self driving boats
Sunday was a beautiful day on the lake, my wife and I took a nice long trip over to Alton Bay, as I was cruising along enjoying the view, I started to think, would there ever be a day when there will be self driving boats, with all the hype with self driving autos, and how would they navigate the witches without a lighthouse ??

Totally self driving from leaving the dock to your destination is probably a ways off, but the reality is autopilot has been around for a while and with all of the technology out with GPS, radar, AIS, etc., we are already there in a lot of ways.

Probably better...
Than some of the "captains" out there on the average summer weekend. I saw a lot of strange stuff this summer.
Lot of big boats with small brained helmsman... Enjoying post-Labor Day! |
Big boat?
I'm not sure what a big boat is. In the 50's my family owned a 30' cruiser. A big boat for the day. Now, a 25' (common) deep vee will throw a bigger wake, never mind what a 20' wake boat will do. Categorizing is usually not a fair statement.
You want "self-driving"? Get rid of your ego and let your wife, or other passenger, take the helm. This macho thing that the man has to drive is just plain ridiculous. I hope when you have a heart attack, your wife or other passenger, can drive to the nearest dock and call for help on the VHF. If that isn't the case on your boat, I suggest you are not a qualified captain. Safety of crew and passengers first, Captain goes down with the ship. |
It will never happen.
After one weekend day on the job the computer would resign. |

Then you would just have a bunch of self-driving boats full of robots riding around the lake and clogging up the sandbars and we would be paying giant bills for it all as our self-driving boats and fun robots will be like our cable tv with its 1000 channels we never actually watch,,, Time to bring back analog boating, no bow thrusters with joysticks, no GPS, no drive by wire, just good old fashion clouds of 2-cycle oil, clothesline steering with all the pulleys, water skiing on plank skis behind an old Glastron with back to back "jumpseats" https://www.winnipesaukee.com/photop...t_Glastron.jpg |
Self-driving boats are a lot closer than self-driving cars (self-driving cars are still a LONG ways off).
An autopilot and programmed course can get you most of the way to "self driving boat" pretty easily. Radar-based collision avoidance (or warning) is also available. |

The self-driving cars are mostly OK today at dealing with what I would call "normal" conditions - well marked roads and signs, no adverse weather conditions, minimal amount of random incursions into their lane by pedestrians/animals/etc. BTW, I've been working with AI and video analytics applications using deep learning for more than a decade, including self-driving vehicle applications. Not only is the "learning" part not there yet, the various sensors used (lidar, optical or thermal imaging, short-range radar, etc.) all have enough short comings on their own that even if the software was perfect, the input data is far from reliable from the perspective of creating a truly hands-free self-driving car. Where are at the stage of highly assisted driving. That is unlikely to advance significantly in capabilities in the next decade. What we will more likely see is the current advanced technology seen in Tesla or Mercedes vehicles working its way down to average consumer vehicles. |
In 1933, a 37'10" sailing yacht w/ 7-feet draft, the Winnibelle II crossed the Atlantic from France to New York using an autopilot sailing system while sailed by one lone sailor.
You just set it, fo-get it, and go below to catch some sleep or whatever ...... if it worked good back in 1933 ..... then, it should work good in 2019 on Lake Winnipesaukee ...... the Winnibelle II in 1933! |
My boat came with auto-pilot and I thought it might be nice on occasion, until I started using it. WOW, it is awesome. I only use it to hold a heading (not to follow a route), but it dramatically improves the boating experience and reduces fatigue on long passages. I hardly touch my wheel at all now and use auto-pilot to steer 98% of the time. When I was transiting the Erie Canal earlier this year, I found it incredibly useful to maintain a perfectly straight course on the long straight sections of the canal. I also got very good at steering with incremental heading degree changes on the auto-pilot push buttons when I went through turns. I don't think I'd ever have a boat without it now.

I'm intrigued by auto-pilot on a consumer level boat. How does it adjust for chop? Obstacles? Or does it just adjust steering and the driver needs to be alert and adjust for those things? If the latter, I think I might become complacent from the break and lose track...

What I have found is that I can concentrate more on keeping watch as I am not making constant course corrections AND I don't get nearly as fatigued as I used to get on long passages. I think it has made me safer. This year, I did double digit five-hour to ten-hour passages (50 to 120 nautical miles each) on my "new" boat and that's something I would have never done in my old boat. That said, I routinely covered those distances in my old boat, but at three times the speed, so 1/3 the time and a lot less fatigue. I'm not sure I'd bother installing auto-pilot on a Winni boat unless I was using it to cross the length of the lake routinely at <11 knots. |
Many years ago, with a group of friends, we rented a 40 foot trawler style boat with a 15 foot beam. The downside was it had a single 120 HP diesel, no thrusters, and top speed was about 6 knots. It was a joy to dock! :) The upside was the autopilot. It held the course well and I am sure the units of today are a lot better.
On a smooth clear July day we left Hyannis for Nantucket and knew it would be about 4 hours of slow boating. Once we set the autopilot we were all in the back of the boat playing cards. We only had to look out every 1/2 hour or so, see that there was nothing in our area, or headed our way, for at least five miles (or as far as we could see) and go back to the game. It worked very well, even with the older technology. |
Less Fuel??

We went from a 6000 lb boat to a 32,000 lb boat, but at hull speed (8.5 knots) the bigger boat is pretty thrifty and gets about 2.8 nautical miles per gallon pretty much regardless of load or sea state. The smaller boat got 2.6ish statute miles per gallon at 32ish MPH, but that varied wildly depending on sea state and load. We are having a fantastic time. It's so cool to see whales/dolphins/seals/sunfish all the time (like almost every trip out) and the virtually unlimited ports of call make for interesting boating. I miss the warm water for swimming and I am tired of dodging lobster traps all the time though. |

Autopilot without a GPS input (gyro only) is really a misnomer and not autopilot at all, it is simply auto heading and maintains only the direction which the vessel is facing, not a course. In my opinion, for most recreational boaters, auto heading is a waste of money and a highly risky tool. If you are considering a similar system, spend the money and get a true autopilot system with both gyro and GPS (or even better, multiple GPS) input. Quote:

On Lake Erie, Long Island Sound and Buzzards Bay, I could set a heading for a destination 30-80 miles away and never touch the auto-pilot the whole way there. On the NH coast, if I set a heading for a port 10 miles away (like Islaes of Shoals from Hampton River), I'll probably makes at least 5 heading adjustments on the way there, excluding adjustments for lobster traps (I generally just adjust 10 degrees one way and 10 degrees the other way a few seconds later to avoid them). The currents generated by the 8-11 foot tides we regularly see are really strong, even miles out. |

Much like the technology in mentioned above in Tesla's cars; amazing if used responsibly. |
I have been using my auto pilot for over 10 years on Winni and a few ocean trips. As mentioned, it greatly reduces the boring constant corrections needed on an i/o driven boat. It goes where I tell it to go, either by a gps route or an individual heading. I've been in some very windy and strong currents and it will always correct to the course given.
Of course, I still have to make certain it is being told the CORRECT place to go. Either because I screwed up or something else has changed, like another boat wanting to go the same place. |
