So I have a ~1.5yr old JP widebody that I bought new.

Has been a great board, lots of family and friend use.

I always look after it, don't bash it around.

2nd last time I used it, carrying it back to car the nose is heavy, ie the carry handle feels like it's not on the balance point anymore.

Left it for a month or so, then last time I used it, thought, no must have been imagining it last time, feels fine. However by the end it definitely felt a lot heavier to lift back to car, but it could just be tiredness.

How do I know if it's taking on water?

If so, will it dry out if left long enough?

And what do do... go over it with a fine tooth comb looking for a crack or ding maybe? If so, how do I know the right time to plug it up?

Any advice/experience helpful.
