Kayak Flotation, how much do I really need?
This is the BWE Don't Over-Think It But If You're Going To Do It At Least Do It Right version.
How much foam would Harry need? 90 lbs / 64 lbs per c.f. = 1.41 cubic feet of foam. How many milk jugs of foam would Jorge need? 1 gallon = .134 c.f., so 1.41 / .134 = 10.52 milk jugs. How many ping pong balls would Myth Busters need? 1 ping pong ball = .0012 c.f., so 1.41 / .0012 = 1175 ping pong balls. How many pool noodles would I need? Mine are 2-1/2" round x 55" long with a 7/8" hole down the middle. 1 noodle = .137 c.f., so 1.41 / .137 = 10.29 noodles. Each of my noodles provide 8.768 lbs of buoyancy in saltwater (64 * .137). These numbers are for neutral buoyancy, i.e. it won't float to the surface (ignoring Archimedes' principle). Add more flotation so you have positive buoyancy. A foam mfg. guide I read recommended 2:1 for a safety margin. I would use 10 of my noodles and rely on the factory installed foam blocks in my PA as my extra flotation. Place your flotation in your hull high and to the sides for submerged stability. Place 50% of your flotation fore and 50% aft of your rigs center of gravity so that it will float level while submerged. Level floating allows you to access your safety gear, allows you to get on top of your submerged rig, and at least gives you a shot at bailing water out. You don't want to have to swim away from the Titanic. If you want to over-think it you could start with the Flotation Requirements sections of the USCG Boatbuilder's Handbook. |
I'd rather lose my kayak than try to stuff 10 noodles inside.

Where the hell am I going to find a .52 gallon milk jug?

Many of us have too much time on our hands.
Good info...but I'm gonna take less stuff out on the water. |

this could be useful information for some. I had to save a kayaker and his son 2 weeks ago in san pedro when their kayak was completely water-logged. good thing they had PFDs and the guy had his stuff strapped and tied together. even his phone and wallet were okay.

Hey Paul, I should of thought about this better, i only had 5 noodles in my kayak, going to 99 center later |
Who has room for pool noodles when that space should be used for extra beer & ice!
You guys have it all wrong.:rolleyes: Have PFD, VHF & hand pump... I'd sink the yak too. Cheers. :cheers1: |

I haven't tested mine fully waterlogged but my guess is it prob wont be paddle able but will provide better vis for rescue, and keep it from going down with gear, and the kitchen sink I always bring don't forget the swim fins ... I like the example of the whale pump mounted externally When you need to pump out from the hatch, its also the place where water wants to get in. The last thing I want to do in choppy waters is mess around with my hatch open. |
