Yacht hull design?

[Brian d marge]

OK this is a long shot, but hey nz city of sails, someone on here must be interested
Im bored, the stuff on the bench is just straightforward builds, and i want to use my CFD skills more
so I cleaning out the boys old toy box and I've got lots of old RC, car parts,, u know 4 year old, dukes of hazard, Chinese RC car bites the dust
so I was thinking, I could use my CFD and rapid prototyping skills and make ( from first principles) an RC yacht.
I know a little about waves off the hulls of ships, but that's about it
any ideas anyone?

thanks in advance
Stephen

My old man had an RC yacht... they used to "race" them down at the local basin, beer and sailing from the safety of a chair, bloody good fun... although his was built from a kit. Good luck.

This may give you some ideas

These are pretty simple to sail, they have 2 controls, 1 for the sail trim and 1 for the rudder.

Through the 60's and 70's the model yacht fratenity had the most radical monohull designs.

there were and probably still are several classes with well defined design parameters.

i don't know where you'd find them on the net but they must still be going.

If John Britten could be named as a potential Americas Cup designer, how much further can you get with actual CFD gear available ?

if it floats, its all good from there
CFD bit of a learning curve, still cocking things up, but the idea I had was to print out the hull using , 3d printer, ( as i pay for the volume of material)

nothing complicated, just trial a few designs on the computer, print out one and see if it floats

keep the old grey cells going!!

thank all,

according to my Dad, the bastard was getting the boat balanced correctly. He fooked about with the thing quite a bit with differing results. My Step Dad said similar and he was building 6ft tanker replicas (probably pissed off that he couldn't balance them in the bath and had to go the local lake, heh even then a bit of a mish to get them into the car)... they were something else as he used to make a lot of his own components.

Ok off and running, interesting reading , and I think even the printer can handle a 1 to two foot hull, must have 3mm wall thickness

Having a look at the thing in Auckland it looks like a "planing hull" , so I try and copy that

see how we go

ta for input
