They are a glastron, Father-in-law just moved off of Big Carnelian lake (North of Stillwater) he has a Sx175 now, nice runabout, its on White Bear Lake now. But old picts I've seen they have had a tri hull and a V174 for sure.
Her other sisters are looking for them as well, I'd like to convice them to by mine so I can buy something with "CV" in the title.
