The console certainly looks like a Northcraft (last picture on this eBay advert
). But I can't find a photo showing that vertical bit of hull coming down from the tubes.
On the other hand, if I do a Google image search for "Northcraft Seasport 5.5", I get this remarkably familiar thumbnail from eBay.
If I then do a reverse image search, I get eBay again, some fraudulent-looking sites, and a Gumtree ad which contains some of your other images.
The Gumtree ad doesn't include "Northcraft" in the description, and I can't find the eBay one.
