Uh huh...watch the wire passthrough...
I had the same issue - and also planned on pulling out the tub and rebedding it - but I ended up running a bead of (oh no...) silicone around the inside of it.
I ran it around the edge of the locker - and around the base of the port/back pulpit base where the wires go in (the wire hole and around the base itself, so the water does not go down in there) and it stopped (so the project has been pushed back).
This is an area many people miss
and Ericson's stanchion bases were/are horrible (without drain holes on all of them so the water just sits - and the one in question - it just runs down the pass through - making a perfect leak).
As an aside - try sticking your head into your forepeak (lay on your side), and look to the high left - check your wiring bundle is out in front of the woodwork, etc - so any water coming in on it drips down the drain - not onto the wood, and into your veeberth.
Try that for now to hold it off until the dry season - then rip it out and rebed it.
Goodluck -
