Ok. this is exactly the same result i got but I simply use the SCALE cubed for the multiplyer ... notice (12/3.375)^3 = 44.94924556 (44.95)
I'm cubing your 1' : 3.375" to get my numbers for real life weight. ie: 3.375^3 * 3.8pounds(main hull of model) = 146.0847656 pounds for the...
Sorry Doug, I went back and am having a good look at the numbers now. I am trying to compare with my project is all ... love your work
So roughly 146 pounds (real life) for the main hull and 642 pounds all up(inc ballast) It's amazing how fast these models gain weight :(
How much does the model weigh at this point and how long is it ? How about the weight of th emain hull alone ? What is the scale ? (I'm too lazy...
model cat Now THAT'S fun ! I suppose the hulls are much like your "B" hulls from above. L/B ~ 14:1
model cat Giving it a try ... Hmmm, looks like it's gonna work ;) Thanx for the info :)
Models Merry Christmas too you also ... Working on a model also at this end but curved lifting foils are not an option for me right now ;)...
:)) ... Probably for a basketball player. I had in mind 3.5' with the fulcrum @ midpoint on the lower hull, so 7.5'... Total being 11... Ray,...
Not sure where you get teh 5:1, The Lewmar blocks I bought not too long ago have written on them... SWL(Service working load) = X (pick a...
Hi Doug. rough calcs : 2 x 170 x 11'(rough CofG for crew about fulcrum)=3740ft.lb for crew alone on a N5.2 ... Well, this is what I get anyway....
You're right, but there i s always a little more to it. Ahmmm, I had to edit my previous post :(. The column loads on a multihull's mast at...
Well, truth be told, "column" loading will be the same regardless of BOA(roughly the weight of the boat) providing chainplates are set on the...
;) I had a feeling you were thinking of it along these lines ... Let's take your example, and now figure out the loads needed to fly a hull ;) You...
Ahmmm... 2 things 1-Diamonds to me = spreaders so 2 thumbs up 2-Wider beam generaly means higher compressive forces on a mast. A N5.2(at 8'...
Does the 5.2 rig have spreaders ? It's been a while but I believe it doesn't. I'm not sure what you are putting this rig on but if it(your boat)...
Scarf... Take the time and do it right, that way you have nothing to regret later. Scarfing is easy enough and quite fast when using a jig. ie:...
