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...
Bravo! I'm afraid that's exactly what started my mind ticking in the first place!!!
Yes, a narrow beam canal boat. The internal length is around 48ft, our overall length limited by lock sizes on various UK canals. Because they are...
Thanks David, what distance between fore and aft rollers to ensure the wall stayed vertical? I'd prefer it to hang as you suggest and avoid any...
There's a video here of an apartment, a "transformer" style with a moving wall, from 3:20ish... My wall would be a traverse bulkhead with a...
I'm afraid I haven't worked that out... it will be hollow (stud wall I guess), ply skinned with cubby hole shelving on alternate sides... Noting...
Hi Guys... Help! Google has come up empty. I'm looking for prototypes for a moving dividing wall. The project is for a narrowboat with typical...
