The short answer, no.
Did you need the muscle to lift it at the tongue, in which case the boat is not set on the trailer properly, may have to move the front upright with the winch backwards, or move the axle forward.
If the muscle was needed to roll the trailer, then there is probably a problem in the bearings. How long was it sitting? You could try pumping grease into them but I wouldn't tow it without pulling the wheels/bearings off and inspecting.
Hope this helps.
