How does the SP-48’s visibility kit compare with the radar reflectors on crewed boats?How much does the Coast Guard have to do before USV rules become enforceable?How does a dashboard-monitored drone boat hold station without a crew aboard?<\/p>\n
There\u2019s one rule on the water that pretty much every boater hears before they\u2019re allowed near a throttle. Keep a proper lookout. Someone on board watches what\u2019s around you the whole time, which kind of assumes there\u2019s a person on the boat to do the watching.<\/p>\n
So who\u2019s the lookout on a boat with nobody aboard?<\/p>\n
That\u2019s the question at the center of a report the National Transportation Safety Board put out on October 27. It covers a collision on Lake Erie that happened back on August 10, 2024, so the crash itself is more than two years old. What\u2019s new is the NTSB\u2019s verdict on it.<\/p>\n
Here\u2019s what happened. At about 7:12 p.m. that Saturday, a privately owned 45-foot Prestige 450 Flybridge cruiser was heading home to its marina at about 25 mph, roughly 6 miles east-southeast of Monroe, Michigan. It hit a 15.7-foot drone boat belonging to NOAA\u2019s Great Lakes Environmental Research Laboratory (GLERL).<\/p>\n
The drone boat got wound up in the cruiser\u2019s starboard propeller pod. The two were towed to a marina still stuck together.<\/p>\n
So what was a drone boat doing out there?<\/p>\n
The boat is a SeaTrac SP-48, built in 2021, and it\u2019s what the industry calls an uncrewed surface vessel, or USV. Think of it as a small boat that drives itself where you tell it, while a person on land keeps an eye on it through a computer dashboard. GLERL was using it to support monitoring of harmful algal bloom toxins in western Lake Erie, which is a pretty useful job for a boat this size.<\/p>\n
And it really is small. The NTSB puts it at 15.7 feet long and 4.6 feet wide, and it showed only about a foot of freeboard. Freeboard is the height from the waterline up to the deck, so we\u2019re talking about a hull that sticks up roughly to the middle of your shin.<\/p>\n
Solar paneling covers most of the deck and feeds a 6.75 kWh lithium-iron-phosphate battery. A single 1,000-watt electric motor pushes it along at up to 5 knots. If the yellow hull and solar panels look familiar, we covered a very similar 16-foot solar drone boat that went silent in the Gulf of Maine<\/a> back in October.<\/p>\n Autonoci\u00f3n Newsletter<\/p>\n No spam.

The hull is yellow, and the stern says UNCREWED SURFACE VESSEL in capital letters. A forward mast about 26 inches tall carries a small yellow flag that the NTSB estimates sat about 2.5 feet above the water, and GLERL added an aft mast with an all-around white light.<\/p>\n Its Class B AIS transponder was on, too. AIS is basically a radio beacon that puts your boat\u2019s name, position and heading on other boats\u2019 screens. The USV didn\u2019t carry a radar reflector, but it wasn\u2019t required to.<\/p>\n Drone boat vs. cruiser<\/p>\n 15.7 ft vs 45 ft<\/p>\n Length of the NOAA USV and of the recreational cruiser that hit it.<\/p>\n Source: NTSB, MIR-26-32<\/p>\n Freeboard<\/p>\n 1 ft<\/p>\n About how much of the USV\u2019s hull showed above the waterline.<\/p>\n Source: NTSB, MIR-26-32<\/p>\n Adapted hold<\/p>\n 150 ft<\/p>\n Radius of the holding area.

