I bought this one last summer...
I stand 6'4"s tall and weigh 215 lbs...It is a sun dolphin 4 person with adjustable seats... I have had my wife and both boys in it with me and it was FULL... I really do enjoy it for just tooling around, but working out of it by myself can be a chore..
Never fished from it, but it does have rod holders...Fishing would have to be done from a seated position IMHO..
Examples of working out of it being a chore...Basically standing up in one is not going to happen easily or safely...Moving diffusers in cold water from a seated position without bringing them in the boat causes the inability of steering...You really have to pedal also to get through the water because of the drag...
It does work well for just tooling spraying algae or cleaning the edges of the pond of debris...
One other thing... In heavy rain it will sink below the seam and take on water internally which can make it fun to drag out by yourself to let drain...
