The Sunsation 36 SS Open Bow Open Cockpit 2013 is a deep-V design and the Sunsation F-4 Standard 2008 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Sunsation F-4 Standard 2008 measures 43,0 feet overall (2008), giving it roughly 7,0 additional feet of deck space compared to the Sunsation 36 SS Open Bow Open Cockpit 2013 at 36,0 feet (2013). Weight tells a clearer story for trailering families: the Sunsation F-4 Standard 2008 tips the scales at 10 000 lbs - 2 100 lbs less than the Sunsation 36 SS Open Bow Open Cockpit 2013 at 7 900 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
For family outings this is probably the sharpest distinction between the two. The Sunsation F-4 Standard 2008 is rated for 13 passengers, while the Sunsation 36 SS Open Bow Open Cockpit 2013 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sunsation F-4 Standard 2008 could be the deciding factor.
Bottom line: Choose the Sunsation F-4 Standard 2008 if your priority is putting more people on the water - it handles 13 passengers and at 43,0 ft it has the deck room to back that rating up comfortably. The Sunsation 36 SS Open Bow Open Cockpit 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
