter
• Terrible and counterintuitive interface
• Dangerous autorouting function

I just canceled my subscription, thankfully before the two-week trial ran out.

Back to TZ iBoat, which is, in my view, the gold standard for tablet navigation software.

Hopefully B&G will get their app sorted out, since I would love to have a tablet app that synchronized routes with the plotter, but B&G have a long, long, long way to go to catch up with TZ iBoat or to even be a safe and functional app, in my view.

I have used a bunch of iPad navigation software over the years, but TZ iBoat, by the same folks who have been doing navigation software on computers for some 30 years, is by far the best.

Lots of reasons, but the most important is that it’s the only app that I can enter and edit a route on without being driven to distraction. No, not as easy as a computer with a mouse, but way better than a plotter.

Anyway, TZ iBoat has just been upgraded with three new features, two useful, and one that should be avoided like the plague:

• Autopilot Output: TZ iBoat is now able to send information to your Autopilot (NMEA0183 sentences via TCP) when a route is activated. Make sure to check out their user guide for more information under the “Help” section.
  • We definitely don’t want to go near this one
• Bluetooth Mouse support: Many of our power users on iPad wanted a way to control TZ iBoat with a mouse. This is now possible.
  • This is a wonderful upgrade. A finger is just too blunt an instrument for entering waypoints and routes, and a mouse (or track ball) is best.
• Instruments Damping and Offset: TZ iBoat offers new settings to offset and damp instruments (course, speed, wind…). Speed damping can be especially useful in some cases to stabilize the Estimated Time of Arrival (ETA).
  • Probably useful, depending on setup.

We just updated our 11 tips to make navigating with a tablet easier and safer chapter based on our experience of doing just that on our new-to-us J/109.

While I’m not a fan of relying on tablets exclusively for navigation, on smaller boats like our new-to-us J/109 they can be a good option, at least in conjunction with a plotter.

However, the big problem can be how to charge a tablet and still keep it waterproof. The product pictured above solves that problem.

I’m planning to order one for next season.

I don’t care how much butchery it takes, we are having a plotter/radar at the forward end of the cockpit where it belongs, to supplement and backup the iPad we use for navigation.

The plotter below-decks is useless when shorthanded and we don’t like plotters on the binnacle, either.

The new on-deck plotter will act as an autopilot control head as well as show strategic information like laylines, should I have a rush of blood to the head and go racing.

The new plotter is much smaller than I would like, but compromises are required on any boat, and the smaller the boat gets, the bigger the compromises.

More on making the most of these small-boat navigation compromises.

Mock-up of the fascia that I just made to assist the composite technician who is going to fix my butchery and make it look nice.

Yes, I could do the glasswork, but it would take me three times as long and look half as nice—know your limitations.
