somebody know about the 35 commander hull type,,like deep-v or modified -v..ect..google doesn't help me..
It is a modified vee, look at this picture from the 38 owners manual of the boat in slings, same for all the 13' beam models.
Chapter 2 page 43
I’d describe it as featuring “...two longitudinal planing strakes as well as an attractive, molded in, circumferential spray rail (hull side foils). The boat had a full length keel with modified deep V gullwing planing surface. It had a distinctive V transom design which was borrowed from Chris Craft's World War II landing craft. This design was intended to improve the craft's handling characteristics in a following sea.”
