Please remember that all of us were frustrated newbies at some point. We feel your pain!
Blown anchors (for me) almost always seem to be a case of too much power too early. BTW, we all blew them with amazing regularity as we were beginning.
It seems natural that we would: You're swinging a longer rod than your ever used before and you have 30-60 ft of head, tip and leader beyond the last guide. It makes intuitive sense to rush everything.
But a smooth forward stroke (which is much easier to do if you have a smooth set-up stroke, too), hitting the gas pedal late, not early, is a good place to start to fix blown anchors. Of course, you'll end up with too little acceleration and a line that goes nowhere, but that is part of the learning curve.
My suggestion is to start with a short line and very smooth movements.
But, of course, I wanted to try to bomb something out there, and ignored my own advice.
All the same, it is still good advice.
Where on Vancouver Island, btw? Will be there this summer for a family wedding.
