Artificial intelligence continues to move from the fringes of marine technology into the everyday tools sailors and professional mariners rely on. This week, Hefring Marine and SEA.AI announced a new partnership aimed at bringing AI enhanced vision and onboard analytics together to elevate safety and situational awareness at sea.

Hefring Marine, an Icelandic marine technology company known for its intelligent maritime analytics, will integrate SEA.AI’s machine vision collision avoidance technology with its IMAS platform. The result is a combined system designed to help operators better understand what is happening both around the boat and within it.

Hefring Marine’s IMAS platform uses AI sensor data and edge computing to provide real time operational intelligence. It is designed to support safer decision making while improving efficiency and sustainability across a wide range of vessels. SEA.AI brings a different but complementary capability to the table, using optical and thermal cameras paired with artificial intelligence to detect and identify floating objects in real time, including hazards that can be difficult to spot by eye or radar alone.

Together, we are setting a new standard for maritime safety and performance.”

By integrating the two systems, operators gain a more complete picture of both external risks and onboard performance. The companies say the combined technology is intended to improve situational awareness, streamline operations and support compliance with increasingly strict environmental regulations by helping crews operate more efficiently.

SEA.AI CEO Marcus Warrelmann sees the partnership as a natural extension of his company’s focus on maritime machine vision. “Partnering with Hefring Marine solidifies SEA.AI’s position as a pioneer in maritime smart vision technology,” Warrelmann said. “By joining forces with such an advanced analytics platform, we are creating an integrated ecosystem that addresses the full spectrum of maritime operational needs.”

SEA.AI has been developing machine vision systems for maritime use since 2018, offering solutions that combine AI with optical and thermal sensors for recreational commercial and government vessels. Hefring Marine’s IMAS platform is already used across multiple workboat sectors to support safety fuel efficiency and data driven fleet management.

For cruising sailors and offshore operators alike, the collaboration signals how quickly AI based tools are becoming more integrated into onboard systems. Rather than standalone gadgets, future safety technology increasingly points toward unified platforms that help crews see more, know more, and respond faster at sea.

Weems & Plath has introduced a first-of-its-kind LED steaming and deck light designed with sailors in mind. The new OGM LX Steaming/Deck Light combines a USCG-certified masthead steaming light with an integrated deck light capable of switching between red and white illumination at the flip of a switch.

For cruising sailors, the ability to shift between red and white light on deck is especially practical. Red light preserves night vision and minimizes glare during overnight passages, while white light makes it easier to handle sails, lines and hardware when detailed work is required. Traditionally, these functions have required separate fixtures and additional wiring.

“An OGM Steaming/Deck Light has been a highly requested item among our customers,” says Michael Flanagan, president and owner of Weems & Plath. “When we started designing it, we realized how cool it would be to have a deck light that offered the option of either red or white illumination. As far as we are aware, there are no other steaming/deck lights on the market that offer that capability.”

Professional sailor on a yacht
Modern sailboat cockpits can rival flight decks, packed with screens and instruments—impressive tools, until the power goes out. bublikhaus/stock.adobe.com

Last year, I had the opportunity to operate the American Magic simulator, which had the exact same configuration as the racing yacht itself. I felt like I was in the cockpit of a spacecraft. All the screens, buttons, readouts, digital files, and headsets for communication reminded me of Buck Rogers and Star Trek.

I’m sure that the computers and artificial intelligence helped the sailors in their quest to win the America’s Cup, but I was bewildered. One of the coaches said that today’s better Cup ­helmsmen are skilled video-game players, and often aircraft pilots comfortable with sophisticated instrumentation.

A few days after my time in the simulator, I enjoyed a sail on a brisk winter’s day aboard my 32-foot sloop. My complete package of instruments includes a compass, a VHS radio and a nautical chart. The sharp contrast between Whirlwind and the America’s Cup yachts made me think about the appropriate amount of ­instrumentation that should be aboard a sailboat.

We live in an age when computers, GPS, chart plotters, accurate instruments and navigational tools are ubiquitous. On bigger boats, the chart table contains a labyrinth of electronic tools that are great until something goes wrong. Then what? 

LOWER YOUR RATES
Taking a boating safety course won’t just make you a better skipper. It could also help you save big on insurance.

Safety Tip Provided by the U.S. Coast Guard

Stan Honey, one of the most successful racing navigators of our era, says that he always carries paper charts, even with the availability of electronic aids. For my part, before every race or cruising adventure, I take the time to study charts so that I have a mental image of the waters. I particularly note shallow spots and places with large tides and swift currents. If a boat loses power or develops a short circuit, paper charts will save the day. I like to use waterproof charts on deck. Paper charts need to be stored in a dry space. I use plastic folders.

