Local, on the water

Based in Mosman, working across Sydney Harbour and offshore

We're sailors and racers as much as we're technicians — the same instruments we calibrate on your boat are the ones we trust on our own deliveries and races. That means installs that make sense in the real world: cable runs that survive a seaway, displays you can actually read at night, and systems that get serviced properly, not just switched on.

Every project is handled from first conversation to final commissioning by the same small team, so nothing gets lost between the quote and the sea trial.
