Wave interference boat 2.0 Hi guys! After years on working on the super small "wave interference" boat the design completly changed to something...
Hi guys! I have been working on the idea on how to create a super-small but fast boat for years. Finally and with the help of a guy from Swiss,...
@ Gilteva: There are already "raked" propellers for planes. The problem is, that centrifugal forces require a straight blade. If rake is...
Hello Mike! It is designed as an "stabilized monohull", like an evolution to Rick Willoughby´s work, but you can theoretically use two of them...
Hello Mike! I also checked for that form too. I ran Godzilla in order to look for promising forms with the constraint of being a relatively...
For no wake, look here: http://www.openwaterbike.com/projects/the-open-wavewaterbike-project/the-wave-interference-hull and here:...
It looks like an olympic rowing shell with the tail cut off. Actually a 7.8m parabolic hull cut down to 6.2m seems to be the new benchmark: 350W...
Hi guys! I didn´t spend much time in the forum for the last months, but I got really interesting news. After spending weeks in studying...
OK, I have to revise my statement after seeing the picture. The prop has around 90% efficiency and is fully submerged. It is a 16" RC prop,...
I have also experimented with a belt drive, but I am using a two staged gearing at the moment, as the maximum ratio you can get with one stage is...
Thanks Coach Dave! My plan is a modular drive system. The first module would be a two stage gear with a HTD belt 100:22 and a second stage with...
Question to everyone I would like to build a shaft drive going through the hull, but there are two parameters I don´t have the expertise how to...
@jdrower: The Lakerunner was surely one of the best HPB, but Yamaha decided after building 5 prototypes not to go into production.
@ Gib: That looks just like my latest design without weed shedding. My tests showed an efficiency of 82% for such a design, which is really good....
