Boat/trailer weighed, is this correct?

[kaliona]

I took my trailer to a local truck scale. The attendant was nice enough to weigh it for free. I pulled onto the scale so my tow vehicle tires were just off the scales, checked weight. Then I unhooked the trailer so it was completely off the hitch, checked weight. The weights were 2780lbs and 2960 lbs respectively. The difference being 180 lbs which I figure is my tongue weight. Is that correct?

Now I'd like to know what my boat weighs. It's a Vanson trailer, single axle, 96" wide (wheel fender to wheel fender) and approx. 18' long constructed of C-channel. I'm guessing 500 to 600 lbs. I plan on blocking up the boat to work on the trailer and would just like to know how heavy the boat is while I'm jacking it up. BTW, the boat is a 1978 Caravelle bow rider, Mercruiser I/O L6 in case anyone happens to own the same.
Thanks

To get the weight of the boat, off load it, leave it in the water, then take the trailer back to the scale. It's weight, subtracted from the 2960, leaves the weight of the boat. Good luck.

your trailer registration should have the weight listed on it...for the boat you can go to nada..look up your year,make,model..it gives the weight on there!

A weight that is NEVER accurate. It's so made up, it's a joke. The ONLY way to know how much a boat weighs, is to do what kaliona has done so far, and then weigh the trailer separately. There is no other way to accurately know. None.

the parking lot.... (maybe)

If it' a single axle trailer weigh under each tire and then the jack, add up all the weights and you have your trailer weight. I've done this with a bathroom scale and it works OK, not 100% accurate as you are relying on the accuracy of the bathroom scale. If you have 2 bathroom scales you could do a dual axle trailer, scale under each tire on 1 side to get the weight of that side. This wouldn't work if the trailer is really heavy and bottoms out the scale.

Once you have the trailer weight, subtract it from the total weight of the rig as TW said.

I never thought to check the registration. It shows 410 lbs unladen weight. Thanks. Now I have all the numbers I was looking for.
