Design What principle do you apply to lift the bottom in this scenario ? The outriggers have more strain to endure when you are on a wave...
Open ocean concerns Rick, we have discussed the design in its current stage with regards to Hawaiian open ocean conditions. Two points of...
developments Rick, There is actually a way of using a delftship file in freeship; it is probably not intended use, so I will hold on posting...
FreeShip can't read DelftShip files; DelftShip free does not allow to save the plates. I will try to reengineer the HC hull in FreeShip so...
The layers and plate development are working now. I think that the free version of DelftShip does not allow to save the developed plates. Is...
outrigger Rick, my current outriggers have a flat bottom that rises towards the bow; they are not piercing at all. We try to get them on top...
isolated plates The plates have been isolated, see attachment. I think I can load them individually and save them from the lifeplan view. I...
ship_ouput_speed NC 7.28 Rick, I do not have the Excel spreadsheet, so for me it is a little hard to read.
HC hull The HC idea is the better approach, you are right. Do you expect the HC hull to behave more or less alike to the NC hull, especially...
Michlet run NC - 7.28 m Attached is the out file for the 7.28 m hull, derived from the NC. The hull lools reasonably clean in shaded and...
Michlet run HC hull This is the 'out' file from the Michlet run. I will run the NC and post that out file for comparison. The limitation...
Construction Rick, meanwhile I had a chance to open the file in DelftShip; the boat looks nice. My file was made with FreeShip plus 2.9 -...
First attempt I think that I will stick with a round hull. I like the idea of flat chines in the forship , but I rather add them in case they...
Design details Rick, thank you very much. To have the ama ride on the bow wave is a very good consideration, I never heard about it. Great....
Linesplan The linesplan at 5 m/s has less rocker. Waterline length 7.28, beam 0.255, draft 0.105. KAPER did not work in Freeship, not sure...
Construction Some specs for those that are following this thread: Hull: from outside to inside: carbon - thin core - carbon - thin core -...
Linesplan The current design - 7.90 m, beam 0.25, draft 0.11 - under water body requires about 12 % more power at speeds up to 5 m/s. About 22...
Rick, thank you for the file and suggestions. Indeed, we are trying to paddle the OC like a surfski, rigging the ama as light as possible....
Thank you very much. I suppose it is the formula in the following article that can be used: http://en.wikipedia.org/wiki/Air_resistance...
DelftShip Thank you, Rick I have read this advice from you here on the forum before and have been trying to go back and forth between...
