the reason for a step in a seaplane float is to control the position of the centre of pressure of the float relative to the centre of lift of the...
Just to add to the above posts. When looking at a hull, a simple check for hull type is as follows. Look at the profile(side view) of the keel...
Welding over old welds is not a good idea. The metal will lose strength on possibly crack. Try and get some info from experience alum welders....
From what I have seen the new electronic marine diesels are incredibly fuel efficient, whereas the old mechanical governed motors drink fuel....
If this is a factory produced boat then I would assume that it planed properly when it was built. 1. Check with the builder if you have the...
The big thing to look at is: Is the boat tied up in a marina or taken out of the water . If the boat lives on a trailer, then it does not matter....
The 1500hp was the BMW qualifying engine that lasted exactly one lap. In race trim the turbo engines got about 800hp reliably. You could turn up...
The only advantage of a transom bracket is better steering. This arrangement looks cool but is not worth the effort if the boat behaves well...
Talk to your local us coastguard station and find out about the situations they have seen. They will give you a list of what they would like to...
My colleque and I have done a few boats using Dr Hoppe's foil system and they definitely work. You do have to do a costing as to what is...
The main down side of this system is that it protrudes below the hull and a keels or skegs have to be built arround it to protect it. In south...
backfiring is usually a sign of retarded ignition timing.
Check the transom /bottom junction. IE do you have a sharp edge, or is it slightly rounded. For a planing boat the bottom edge of the transom must...
Have you tried Hullform9. I have produced several hardchined hulls. To produce drawings of existing moulds. Hullform does not work with surfaces....
This is probably a broaching tendency or 'bow steering'. This is usually caused by the centre of mass being too far forward, ie the boat will...
choose a flat bottomed monohull with a big outboard engine. This is good for glass flat water, though the first wave will knock your teeth out.
Thanks for the comment. The reason, I went for catia, is that I burned my fingers with adsk Inventor. Solid works seemed nice, but the fear was...
I am just starting out with catia v5r13 P2 for boat design. I use Hullform9 for lines generation, and then 3d dxf the lines into autcad. I then...
