boats that are designed with car aerodynamic method?

loose steering
rubber mounted engines
drive too deep
planning surface to small
bad weight distribution
Some boats will at certain speed you just drive through it
its a lift drag torque thing

 

Thats the kind of answers we need more of !!

Steering push pull cables with slack is quite common .
keel pads and the boat gets up and up and falls off ballance and can barrel roll after the chine walk . scary!!
Watched a race boat chine walk everytime he went out same thing all day never got it right at all !!

 

We're doing well, thanks...still some neighbors with piers to repair and sunken boats to haul up but nothing like the poor folks farther north up the coast.

I was drug in the original Air Ride "SES" project at the behest of the owners. However, all I could do was perform last rites and declare it dead on arrival; nothing could be done to "fix" those things. I managed to avoid being associated with any others like that until the boys at Wavemaster caught the fever and built their version of a "twin-cavity catamaran". The trials program was ...uh.."short". They managed to escape too much embarassment by hauling the vessel, removing the blower system, and putting shell and frames over the cavities to convert it back in to a conventional cat; said conventional cat a good 3-4 knots faster than when in air cavity form.

 

Testing by the ONR had shown the vessel was capable of 80+ knots, and it was highly stable and efficient even taking into account the additional power required for the blowers.

 

Hi,
Not exactly off topic, but a little bit border line question, so I apolgize in advance:
Any suggestions for a freeware to address the aerodynamics of car??
Thkx & Cheers