GPS is amazingly accurate and easy to use. It can indicate a boat’s position and speed, help to add waypoints, and assist in calculating course and distance to a destination. On my cruising boats, I’ve always had at least two GPS systems with an abundant supply of batteries. When sailing on waters noted for fog, a GPS is a fundamental aid. 

Eldridge Tide and Pilot Book, published annually for 150 years, is another invaluable guide. It includes tides and currents, celestial-body timings, navigational rules, piloting tips, emergency first aid, marine weather guidance, tips on electronic navigation, light lists, and coastal piloting ­information for mariners from Nova Scotia to Key West, Florida. The yellow-cover book is a must for any chart table. Plus, nifty stories are sprinkled throughout the text. 

Reeds Nautical Almanac is another useful publication for sailors. I also stock up on cruising guides for the area in which I will be sailing. The US Coast Guard publishes the Coast Pilot series for the entire United States in eight volumes. This information is helpful when entering harbors, to avoid dangers to navigation.  

For many mariners, an important volume is American Practical Navigator, first published by Nathaniel Bowditch in 1802. It is updated frequently and has all the ­information for celestial navigation and ­piloting. I still have my copy of the 1,514-page 1968 edition with hundreds of earmarked pages. The newer additions are slimmed down to 950 pages.

A compass has been a trusted tool for sailors since 200 B.C. In the year 1120, the compass was used for marine navigation using Earth’s electromagnetic field. The compass is reliable and easy to use, but it needs to be corrected for deviation from a boat’s magnetic forces and variation for the differences in the magnetic fields across the globe. It’s important to have a professional adjust the compass so that it is accurate. Modern electronic compasses with digital readouts are helpful tools. I also keep a hand bearing compass on board if I need to do some piloting.

WEAR A LIFE JACKET
Everyone, even strong swimmers, needs to wear a life jacket at all times when on the water. It is extremely difficult to put a life jacket on once you fall into the water.

Safety Tip Provided by the U.S. Coast Guard

Essential instruments on sailboats are a boatspeed indicator, windspeed and direction indicators, and a fathometer. I like to know the wind velocity and direction, the angle of the apparent wind, the depth of the water, and how fast the boat is moving. My philosophy is to keep instrumentation simple so that I can spend my time enjoying the sailing.  

On racing boats, the appetite for ­additional information never seems to be ­satisfied. A navigator will sit near the helm with a tablet to calculate wind trends, watch the changing course and bearing to the next mark, continually calculate the direction and speed of currents, monitor the state of tidal rise, and study optimal ­performance data. At least one ­crewmember focuses ­exclusively on the data. All this information is interesting but, in my view, not necessary for most enthusiasts. 

A barometer indicates changes in the weather. NOAA Weather Radio, found on VHS radio, and satellite sources such as Starlink give up-to-date weather forecasts. Cellphones are reliable, with connectivity available in most of the country. The important thing is to keep your cellphone dry and secure. Many cellphones are on the bottom of our bays and lakes.

Binoculars are a wonderful aid, whether used for navigation or simply observing the surroundings. When binoculars come on deck, notice how frequently they are passed around to the crew. Everyone wants a look.

A masthead wind indicator is my most helpful aid when sailing. I look aloft frequently to check that my sails are trimmed properly to the direction of the wind. The masthead fly is a particularly useful reference when maneuvering and changing course. An osprey once landed on my masthead fly and broke it. I felt hobbled without it. My next masthead fly included a stiff shaft extending upward. I haven’t been ­bedeviled by a bird since.

CARRY A BEACON
Satellite beacons such as EPIRBs or PLBs allow boaters to transmit distress signals and their exact coordinates from anywhere on the planet, no cell service required. It may be the best $400 you ever spend.

Safety Tip Provided by the U.S. Coast Guard

A sextant is still a good navigational aid, but most sailors prefer the convenience of GPS. It takes practice to get a precise fix using a sextant, along with an accurate timepiece and a set of tables for calculating position. Still, taking a course on celestial navigation is beneficial. It took me a few years as a maritime cadet to become proficient using a sextant. If I could get a celestial fix within 5 miles of my location, I was happy.

Sailors who want to install a full set of electronics around a chart table should hire a professional. Clearly marked wires will help when repairs are necessary. The best systems should be minimal and easy to use. 

Take the time to learn how to use each piece of equipment. So start with a ­compass, and expand from there.
