If you're only talking "flatbottom v-drives" the 19' Family Ski was very common. I heard from someone who worked at Sundown Marine there was a 19 runnerbottom also but it was a prototype.
Yes I'm talking about a flatbottom,( not runner bottom), v-drive. After reading about the "Gull Wing" bottoms on the PB forum I wondered if there was more than one bottom type on them. A friend of mine has a 75 19' and he is having some handling problems. I had a 72 and a 74 back in the day and mine handled good , but I can't remember exactly what the bottom shape was. It seems to me that Sanger said put a little "gull" shape in the cav plates,but I can't remember the bottom having the "gull" shape.
