considering i'm 78 pounds. And gases are compressible... you have to figure out how compressed you can get it per meter cubed, and figure out how much that gas weighs in total. Take the lifting force of gas per meter cubed and subtract gas weight and hull, spars and sailor weight = how much boat could potentaily weigh. Thats just my guess at a way to figure that stuff out. equation is as follows(in my opinion):
modifiedweight = ((gas per cubic meter x volume of hull) x lifting power of helium per cubic meter density) - (sailor weight+ spars + gear + sails) =modified weight
theory= displacment(in pounds) - modified weight
^^ not acurate im just guessing and throwing stuff
If you are 78 pounds you are plenty light already.considering i'm 78 pounds. And gases are compressible...
Compressing the gas would just add weight.Thats a good point. What if you injected helium into your top section spar and compressed it and sealed it? Would that not have the same effect but not on same scale?
April Fools. You've already had a rocket scientist in this thread indicate that it won't work.The mast section is too heavy to be affected by the amount of helium that you could get into it. Do you see the tank of compressed helium at the balloon store trying to float away? You can't achieve the necessary neutral buoyancy.No want im getting at here is that would it help them stay up right? Plus i don't understand 3 months and 1 day early.
Forget Helium...i'm working on removing all the Higg's Bosons from my boat....

Agreed.I had a good chuckle all the way through this thread...the only scary thing is that the OP appears to be serious about wanting to do this......

Agreed.
I do wish sometimes people read the fundamental rule, which essentially says that everything you think of to change your laser whether it makes it faster or not, is illegal unless there is a specific rule that says you can make that change. Anyway, even if you did fill your Laser with helium, it wouldn't impact on the buoyancy as the volume of the boat is bugger all and anyone who saw the Myth Buster’s episode would be aware that a huge amount of helium is required to left a person, only probably 20% heavier than a laser.
Next on LaserBusters:
- Is the Intensity Sail actually faster than the class sail?
- How heavy is too heavy for a Radial?
- And can you really kick all the water out from the bottom of the cockpit?
