No, you have a leak somewhere. Put the boat on a trailer, add jack stands at all four corners, and fill it up like a bathtub. Look for leaks that way.
Don’t forget the jackstands, water weighs a lot and you could snap your trailer in half.

Assuming you’ve no big openings like for cables/pipes - as an alternative to office’s approach - which may confirm a leak but not where - make a fitting that connects a hose tightly to the drain bung hole and pump air in (needs volume/flow rather than high pressure) whilst thoroughly covering everything with soapy water - including the deck-hull join which often will mean soaping up the tubes.
