I am looking at a new Phoenix and trying to decide between the 721 or 920. If I understand correctly from steering wheel back they are very similar/same. I am most interested in the front deck size. I will regularly be fishing 3 people in the boat. What would you guys think would work better the longer deck of the 721 or the wider deck of the 920? The lake I have my boat on has a 21 ft size limit on boats and a 45 mph speed limit so deck size is most important and the 921 won't work. Thoughts?
