The future of racing is here.


Introducing The World’s First Robotic Mark.

Now you can set up your course faster, easier and more accurately than ever before. MarkSetBot is self-propelled and uses GPS technology to zero in on a specific location and stay there until you tell it to move. Best of all, you control everything with your smart phone.

The Future of Racing Is Here.

We’ve taken the “a” out of the mark set boat and turned it into a bot (as well as the “a” for aggravation). Now, no matter the wind; no matter the race; no matter the size of your race committee, with MarkSetBot you just set it and forget it. If the wind changes direction, the RC can reposition the mark and pin just by entering the new wind direction, so course changes are handled automatically without a mark boat crew.

Benefits and Features.

Faster course set-up
Perfect placement of starting pin and mark
Mobile GPS Technology
No anchor needed
Effortless repositioning


Founder and creator Kevin Morin conceptualized MarkSetBot™ while racing on Cass Lake (Michigan) at the Pontiac Yacht Club, where he was a member. Cass Lake is a challenging place to do Race Committee work, as the wind is very shifty and there are many areas that are too deep to set an anchor. Often the Race Committee is forced to set a course that isn’t ideal, because it’s the only location where a mark can be set. Additionally, every racer at the club must volunteer for Race Committee twice a year.  Kevin figured if he could replace the mark set boat, each racer would only have to volunteer once a year, which would mean one extra day of racing for everyone!

Kevin gives credit for his inspiration to continue the project to a retired engineer and old family friend, the late Bill Margolin. Bill had a way of dissecting problems, and during the months before he passed away, they talked about the concept for MarkSetBot™. While he was fragile, he still loved to solve problems, so Kevin brought a prototype to the hospital one day. Bill suggested ditching the preliminary prototype and creating a way to provide thrust via a propeller on a pivot.  At the time, Kevin thought he was crazy, but several weeks later, when he saw a GPS-based trolling motor he knew that was the way to go.

In 2014, the first functional prototype was developed and was called Robobuoy™.  Robobuoy™ is the name of our core technology and MarkSetBot™ is our sailing industry version of the product. In 2016, ProNav Marine of Houghton, MI and MarkSetBot teamed together to improve on the initial prototype.  This led to a beta at 6 clubs in the summer of 2017 and production starting in 2018.

The Solution for a Common Race Problem.

Set up your course faster, easier and more accurately than ever before.

Self-propels and uses GPS technology.



Don Glover, 2017

“I was very impressed with MarkSetBot on Saturday.  The mark seemed to hold position very nicely, in what I thought were challenging conditions of winds nearing 20 mph early in the afternoon and seas that were 4-5 feet.  In such conditions, an inflatable mark tends to move around on the wave face, whereas the MarkSetBot did not seem to be tossed around like an inflatable. I really liked that the RC could quickly adjust course length between races without a mark boat.

Before the race, there were many doubters in the crowd, but MarkSetBot worked out just fine.  I would have absolutely no reservations about using it again.  I am a believer!”


Russell Coutts, 2019

MarkSetBot’s participation in SailGP has brought us to the attention of Russell Coutts, CEO of SailGP. “I just saw the brilliant technology from MarkSetBot which is a revolutionary course laying system using robotic technology.”, Coutts said.

In speaking about MarkSetBot’s value outside of SailGP, Coutts mentioned that “We immediately have decided we need some of those in our youth program in New Zealand, that’s for sure. For anyone that’s been involved with pulling up anchor chains and so-forth, getting to this MarkSetBot, it’s definitely a great solution.”


Ken Read, 2020

“I recently did a Club-Swan 50 event and they used really cool self-propelled, no anchor GPS-controlled race marks – they were working in current and good breeze and waves and it made for simple racecourse adjustments and far fewer people needed to run the races. If you are a starting-line perfectionist PRO this gives you free reign to move the mark up to about five minutes before the start and still allow people to ping the pin.

Fewer people. Fewer anchor lines. Fewer boats needed. Less fuel. I couldn’t believe how something like this wouldn’t be cost-effective for all yacht clubs around the globe.”

Is MarkSetBot the future of race management?

New technologies are often received with doubt and controversy in sailboat racing.  They can over-complicate and add even more expense to the sport. And while the technologies coming out of the top of the sport, take foiling in the America’s Cup for example, are...

The SuperBot is alive!

MarkSetBot, through three different generations, has maintained a very similar form-factor throughout. Up to this point, the biggest change was from V2 to V3, where the aluminum frame connecting the two side pontoons was ditched in favor of a one-piece inflatable...
