Depends which weight of a boat trailer you mean. It also depends on the length of the boat trailer. For example: A relatively small (6.40x2.09 m) Respo double-axle boat trailer weighs roughly 400 kg (880lbs). The bigger ones (more than 8 meters in length) can weigh around 900 kg (2000 lbs).
The boat, yes - the trailer, no. Rest assured, they've dealt with this situation before, and are adequately equipped to deal with repossessing your boat while still leaving you the trailer.
24 continental boat trailer that is designed for 24 feet will typically be rated anywhere from 3500 to 7000 lbs depending on axle axle configuration. Trailer Depot of Miami 305-224-3564
900 pounds
An 18' Aluminum Single Axle Trailer is 575 lb.Bruce at All American Trailers
could be anywhere from 2450 to 2900 lbs, I have a 22 foot Crest pontoon and it weighs 2840........you can take it to the truck stop weigh the boat and trailer, then drop the boat in the water and go back and weigh the trailer and subtract the trailer weight from the total weight
500-600lbs
Semi-trailers come in different sizes and not all are made with the same materials and components or extra features. A 53-foot empty semi-trailer can weigh anywhere from 10,000 to 25,000 pounds.
A tilt trailer is the best type of trailer to have I think, since you don't need a boat ramp to launch your boat. I have a tilt trailer. First, make sure your boat and trailer are balanced properly. The boat weight should be forward of the axle slightly, so that the trailer does not tilt when the bow of the boat is touching the bow stop. Balance the trailer and boat by adjusting the axle and bow stop positions on the frame. (The tongue weight also has to be right, of course.) Also, if your trailer has bunks, the majority of the boat's weight should be on the keel rollers and not the bunks. Finally, all the tilt trailers that I have seen have a safety chain wrapped underneath the trailer tongue to keep the trailer from tilting too much. I think that's a good feature to have. When launching, back up to the water (on the beach or boat ramp) until the water is deep enough. This depends on your boat and prop length. For my boat, I back up until the water level is just below the wheel bearings or axle. Pull the tilt pin. Also, some tilt trailers have a lever that lowers the bunks to reduce friction. Start to slide the boat backwards, holding onto a bow line. If your boat is heavy, you may want to use the winch to control the speed, as the boat can accelerate as the trailer tilts. As the boat moves backwards, the trailer automatically tilts back. The boat just rolls along the keel rollers into the water. When retrieving your boat, the process is just reverse. As you winch the boat up on the aft keel roller, the trailer automatically tilts back. As the bow reaches the bow stop, the trailer frame levels out again. Before you drive off, remember to replace the tilt pin! A tilt trailer is pretty easy to use and you usually don't have to submerge your wheel bearings in the water!
Very hard to answer because it varies depending on the weight of the boat and trailer. The best way to determine this is look up the boat model or ask the dealer who sells it how much it weighs. DO the same for the trailer. But the most accurate way is to tow the boat and trailer to a truck scale and weigh them.
"50 pounds"?? Maybe he's referring to the Approx. weight at/On the hitch? But trailers certainly weigh more than 50#'s! More detail would have helped/ I just had a trailer Deliver, that requires assembly, and the weight is 126 Lbs. with 8" wheels. This is for a 12' to 14 foot Boat Trailer Alone. 12" wheels would be heavier with the Larger axle and bigger tires. I'd add (guess) 100 lbs.? for that situation I think this better answers your question of the "weight of the trailer"
The hull is approx 2500 lbs dry, no motor , gas, or rigging. This is listed on the Mako website under years 1968 - 2007. Mine has a 225 hp merc (500 lbs), double axle trailer (1000 lbs), and fuel - 121 gal another (1000 lbs) - total weight with fuel, motor and trailer - approx 5,000 lbs.
