I suppose I should know better than make comments like that around you lot! - What I MEANT to say was that the hull will behave more like any other hull in so far as that it will require less effort and concentration the slower you go!
The leisure boat will have the same hard nose as that is part of the "look" of the boat. As I said on another thread hard boats have managed quite well for many years without tubes around the bow. The fact is that if you look at the design of the BananaShark, you will see that an inflatable nose would make no differance as to the seakeeping at all, and whilst some ribs are designed with the soft nose as part of the boat, the BananaShark was not and stands as she is at any speed.
To try and cut a long story short(er) some ribs COULD have tapered tubes or small hard noses like the BananaShark but not all - whilst I would love to give examples of this I'm sure there must be owners of boats out there who wish they had a bigger nose!
Sorry for rambling and I hope all the above makes sense!
