Re: Ford F-350 vs. Erie Canal (Fairport NY)
submerged vehicles are heavy, but 5-6 times? thats a LITTLE excessive... Your average 1/2 ton truck, 5000 pounds, coming out at 25000 to 30000 pounds would pretty much destroy the entire truck instantly. (thats 2500+ gallons of water!)
Yes..
A cubic foot of water is 62.4 pounds
Take any vehicle..I will use a Ford Expidition. According to Ford's website, the Expidition has 108 cubic feet of CARGO SPACE (which doesnt include the cubic feet of the foam seats, headliner, door pannels, door cavities, consoles ETC ETC)
So just the cargo area (area behind the front two seats) can hold 108 cubic feet of water @ 62.4 lbs = 6739lbs.
The Expidition curb weight is 5200 lbs.
So just the cargo area in water weighs 1540lbs more than the entire vehicle. Again, this doesnt include the cubic feet of the remander of the vehicle that I mentioned earlier.
Also the weight of the water I gave earlier is for clear water. Silt and sand increase the weight of each cubic foot of area.
In addition, this over weight vehicle is still subject to gravity which keeps what ever is in contact with the sandy/silt river bottom (tires, undercarriage, roof; what ever is on bottom) drags/plows through the silt/sand.
So a submerged 5K lb Ford Expidition can tax a 50,000 lb winch. It wasnt uncommon for me to have to shovel out silt once the vehicle was recovered just to stay with in the weight class of my rig. A lot of the silt issue has to do with access to the interior and how long the vehicle stays on the bottom until recovered.
