I am in Minnesota. I have been looking at used boats sales ads, (outboard, fishing boat about 18' to 20'). Some ads say Utility Hull, some say Deep V, etc... I kind of know what a deep V haul is. I am not sure I know what they mean by Utility Hull.
A deep V is a deep V reguardless of where you are boating.
A deep V is well suited for rougher water as it cuts the waves/chop. The deeper the V the more low speed wonder you will have. A utility is a compromise between the chop cutting of a deep V and the lateral stability of a shallow v or a tri hull.
Maybe it's a regional thing; I have never heard of a "utility" hull. I had thoughts of the flat scow worker boats I see around dredges, shipyards, etc.
