If it's on a mooring then yes it will fill with water unless you have a cover. The solution is a bilge pump but the battery will run down as has already been said. My battery was flat the other day even though it was a massive 140amp. All the rain we have had does not help.
There are two bungs in Ruby's transom, one for deck water, one for hull water. Launching and retrieving off a trailer for a daytrip is no problem, the water getting into the hull void is not enough to be noticeable during the day and whatever does get in empties out when the bungs are removed on the slip afterwards.
But sometimes during Summer holidays I keep her on a mooring, at a pier or at a pontoon, and in those circumstances I have noticed the hull void is filling with water much more than it used to. But even if the hull filled completely, I reckon the tubes would keep her afloat. So I wasn't thinking of an automatic battery-powered pump, just a manual one to bail her before use, so to speak.
Here's an example of my problem. Yesterday I took her out of Cahirsiveen marina in Kerry, not realising how much hull water was in her, and found I couldn't get her up on the plane with 5 people on board. Worse, because the deck drain was now below sea level and it's not particularly watertight, water started coming in on the deck around our feet and sloshing around making her feel quite unstable. I had bring her back into a slip pronto and haul her out on the trailer to get the water out. Now that I know she's taking water, I just thought that if I had a manual bilge pump I could pump her out before using her.
Which brings me back to the questions I posted at the start of the thread.