It just means how easy a boat is for other people to notice, whether that\u2019s by eye, by radar, by AIS or by sound. A boat can be bright yellow and still score badly if it\u2019s a foot tall and bobbing in 3-foot waves.<\/p>\n Those were the waves that evening, with wind at 18 knots gusting to 23. Sunset wasn\u2019t until 8:39 p.m., and the cruiser\u2019s operator told investigators the sun was off to his right. He also said anything sitting that low was impossible to pick out against the color of the lake.<\/p>\n Then there\u2019s the electronics. The cruiser\u2019s operator usually kept his radar dome folded on its hinge because it got in the way of his covered slip, so the radar wasn\u2019t available. The cruiser had no AIS either, and none was required.<\/p>\n Which means the drone boat\u2019s AIS signal had nobody to talk to. The NTSB says that in this case the USV\u2019s AIS and an optional radar reflector wouldn\u2019t have been effective. Frankly, that\u2019s a little unsettling, since the drone boat carried more visibility gear than anyone required of it.<\/p>\n Nobody was really watching it, either<\/p>\n The USV was in a mode GLERL calls adapted hold. Basically, you park it on a spot, let the wind and waves push it around, and once it drifts past a 150-foot circle, it motors back toward the middle at a 3-knot setting. The lead engineer told investigators it was really only doing about 2 to 2.5 knots. So it wasn\u2019t anchored. It was holding station, a bit like a dog on a long leash.<\/p>\n The pilot on shift was working from home, monitoring passively through the dashboard. The boat\u2019s four cameras were off. GLERL told the NTSB its main worries about running them for long stretches were cellular data getting throttled and battery drain. A collision-avoidance feature SeaTrac was still testing was turned off, and the AIS proximity alert can only warn about boats that broadcast AIS, which the cruiser didn\u2019t.<\/p>\n So what does having no lookout mean in practice? A lookout is someone whose job is to notice trouble coming and react in time. A dashboard nobody\u2019s actively watching and switched-off cameras don\u2019t really fill that role.<\/p>\n That\u2019s pretty much where the NTSB landed. Its probable cause blames two things: a drone boat other boaters couldn\u2019t readily see in that spot and those conditions, and a lack of active monitoring that, according to the NTSB\u2019s full report<\/a>, \u201cleft the USV without a proper lookout to avoid a collision.\u201d<\/p>\n You\u2019ll notice the probable cause doesn\u2019t land on the cruiser\u2019s operator. I\u2019m not going to put it there either.<\/p>\n The cruiser\u2019s operator hurt his foot, the one minor injury in the report. The drone boat\u2019s hull split in two, and it was declared a constructive total loss of about $186,000. The cruiser took about $100,000 in damage, including salvage.<\/p>\n So what does the NTSB want?<\/p>\n The two recommendations that matter most for everyone else on the water go to the Coast Guard. M-26-03 asks it to draw up a national set of standards for USVs covering how visible they are, how they avoid collisions and how they navigate safely. M-26-04 asks it to turn those standards into actual regulations.<\/p>\n That second one is arguably overdue. The report says the Coast Guard had no regulations for uncrewed surface vessels in US waters when the collision happened. Its 2026 work instruction counts only as guidance, and it leaves out small uncrewed systems operated by NOAA.<\/p>\n NOAA got three recommendations. M-26-05 and M-26-06 tell it to rewrite its Uncrewed Marine Systems Manual so its USVs are perceptible where they operate, and to test that with the people who run other boats in the area. M-26-07 says it should monitor these boats at a level that matches how autonomous they really are.<\/p>\n I\u2019d say the test-it-with-real-boaters idea is the smartest one in the bunch. It\u2019s a pretty cheap way to find out whether a boat that looks obvious to its engineers looks obvious to someone doing 25 mph through 3-foot waves.<\/p>\n SeaTrac got one, M-26-08, asking it to make the SP-48 easier to notice where practicable. The company now offers an optional reflection kit with a passive radar reflector and reflective tape, and the report says it had sold 25 SP-48s as of June 2026.<\/p>\n Twenty-five boats isn\u2019t a huge fleet. But that\u2019s one model from one builder, and drone boats will probably keep getting more common, from research boats like this one to defense types like the 19,800-pound drone boat that ran around the clock in an Australian port<\/a>.<\/p>\n We don\u2019t know yet how the Coast Guard will respond. The NTSB\u2019s investigation page<\/a> lists the case as completed, and the board issued all six recommendations in its October 27 announcement<\/a>, which puts M-26-03 and M-26-04 on the Coast Guard\u2019s desk.<\/p>\n B<\/p>\n You read 0 of 4 key points6 min \u00b7 1,378 words<\/p>\n How does a dashboard-monitored drone boat hold station without a crew aboard?<\/p>\n","protected":false},"excerpt":{"rendered":"B Key pointsIn contextAsk Key points generated with AI from the article and the AutoNotion archive.
