I'm assuming the 5000 lbs (2.27 tonnes) displacement specified for the Oldport is with the standard diesel power. It does differ markedly from...
...though actually, it shouldn't matter whether it's ft/(cubic feet)^(1/3) or meters/(cubic meters)^(1/3), as long as there's consistency,...

From Oldport 26 Launches https://www.oldportmarine.com/oldport-26-launches.html: The basic dimensions of the Oldport 26 have remained the same...
Thank you, Dave. The Atkin I referenced is Rescue Minor, but Spermaceti is indeed interesting as it represents a longer, narrower and presumably...
I have also presented a graph, at post #146. The graph you presented is a representation of a set of data from a set of tests designed to isolate...
I don't wish to participate in your quiz, AdHoc. If you want to state your point-of-view, as such, I promise I'll consider it seriously.
AdHoc, perhaps it is true that I should thank you for this graph. Thank you. [IMG] You know what does occur to me: the Freedom Class Littoral...
Thank you, Dave; I found https://www.ericwsponberg.com/wp-content/uploads/2021/09/THE-DESIGN-RATIOS.pdf a very useful reference. Jurgen, on page...
It's velocity dependent. If by a canoe hull you mean that there's no transom, there's theory that says it's midship at displacement speed....
You persist in addressing me as though I'm Young Naive Inexperienced , AdHoc. I'm none of those things. If I've said something you don't agree...
Apparently Irens' 12m (39ft) version was referred to as "RANGEBOAT". This explanation appears at Hull Design for Propulsion in Small Craft - Clara...
Once my current small boat project is finalized, I'll pursue this as HJS suggests in Projects & Proposals...
What preconceived notion / misconception, AdHoc; you're trash talking without the guts to be specific. You're also saying I've rejected something....
So... You agree that that a 10K lb weight vessel will change resistance if you... 1) Change the L/D ratio...noting that the L/volume^1/3 is not...
It's you who are talking in circles, Jehardiman, and it's sad that you don't see it. If you think I've opined about something not factual, cite...
I've said plenty of things of substance, and you're free to agree or disagree, AdHoc. No question displacement to length ratio is probably the...
I can't tell from the photo above, but what I'm proposing is essentially to combine the stern of the windsurfer in your post #3 with a narrow...
So you're trying to tell me two boats with the same displacement/length ratio will in all cases have the same resistance, that hull form,...
