I chose the 48 YF because you can single hand it, it has a lot of deck space, enclosed lower helm that is not in the salon (it is as high as the fly bridge on most sportfish) and the fly bridge is as high as a tuna tower when the weather is nice. You can see what is going on in the cockpit from either position. The cockpit is small but it does have a tuna door and large outriggers. One of my changes (one day) is to extend the cockpit another 3 or 4 feet and add a bait station/ tackle center, along with an above deck fish cooler. The walk around deck can't be beat, and sun bathers have plenty of space on the salon roof. The visibility from the salon is fantastic for anyone hanging out there while cruising.
The downside for this model. Only made for two years, and they are very old and slow as originally equipped. Unless you find one that was a fresh water queen, most of them are dogged out and need everything replaced. The original interior layout is not a good use of space, unless everyone likes sleeping in single beds (not!). I did a redesign to make two full size bed staterooms and two heads, the master head is huge, plenty of real storage, and the galley got a redesign. The salon will convert into another stateroom for when we have more than two couples aboard. The swim platform and fresh water washdown, make water sports a reality. It is best overall design unless you are a hardcore Marlin fisherman, but for everything else, it is great. You can have a large number of people aboard for a booze cruise, or you can liveaboard and have plenty of space. I mostly fish for tuna, wahoo, and king mackerel on standup gear, with a couple of buddies, and this boat is adequate but not ideal. The bigger cockpit will solve that problem. I repowered to get the cruise speed I wanted and still get decent mileage at slow speeds. The 58 was too big for my needs. The 53 was too heavy to get the cruise without resorting to massive power. The 48 was just right.
