Risks such as theft, water intrusion, or unauthorized access generate understandable concerns for boat owners. However, connectivity provides the opportunity to address these worries through remote monitoring.

Here is an illustration of the data you can gather using your standard Seanapps package:

GPS Location: Define a customized mooring area and receive alerts if your boat departs from its designated location or moves beyond its marina.

Water Intrusion Alert: Utilizing the bilge water presence detector, receive notifications when the water level becomes too high, and your bilge pump fails to activate.

For an added layer of security, consider augmenting your Seanapps equipment with supplementary sensors: motion detectors, anti-theft measures for dinghies, anti-theft measures for outboard motors, and door opening alerts.


Who hasn’t fantasized about the prospect of sharing their maritime exploits with loved ones? Whether you’re enthralled by speed or revel in long-haul journeys, the connected boat offers you the opportunity to document your sea performances (maximum speed, average speed, distance traveled, depth, etc.) and your routes directly on your phone. It truly enhances your experience, allowing you to assess your navigational progress, archive cruise routes, and share your accomplishments with friends upon your return to port!

Here is an illustration of the data you can gather using your standard Seanapps package:

They already trust Seanapps:


“My dealership was alerted by Seanapps that there was a diesel leak on my Prestige 520. He was able to intervene quickly and perform the necessary repairs to have the boat ready to sail whenever I wanted.”


“Seanapps allowed me to be notified when my boat came off its mooring during a storm. I was able to get to the scene quickly and locate it without any problems”


While I was away, the 220v shore power supply on my Jeanneau DB/43 was disconnected. Fortunately, my dealer was alerted directly on the Seanapps app and quickly reconnected the shore power. Thanks to Seanapps, the boat’s batteries were not discharged and I was able to enjoy my boat as soon as I arrived in port.


” Seanapps is brilliant! The power in my marina was inadvertently disconnected recenty. Seanapps alerted me about the low battery levels, which prompted me to come to my boat to charge my batteries with the generator. I also informed the marina of the problem. No doubt that helped out a few other boats as well. It saved me buying new batteries. A great app to have !”


“I have plans to resell my boat. Thanks to Seanapps, I now have a complete history of my maintenance book that I could share with the potential buyer.”
