How deep do skis sink?

No tray stays perfectly water tight forever if the ski is used to it's potential. Polystyrene will at least keep the tray from getting completely full of water and make the ski heavy while riding it.

I'm sure someone here that is smarter than me can make an inflatable bladder and air tank that is depth sensitive to like 15' that would go off, inflate and bring the ski to the surface.

That's what I've been thinking since I started skiing. Stick it in the fire extingisher hole or something along those lines.

Krenn the way I figured : 1 cuft. h2o =7.48 gal, h2o=8.33#'s per gal. 7.48 x 8.33= 62.3 #'s per cuft. 2.5cuft x 62.3#'s=155.75#'s. if ski weighs 250 aren't you still 95#'s positive ?

No, because you aren’t taking the buoyancy values of the materials used in the construction of the ski. 250lbs above water isn’t 250lbs in water. Each material has a different weight in water. You have to look up those weights and work with those numbers. For example. If you had a block of carbon fiber that was 250lbs vs a block of steel that weighs 250lbs the carbon would be much more buoyant than the metal because of the density. The more dense the heavier under water. The less dense the more flotation it inherently has. So as your formula is 1/2 correct you’ve figured out the density of wate, you have to figure out density of all the materials used in a specific ski which takes some guessing and weighing parts while ski is apart.

a super easy example is a person that weighs 150-200lbs is only 10-15lbs under water. Life jackets are rated at 7-20lbs of flotation normally.

Neutral flotation scares me if the ski gets away from you.lf you can hold on to it great.But l have been preaching this not adding flotation thing for years.Mostly building smaller afternarket skis,there just isn’t enough areas to put flotation unless you @McDog it.Pool noodles everywhere!
l would rather let that bitch sink straight down.But in some cases like Dylan’s it is not such a good idea.lt’s just a risk we all take with a a/m ski.

Let the debate and math formula carry on.

As someone that lost a ski and cost him $3000 to find it plus dive gear rental and the 3 days of stress. I’d rather take the chance of it floating around because whom ever is riding it would have the chance to not lose it if it is light. Mine went down because they couldn’t hold the weight

A year later and I never found it. On a lake. Put out a 3000 dollar reward for anyone to locate it but I’m having a bad feeling it was found and stolen. If anyone comes across a white/yellow bottom deck EME for sale or my one off 10 vein stainless mag pump on any forums/marketplace I sure would love the closure. Thanks fellas.

Damn, this is exciting. Cant wait to see it, please post lots of pictures! Also let us know how you found it and what it was like to find it.

The ROV operator that I spoke to for over a year went out today without telling me and just called me and told me he found it out of the blue lol.
i will be there when they pull it up to the surface.
I’ve already been through all the stages of grief so at this point I’m not sure how to feel LOL.

As of now the fish and game commission won’t let me bring it home until they “decide what they want to do with it” on Monday.
i have no clue why they have to “inspect the ski” outside of them trying to find some reason to give me more fines than I’ve already paid. Ski will be hoisted tomorrow and I’ll be trying my best to preserve what I can before it sits in open air for god knows how long. Going to be reading about recovery laws and such in PA and hopefully they don’t try to shaft me more than they already have.

My EME I had would sink like a rock, and I mean literally like a rock. Tore off two scupper flaps and both times by the time I realized what was happening it had water over the carbs and was going down like a brick. My buddies Arial 8 was the same way. I would spend most of your time looking where it went down.

You were spot on man lol
