Water if forward bilge after rain

[lenoah]

We have a 2004 Tiara 3200 Open.  After heavy rain the forward bilge has quite a bit of water.  Due to the V of the hull at that point, the bilge pump leaves several gallons unpumped.  I'm talking about the forward bilge -- below the companionway steps.  Engine room and aft bilge stay relatively dry.

Anyone else with this issue and an idea where the water is coming in?  I taped off the chain locker hatch before the last rain and still got water in the bilge.  No signs of leakage anywhere in the interior.

Thanks in advance for any clues.
