No. Under normal conditions it was a tried and true practice for us.
The reason we use 9/16 polysteel rope is that it actually holds less current and has less drag. We can go to a heavier rope, but it doesn't give us any more advantage because we're fishing in five-metre seas, and we usually knock off fishing when the seas are around six metres. Our vessel is a 22-metre vessel and we do multi-day trips and we fish up to 260 to 270 miles from land.
