This isn't another rant about which type is better just trying to gain the fullest understanding of
Here is another comparison of a hull form at speed. This proa deffinately has a different motion to it due to its type of proa most likely but hull looks as though it not working very hard even at speeds of 23knots.

Though to me just an observation , cant feel what the boat is doing , just looks like the leeward hull seems to be tring to hard going through the water. Is it topping out in its max speed potential for hull form or can the hull be pushed harder above 15knots with out any ill effect just more spray. I'm not one to worry much about spray as long as I'm not standing in the direct path of a fire hydrant!

With the latest modifications, reinforcing the original rudder sleeves by Rudolf and Nol to replace the original rudders and removing these second generation rudders by Nol and me, BD is now reborn and healthy again.
