Thanks guys @Vikingstaff that sounds almost identical to what I'm seeing. I contacted the mechanic who has worked on it and said this is typical, but it's considered a 24' by Bennington even though it's really only the middle pontoon that's close to 24'.
I am currently about to purchase a 2015 Bennington SSLX24 that it's excellent condition and am very excited about it. However, I've noticed some issues in the length and am just curious, having not owned a Bennington before, how they measure the total length. My old Pontoon was a 25' pontoon...
