I have been thinking about the same since I visited Ono. The most important thought goes like this: "If I ever get enough money and time to start the visionarry project I must take my wife to visit Ono. How am I going to get her to accept the idea of this kind of boat if going to the boat requires walking on the bow like that."

 

I fully understand and appreciate the idea of a bow that sheds the water from the top fast and effectively but walking on those bows requires an acrobat and flat water. And since here in the Baltic Sea the boats are usually docked bow to the dock this is a daily issue when cruising. Redesigning those bows to become easier to walk on for docking, fenders etc. would probably make harryproas easier to sell to families.

Subject: [harryproa] sloping vs flat high vs flat low

 

In the cruiser HP the top of the lee hull slopes up from the low bow to over the beam attach point. I assume this part of the internal volume is not very useful. In the 18m Melbourne this part is flat resulting in a high bow. This is easier to walk on than the horse riding moves needed to manage the bow fenders like on BD. In catamarans this is generally flat too resulting also in high bows. The extra volume is used for light weight storage.

What about assembling a lee hull with "proximal" bows as high as and as short as on the ww hull but extending them in the lower halves straight out resulting in a flat top at "distal" low bow height. The volume/material saved from the lack of sloping top could be used to lengthen the hull proportionally even more. I guess a sloping hull would be stronger for the same amount of material. Other disadvantages I overlook?

Thanks. Luc
