Sonic never made a 44SS but rather a 42/45 SS.
If it was the Shogren boat you are talking about I went to the Bahamas on a poker run in July and that boat was there. It was absolutely spotless when I saw it last summer. The boat ran good and has a killer bimini top that covers the whole cockpit.
It is a nice boat but will feel like a sled compared to a 29 Formula and you will surely miss your 5 year Formula warranty when those 9 year old triples start giving you trouble.
It also is missing a generator which was pretty standard on big cabin boats like that.
