I did not have problems with weathercocking and i don't really have any refined strokes. I did not feel uncomfortable in boat wake or poor conditions. handled like a champ. It's a pretty dry ride for me, but in chop and wind you will get wet. a fair tradeoff for staying in the boat when things get rough. The boat tracks very well for a 13 footer. I'm comfortable in the boat for hours but its not quite big enough to bring my 50# dog on anything but a few minute paddle...
My only two issues: the carry handles at the cockpit are directly across from one another, which makes balancing the boat in the air difficult when picking the boat up and loading on a car top by yourself. I wish the foot pegs were more angled for comfort. I've never used the storage but no water has entered.
It's a keeper.
I can comfortably paddle this boat 4.5 MPH for an extended period of time and can hold 5 MPH for over an hour on flat water, with a sprinting speed topping out just over 6 MPH. The only other boat I can compare it to is a 10' WS Tarpon 100, which I could comfortably paddle between 3.5 to 4 mph but not over 4 for long.
For my needs, I need a faster boat as I found I enjoy racing. However, I will keep this one for leisure paddles because it is comfortable, very stable, and despite some reviews, relatively dry despite my weight. On a calm day, I will not take on any water.
One thing about this boat is that is handles more like a touring boat and is not nimble at all so don't think it will handle tight turns down whitewater unless you are an advanced paddler.
All in all a great boat.
That said, I really did like this boat's combination of features. It was a bit quicker and tracked straighter than the other kayaks of comparable size. Speed wise it a little faster than the Tarpon 140 for the same effort.
One clear difference was the seating. The Vector has a seat straight out of Necky's sit inside kayaks. There might be pros and cons to this. I really thought the seat bottom was very (as in all-day) comfortable, but the seat back might be low for some people. You really won't know unless you take it out for a few hours I suppose.
The end result? I'm ordering one of these. It's perfect for my open bay use, not too tiring for my coastal touring, and not too long for the occasional river run.
I'll update this review or submit another once I have more hours on it...
