Well I said it is a bitch not impossible, admittedly I often fish how I want to fish for enjoyment, if priority 1 was taking home a feed I would make a few different decisions.
But I digress,
The degree of difficulty depends on if you can leave your boat in gear unattended for a short time and go straight, in the moorings is different to in front of the front cliffs, a squid is easier than a 10 inch yakka that's determined to go around everything. How sleep deprived you are etc
As for your question,never used one BUT, if the boat can drive itself for a minute it would really help. My electric will work in the moorings and inside but in the backwash against the cliffs not so effective.
So I'm back to the PMD
