23' hull design

[gumbolimbo]

can anyone tell me if the 23' hull design has remained the same over the production span ? I have seen this subject referred to on this site , however I was more curious about the possibility of a defintive answer. It's interesting that differant 23's can have such differant appearances. also--- is it fact that the tsunami 23 and the sceptre 23 are essentially the same ? Thankyou this is my first communication on this site and thrilled to have found it !!!
