Delftship == Freeship ???
call me cynical, but shouldnt the poll be more like "how many users are there of the following software on Boatdesign.net" How many voters have...
hi Leo -- just wondering, when you are dealing with calculation of the wave pattern, how do you deal with transom closure? Or do you leave it open...
At the end of the day we need to provide practical solutions to ship designers otherwise we wouldnt get funded. The form factor is a nothing more...
Oh I now see where the differences lie -- you are dividing by running WSA -- all the coefficients Ive published are based on static WSA, which for...
but what is "Michlet less viscous" -- it doesnt look like (Rt-Rv) / (0.5 rho S v^2) given that Rv = Rf since you not seem to be applying a form...
PS I added 10% error bars -- since apparently experiments are so unreliable and the data is not to be trusted (despite the fact that the Wolfson...
It looks like you are comparing with the the Cw from experiment (the filled dots in Figure 2) which is Cw = Ct - (1+k) Cf with Cf from the...
yeah sorry vertical axis is incorrectly labelled Ct -- should just be resistance coefficient. Its essentially Cwp -- ie wave pattern resistance...
lest keep on subject? personally I cannot think of anything worse. Riding a bike on the flat is bad enough. Cycling on a lake must be like...
the models I tested in 91-96 were NPL-round bilge. I think some of the later work by Taunton may have been Series 64. But they are pretty similar....
some unpracticed oarsmen trying to row a reconstruction of an Egyptian vessel from 1500BCE (about 15 tonnes)...
oops -- yeah that would be kg
possible, but the tank was 3.6m wide and at the wides spacing the catamaran hulls were CL / CL 0.8m So dist from CL one demihull to tankside...
just a bit of a note on the experiments we did almost 20 years ago! Given the underlying assumptions (linear, potential flow, thin ship,...
hi Leo -- Im pleased you liked the paper can you read an IGEs NURBS file or do you prefer sections (if so how many is ideal)
Sail like an Egyptian pushing the limits -- as a matter of interest I tried using hullspeed to estimate the resistance of an encient egyptian...
hi Leo -- Good to hear from you, happy new year hope all is well! doesnt slender = thin (just more polite :-) I must admit that I rarely have much...
attachemnt -- I hope apparently there should be an attached file?
hi -- I was asked to reply to this forum. I am patrick couser, I studied at the University of Southampton under Dr AF Molland where I continued...
