I found a promising fast linear actuator but with 15% duty cycle.

Would this be a stupid decision to install?, worth a risk?, totally depends?

Show a link?

the duty cycle listed probably means it can be exceeded (at reduced speed) and/or exceeded with better cooling like a heatsink attached.

Otherwise, the duty cycle approaches 50% in rough weather, beyond that and the actuator is not fast enough. In lighter winds the duty cycle is much less.

The closest Ill get to rough seas is the wakes from power boats (inland lake). 
Mostly <15kt winds though can gust up to 25kts.
30ft racer/cruiser.

The worst that will happen is the motor overheats and burns out. You could add a heat sink around the motor or put a temperature sensor on the motor to protect it, the pypilot motor controller has optional input for temperature sensor for the motor. It probably only is going to overheat if you are near the max force the actuator can produce which is probably not the case.

If there really are many waves there is probably plenty of wind to cool the actuator, i doubt it would be a problem, but if it is working hard, touch it where the motor is and see how hot it is.

Thanks, I’ll give it a try.
