Case Study: How Compass Calibration Restored Safe Navigation for a Yacht in Tivat
Precise navigation is at the heart of safe yachting. Even the most advanced GPS or autopilot system relies on an accurate compass to keep a vessel on course. At YachtService.me, based in Tivat, Montenegro, we see firsthand how unnoticed compass errors can create real risks. This case study highlights how our team diagnosed and fixed navigation issues for a client whose yacht suffered from unreliable compass readings in Boka Bay.
The Client’s Problem: Mysterious Heading Errors
A 20-meter sailing yacht arrived at our service dock with a recurring issue: the compass readings were consistently off by up to 15 degrees. The owner reported:
The Client’s Problem: Mysterious Heading Errors
A 20-meter sailing yacht arrived at our service dock with a recurring issue: the compass readings were consistently off by up to 15 degrees. The owner reported:
- Incorrect course plotting when crossing Boka Bay.
- Autopilot veering unexpectedly during longer passages.
- GPS integration errors causing delays in heading corrections.
Step 1 – Initial Inspection
Our yacht technicians began with a physical check of the compass. The housing showed no cracks, but the yacht’s helm area had recently been refitted with new electronic equipment. This immediately suggested possible magnetic interference.
We also verified the installation angle and ensured the compass was correctly mounted—an often-overlooked detail that can lead to misalignment.
Step 2 – Detecting Magnetic Interference
Using diagnostic tools, we identified interference coming from a newly installed speaker and nearby metallic fittings. Both were within the compass’s sensitive range, causing significant deviation.
Our team advised repositioning the electronics and applying shielding solutions to minimize interference.
Step 3 – Swinging the Compass
With the interference addressed, we performed a 360-degree swing test in calm waters outside Porto Montenegro. At each heading, we measured compass deviation against GPS and noted errors. The results confirmed irregular deviation patterns that required correction.
Step 4 – Adjustments & Deviation Card Update
We carefully adjusted the compass, reducing deviations to within a few degrees. Then, we prepared a new deviation card, giving the captain reliable correction values for every heading—a vital tool for safe navigation.
Step 5 – Integration with Autopilot & GPS
Next, we synchronized the recalibrated compass with the yacht’s autopilot and GPS systems. Before calibration, the autopilot had been receiving flawed heading data, leading to unnecessary course changes. After integration, heading responses were smooth, precise, and immediate.
Step 6 – Testing Under Real Conditions
We tested the system on a passage across the bay. The compass readings matched GPS bearings perfectly, and the autopilot maintained a steady course without veering. The yacht’s owner immediately noticed the difference: “For the first time in months, I feel confident relying on my navigation instruments.”
Common Compass Issues Our Team Resolves
This case was a clear example of magnetic interference, but our technicians regularly deal with:

When captains think of essential onboard electronics, radar and chartplotters often come first. Yet, a speed log—though less glamorous—is just as critical for navigation accuracy and fuel efficiency. Without reliable speed data, trip planning, autopilot performance, and even fuel management can become guesswork.
Yacht owners are increasingly turning to renewable energy solutions to support their onboard power needs. Among these, yacht wind generators stand out as a sustainable, eco-friendly option that provides continuous, clean energy while reducing reliance on fuel-powered systems. At YachtService.me in Tivat, Montenegro, we specialize in the installation and maintenance of wind generators, ensuring yachts remain efficient, reliable, and environmentally friendly.
