I got to go out and test our Donzi ZR last week. I must say it is one on the nicest handling boats I have ever driven. There was 3-5's out there. The boat handels the water great and turns well also.
We had some people riding in the back and I must say they felt secure with the handles, but the topic did get brought up though that if you ever hooked hard and hit one it could be ulgy. The foot rest seemed to be fine and is a great feature. Especially like the eletric ones for driver/throttleman.
All in all, the boat is great and is one of my favorites!
