Thanks - but unfortunately the dual rudders are not feasible for the hull design, also a problem for debris in the shallow canals. 20% was my...
Many thanks for your thoughts - all understood. So I can move the pivot point forward but only at the expense of full deflection performance. Our...
Good evening all - & season's greetings. I noted that a 40% chord pivot point is often quoted for a Schilling profiled rudder blade, and this...
Thank you Leo - that's amazingly good advice! Unfortunately you have to comprehend the maths first, then you see how chaotic the environment is ie...
Thanks Leo, the PhD level is a little intimidating, but I'll give it a go :)
Thanks Jurgen - I've sketched similar myself. For the refined model the aft swim profile is more open which must be beneficial for the propellor,...
Thank you David, sound advice! I've already stepped on a couple of those minefields, sometimes it's two forward, one back - but the learning...
I couldn't tell you verbatim as I don't have comparable surveys, but idle chatter amongst the community online would suggest it's a common issue,...
I'm not studying in the formal sense or as part of a structured course - I have the possibility to influence the hull shape of a new build...
Forgive me, no doubt a dumb question but... If these waves are present sub-surface and are of significance to my calculations, why do you not...
Many thanks David - Yes, most definitely a school project in the sense of being a naive but curious student! No, I haven't studied the wave...
(thank you) - OK, which equation would you use in this situation?
For sure - thanks for your interest. This is the site of a respected builder of traditional working narrowboat replicas, amongst many other...
Gentlemen good morning - help! I'm considering design factors for UK canal narrow boats in confined channels. I've been privileged to enjoy...
