Bowsprit length is not proportional to notional hull size. Dimensions of boats are notoriously difficult to define unless you have the designer/builder original drawings. Even then it is no guarantee they were built exactly to the drawings, nor that all boats of a class were built the same. The only fool proof way of knowing is to measure the actual boat you are interested in. In reality the exact overall length is only relevant in a small number of situations, for exmple for certain marina berths or for shipping when usually any published data is ignored and actual measurements used.
Actually, those on the list are completely different designs, they just used the same stock drawing (of a Tashiba 36) as an illustration, regardless of the actual boat. Most of them have canoe sterns, but the Cape George 36 has a transom stern, while the Panda 38 has a counter stern; the Cape George and the Tayana both have a full keel with no cutaway forward, while the Crealock 37 and the Alajuela both have a fin and skeg profile. That said, the Baba 40, Tashiba 40 and Panda 40 do indeed share the same hull.
We've tried to contact Robert Perry before through various means with other questions, without success.
