Hydro 21 from Japan

Jorgen, thanks for posting the Japan hydro. What construction materials are used? What props does the hydro like? Thanks, Richard D

Nice lookin boat Japan style boat.. Different thinking in fin setup ?

Hello Richard

This is an all wood boat with Divinycell core for the sponsons.

During my testing, it likes similar props that the more common boat likes, BUT it likes less lift and slightly larger diameter.

The long afterplane gives very good stabilty and it is just fantastic i rough water, by far the best I have ever seen.

Yes, the design looks really good. The fin is different to what I am used to and seems to be an even more important factor that it has been on traditional boats for me. I did test 4 new turn fins during the weekend, 3 is in the scrap metal box, but the last one was really promising, more to come out of this.
