Gonzo: "The short hulls will have more drag than longer ones" I think Dejay made a good first stab at this .. Once hulls get to a L/b of about...
Oh geez Ad Hoc … now you’re really challenging my old brain ;( .... but let me see what I can remember. It would be easy to just say this is...
Fandango: "...as one of the blokes on SA said, the main beams should be taking most of the load". I've not read the SA posts but not sure I can...
Fandango PS, unrelated but I'd be really interested in W17 designer's opinion on camber on amas/floats at some stage. Rather than invade this...
Ad Hoc: Your second statement is not correct. The power (thrust) required to push a hull has many inputs and it not solely sqrt of the length Ad...
A far more modest electric boat could be created based on this design FLAIR by friend and fellow Canadian, Laurie McGowan, created for the...
I am sure you have noticed this by now, but sailing catamarans typically have a range of B/L of 0.4 to 0.6, whereas sailing trimarans are...
Although trailers are often responsible for damage to main hull bottoms when rollers are used instead of bunk boards, I rather doubt this is the...
Seems that Fandango has understood your arrangement better than I ;) Would you have a photo looking from forward back on to the folding system...
First thing you need to clarify is whether this is a proposed sailing trimaran or a motor tri. You also mention 'pondering catamarans' in your...
Sorry SD, but I personally think the compromises you suggest are just too great. Who would want to risk good sails as a tent or use an efficient...
I used to think like that too SD. But over the years, be warned that 'the magic' will disappear as most 'multi-functional' tools end up by doing...
Dolfiman sent this: May be one can add this one here below ( of the steamer Ss Delphine) to your typology, combining a reverse bow for the lower...
I would like to see a video of this 100ft boat (with foils) sailing and pitching in 3m waves @ 30kts ... before the ama bow broke off of course ;)...
Sorry Doug ... I should have checked the length ...I had just auto-assumed 17 was for 17m ;-) This would however make my point about 'relative...
As the 'Squidly-Diddly' do-it-all boat with sliding seats etc. is a far cry from the original, inexpensive open fishing boat sought by the...
Just to note that I agree with Doug that adding foils can certainly help control pitch and there's a note to that effect in my 2013/4 articles....
Thanks and glad it was helpful. The SAIL article was tweaked from an earlier one I wrote in 2013 and personally, I always found the original more...
Great idea ..but I think it would be helpful to all who may want to help if you could collect and post some photos of the types of boats presently...
Maybe a little late to comment on this thread, but when I look back to Pitbull’s original post (OP) and the comments that followed, I could not...
