The Ministry of Economic Development has granted SailADV the PATENT CERTIFICATE FOR INDUSTRIAL INVENTION RELATING TO THE FREEBOARD METER.

It is an instrument that is able to measure the height of the hull part perpendicularly and above the waterline by performing an accurate freeboard acquisition.
It is related to displacement and to the weight of the vessel. Therefore, the measurement of the freeboard is essential to calculate the weight of the boat and to understand if the boat itself is properly loaded.
Our Free Board is able to overcome most of the drawbacks given by the measurement methodology currently in place which is manual.
The data coming from the sensors placed on the instrument are sent to the control unit which processes them, allowing the cancellation of the wave motion with filtering operations, thus obtaining a precise and repeatable measurement.

Yacht vibration analysis

A vibration analysis is a pivotal process very important for vessels and yachts, intended to measure vibration levels and frequencies of machinery. All the collected data give us info to discover how healthy are the systems and their single components.
It all starts with using an accelerometer to measure vibrations.

Each time a machine is working it makes vibrations that the accelerometer or other sensors can detect which are sent directly into a data collector (software) which records the signal as either amplitude vs. time (known as time waveform), amplitude vs. frequency (known as fast Fourier transform), or both.

Vibration analysis can detect problems in a vessel such as:

  • Imbalance
  • Bearing failures
  • Mechanical looseness
  • Misalignment
  • Resonance and natural frequencies
  • Electrical motor faults
  • Bent shafts
  • Gearbox failures
  • Empty space or bubbles (cavitation) in pumps/propellers
  • Critical speeds

SailADV, thanks to its own high frequency multichannel spectrum analyzer H-SPECTRUM (complying with the international Standards ISO 2631 – ISO Standard 10816), is able to acquire at the same time all the operating parameters of the yacht system, optimizing yacht machinery performance and sharing them immediately with the Client.
