speed boat design

Both!
I prefer the right but a 3-D view would help in deciding.

 

Rc model 1:10

It run very well, i tested today, tomorow more test

 

Some progress of fullsize

 

Sea trial, model 1:10

 

She is going along very nicely, without much wake, relatively.
If it is possible for you to slow the video down, then you will get a more accurate portrayal of what the motions of the full size boat will be like.

 

thank you for your reply, i will do more video with better quality

 

some update on my new build

Are you intending to paint the boat?
If so, those welding impressions when painted will show up dramatically.
They need to be SANDED not ground to get rid of them for a good finish
When sanded, run your fingers over the sanded area, if you cannot feel any irregularities then it will paint over smoothly
The sanding discs with the holes in them, so you can "see through" the disc, are the best way to sand.
As the weld print through seems to be quite strong, there will more than likely be a difference in angle above and below the imprint. So you will not get all the inflection out, but better than leaving it.
Take a felt pen, run down the center of the bump, then draw in increments of say 3 lines ( one per inch) above and below the center. When sanding keep the area where the material is coming off on, along each line.
After this is done, take a soft backed orbital and finish

I expect your 15 degree V will be hard riding in even 2 foot waves and the plumb bow will throw water over the front at waves over a couple of feet.
I owned one of these for one year, if you were going upwind, the plumb bow shot water over the bow, and the wind threw it on the windshield .

 

Bajansailor mentioned slowing the video, you can do this directly in youtube by clicking "settings" just under the video; I've just watched at half speed, looks very realistic.
EDIT Not just under, just within the bottom of the video.

 

thank you for the reply, actualy it will be filed with filler and sended then painted

 

barry , what type of boat was, that you owned?

It was a 29 Ranger Tug, that picture is not mine as this shows the boat with an outboard. Ours was an inboard. The word Tug is misleading as the boat was a monohull designed to plane. Not a displacement hull. We cruised it at 22 knots, 2 miles per US gallon
I could not find the spec on the deadrise but I suspect that it was between 16 and 20 at the outside. Ie relatively flat.
Nicely finished, got rid of it as it was only a single engine, incredibly wet in moderate seas.
