The reason it's not leaking when your in it is because you have increased the pressure on the hull and the aluminum cross members thereby sealing it better. When it's just sitting, there is no inward pressure on the hull and water is getting in around a couple loose rivets as the hull expands and contracts with heat. Aluminum has a LOT of thermal movement.
For a temporary and quick fix, seal over the rivets with a high quality silicone from the outside. You don't need much. For a permanent repair, replace the loose rivets.
Good Luck!
P.S., if your boat is not aluminum disregard everything above!

thank you for the idea, it is aluminum and it is a welded hull, but there are some rivets I holding the bracing for the floor (floor supports are aluminum and built with the boat) I don't believe seeing any below the waterline except the stern, think I will pull it and do it,
any others?
