Hello,
Firstly, wow, what an amazing forum, so much knowledge.
I am a proud new owner of a HB Helix 9 with Mega SI+ transom mounted ducer, which I intend on using for seabed habitat mapping in seawater approx 10m to 50m deep.
I am at a fairly exposed coastal location, so the sea is rarely as calm as I would like it, which means the number of days where the sea is flat enough to capture really good SI data are limited.
I am therefore thinking that a towfish would help removing the roll and pitch of the boat (21ft motor cruiser with outboard).
Does anyone have any recommendations for a setup to simply remove the motion of the boat. I don't need to get the ducer much deeper, just remove the wave action. I also have a down rigger on the boat.
I am considering lowering the down rigger just enough to clear the outboard, then streaming a towfish 5m or 10m behind it?
Would such a setup achieve my objective of steadying the ducer from the motion of the boat?
All and any comments or advice greatly appreciated.
Thank you
Tim
