... the dolphin striker should provide some resistance from going forward - no?
In my case, no. I tied it to the end where the striker and post meet. I tied it is such a way that it stays at the end, away from the crossbar. It's a good suggestion though. I may try to move it down and try that. The downside is that I would loose some of the distance from the end of the pole to the boat. Worth a try though. Thanks!
