Echuca paddle steamers

[anth]

G'day all
              As some of you know I am building a paddle boat......well a friend rang me up and invited my wife and I up to echuca to spend a few days on his paddle boat.
Did I learn a lot aout hull design if any of you have looked at the aussie paddle boats you will know they have a flat bottom for less draft.....what isn't publiszed is how many are unstable and especially in strong winds and when they lean the paddle wheel deepest in the learn try's flip the boat......this worried me when i was able to nearly flip a 36 ft with 2 people rocking it and the same effort rocked a 60 ft boat.....
After talking to a heap of owner's and hearing the story's a change must be made.....
so it backed to the drawing board..!
Does anyone have any pictures or drawings of a v style hull with min draft
it must be a sidewheeler
I would love to hear from others about this.....?
                                                                   Cheers Anthony

Hi PD's - sorry Anthony, it is not a deeper V hull that will help you but more a lower C of G or metacentric point of balance & less windage effect

We ventured over to Mannum in 2002 & saw some beautiful pontoon style river boats under construction, but they are just large air conditioned SHOE BOX's and when the wind hits

Our earlier forebears publications & tales remind us that lake Alexandria provides a nasty chop & sufficient to overturn even paddlers - Derek

Thanks derek,
                      I understand the center gravity has a major influence but the reason for a V hull was that a multi chine hull behave's much better.
we had three people standing on the paddle box of a 47 ft paddle boat and it didn't seem to lean but the same test's done to other boats showed a disturbing result.....regardless of hull design the boiler will still take up the same space but i figured with more hull in the water and 3 chine designed hull which alot of new paddlers have I might end up with a better performing hull.
The model hull i designed was extremely stable but it's real life cousins...well not so good....
                                  Thanks for your help derek any further info would be appreciated ...
                            Cheers Anhony
