31' stepped hull cat - Build thread

[Fin-S]

Engines mounted - these were the last set available about 6 months ago so we bought them and put them in storage. Just as well with the supply chain issues!

We went with mechanical models - more difficult to get all the engine data / fuel consumption etc, but simpler and less to go wrong!

The dash - minus the wheel. 2 x 12" screens, autopilot, trim tabs, wireless charging station etc.

Ideal to run one screen full size and split the other one so when we chase tuna the full screen will be for the radar to pick up birds, and the other split between fish finder and map. Or switch when bottom fishing or running.

Ready for sea trials

Finally she got splashed.

As per normal, a few teething issues.
Redid the autopilot and steering hydraulics as the plumbing was incorrect,
Installed a Garmin black box (transducer was not compatible without it),
took out the seachest and replaced it with a manifold system to get cleaner water at high speed,
and sorted out the outlet from the tuna tubes as it was running onto the deck instead of motor well.

Then onto the motors - she was running 42 knots at WOT and easily hitting the limiter. It also seemed like the motors could be dropped a hole.

A week later and all the changes were done. 47knots at WOT with a heavy load. 32knots cruise at 4000.

And finally at her new home, Fujairah International Marine Club, UAE.
