The gentleman who makes these is the original designer of the Vector downrigger. He sold that line which is owned by traxstech. I've spoke with him a few times great guy. I currently run the vectors and love them. I will definitely upgrade to his newest design.
I have the boat you are speaking of. The boat handles rough water well and I do like that it is a deep hull. My boat has a soft top not the hardtop. When trolling in rought water it does tend to get pushed around more than other boats. Some would say it's like a giant bobber. But I feel it fishs well.
