Yes. Stiction was an enemy of some of my attempts. Then when the inertia is overcome it becomes ballistic and goes past the idel point.
The mention of the rollcentre of the yacht and the pivot of the device being separate is also an issue.

Good luck with anything with motors. The video will pick up the noise. Try using a DSLR in autofocus when videoing if you rely in the internal mic.

I design and make my own brushless gimbals for use under multirotor UAV's. They would work just the same on the yacht. I must try it out this summer and see how it goes.

Can we see a photo of your brushless gimbal?

What would the "brushes" do if it had them? I understand (commutator) brushes in motors...

Do you have a web site where you show your gimbal designs ?

Brushless motors use a synthesised multiphase signal to provide rotational motion. RC electric flight made these motors very popular over the past 10 years and now they are being used to replace very noisy mechanical servos as you don't need a gear train and noisy DC motors to position a mechanical arm as it can be done through holding a fixed signal on the stator windings.

I worked on gun targeting systems that used exactly the same principles more than 20 years ago, the guns were a little bigger, 105mm, 80mm tank weapons and 20mm and 50 calibre cannons on helicopters. Those systems were geared several hundred to one so the positional accuracy was pretty impressive.

Have a look at hobby king

http://www.hobbyking.com/hobbyking/store/__974__973__FPV_Telemetry-Brushless_Gimbals.html

Most of their stock items are designed for the go-pro and be aware that some are sold without the necessary IMU ( gyro electronics ) and motor driver boards which are required to make a system.

Lovely images. You don't have one of Scotland's Haven (along from Gills Bay) have you - a memory from my childhood just popped into my head the other day.

Have you got a web site where you show information about your gimbal setup ?

OK, I am familiar with "gimbal" as applied to a two or three axis mount, relying on gravity or gyro for orientation. Not to a servo system. So it is the servo motors that are brushless...

A bit like those contractions that omit the crucial words and leave qualifiers. Best I remember was years ago when a TV critic referred to "watching the cathode". (Short for CRT.) Which to me meant checking that the CRT cathode heater was working in a failed TV...

A hand held gimbal would seem to be the answer; http://www.feiyu-tech.com/G4-en.php
It could be clamped to the pulpit/pushpit. However, a very expensive option if you don't have a Gopro. I was thinking to use my Nikon AW110 but its more than twice the weight of the GoPro so I guess the brushless motors would not be strong enough.
