Reducing sea clutter too much can hide real targets, not just waves.
Small boats, buoys, and weak echoes disappear first.
A “clean” radar screen can be more dangerous than a noisy one.
Always balance clutter control with gain, range, and visual lookout.
Because radar filters don’t prevent collisions — judgement does.

A power-driven vessel approaches another vessel from more than 22.5° abaft the beam, but due to alteration of course, a crossing situation later develops.
Which rule applies until finally past and clear?

“Boss, I’m ARPA. I’m not magic — I’m a calculator.
I build vectors, CPA, and TCPA from what you feed me: gyro heading + speed log + radar tracking.

If your gyro is drifting or lagging, or your ship is yawing, I don’t get a stable heading.
If your speed log is wrong, I assume the wrong own-ship speed and my relative motion math goes off.
Then my target vectors can look clean and my CPA/TCPA can look ‘safe’—while the real situation is actually getting worse.

So next time: verify gyro and log, steady the ship, and cross-check with raw radar/visual bearings.
I only give back the information you give me — feed me garbage, and I’ll output garbage.”
