Tech Talk #4 – Smart Connectivity: When Your Boat Starts Talking Back 📡⚓

From smart homes to smart boats, the marine world is embracing a wave of connectivity that’s transforming life onboard. What once felt like science fiction — remotely starting your heater before you even arrive, or getting an alert if your bilge pump kicks in — is now a reality for cruisers of all levels.

In this edition of Tech Talk, guest writer Doruk Kocuk explores how integrated systems, shared data languages, and smart devices are changing the way we maintain, monitor, and enjoy our boats. Whether you’re a tech enthusiast or a traditionalist, this shift is one every sailor will soon encounter.

From Smart Homes to Smart Boats 🏠➡️⛵

Homes are getting smarter every day. From voice-activated lights to automated climate control, connected devices have become part of daily life. Platforms like Home Assistant tie it all together into one neat interface, making life easier and more efficient.

The same thinking has made its way into boats — and it’s not just for luxury yachts. Connectivity can make any vessel safer, easier to maintain, and more enjoyable to use.

A Shift You Can See at Boat Shows 🎪🚤

As a frequent visitor to the big boat shows, I see the change every year. More and more companies are centering their new products around connectivity. Not seeing a new product from your manufacturer every year at the show was a bit disappointing but now they have new features to add every now and then.

Back in the 90s, a diesel heater with a pre-programmable analog control panel felt like rocket science. Now, almost everything is getting online. You used to be able to set which days your diesel heater would run and for how long.

Now, you can start it remotely before you even board the plane to your floating home.

Weekly flushing your watermaker was once a carefully planned task, often relying on a friendly neighbour at the marina. Now it’s just a tap on your phone — from anywhere.

The Evolution of Onboard Systems ⚙️💡

Some brands have added proprietary internet gateways to make existing products smarter. Others have built future-proof gear from the start.

Take tank senders as an example:

• Then: purely analog, feeding a single round gauge.

• Phase 1: digital converters translating analog signals.

• Now: many senders speak NMEA2000 or CAN bus directly.

The Rise of a Shared Language 🗣️🖥️

The most forward-thinking companies designed their systems so even third-party devices could talk to them.

Our first boat, a traditional Greek wooden Tirhandil (Trechantiri), had a tiny helm crowded with separate analog gauges for each piece of equipment.

Now, nearly all devices feed their data into the chartplotter — the MFD — using the same language: NMEA2000. Boats have moved from a collection of isolated systems to an integrated network.

What Connectivity Brings You 📢📊

• Remote bilge water alerts

• Intrusion and movement detection

• Fridge and freezer monitoring — know instantly if temperatures rise, so you can save that mahi-mahi before it turns into a nightmare

• Remote battery monitoring — get alerts if voltage drops, charging stops, or something starts draining your power unexpectedly

• Humidity and temperature monitoring

• …and the list keeps growing

And Sometimes… Just for Fun 😏🚽

One marine toilet brand now lets you flush it from a Bluetooth app.

Is that practical or just a party trick? That’s for you to decide.

The Bottom Line 📈⚓

From safety to comfort, from convenience to the slightly absurd, connectivity is reshaping how we use our boats.

It’s no longer about each device doing its own job in isolation — it’s about everything talking to each other, and to you.

Is Your Boat Ready to Talk Back?

The leap from analog to fully connected systems has been dramatic — and it’s only accelerating. Whether you’re outfitting a brand-new yacht or upgrading a trusty cruiser, embracing connectivity can make your boat more efficient, safer, and even more enjoyable.

But like all tech trends, the trick is knowing which innovations genuinely improve life at sea — and which ones are just shiny distractions. In the coming years, the line between “home automation” and “boat automation” will blur even more, and we’ll be here at Sailoscope to help you navigate it.
