It is pretty normal for a lot of small boats.

I *think* it comes down to overcorrecting: A boat doesn't react immediately to steering input (especially at slow speeds), and most people will crank in too much correction before the boat reacts. That sets it off in the other direction, and the problem is repeated.

Try allowing the boat to drift wherever it's going, give a slight correction, and wait and see where it wants to go then.

Use more power the boat has insufficent forward movement to allow for proper control

Ballast!

The more water the boat displaces, the better the straight line tracking should be.
Try more gear/people/dog/tackle etc near the stern!

Tight lines

I am more than happy to come and see if I can fix the problem. The call out charge is 50 I probably won't do anything to fix it and I may well piss in your handbasin.

Very common on RIBs at low speed as already mentioned and on BWM's it's more likely than most. A drop down temporary rudder might well help a little.

is this problem helped by small bursts of higher throttle rather than a continuous low throttle?

Wasn't a dig! I had a Deepsea 17 a few years ago and was a great little boat, but compaired to other makes of that size I've driven, slow speed manouvering wasn't the greatest. I just figured that it was the bow design that was different and was probably the reason for it. I could be wrong but am confident that handling was definatly more hard work at 5-10 knotts than others.
