Rule auto bilge pumps have been reliable in my experience. Mine are on 24/7 for 6 months of the year, but needed replacement after three years (kept on a mooring).

If its sat in a harbour then is it the end of the world if it fills up? - The whole point of ribbs is that they can survive swampings and that kind of thing. As long as your battery and electrics are above the "max fill line" (the batt tray is positioned like that on mine) would a manual pump not work just as well? - When you get to the boat - switch it on!

Failing that a small solar panel might help keep the batt charged if you go for an automatic pump?

I have remote oil tanks.. and if the boat fills up with water, than the sometimes they let a little in... I will have two auto bilges fitted this year, one on each battery! And then have a third battery incase they get flat

I have no experience of those Attwood Sahara pumps but they certainly look good. Low current draw too. The manufacturer must have faith in them as they have a 3 year warranty.

What about this?

http://www.jrsupplies.com/bilge-pump-details.html

It is a bilge pump that uses wave motion to do the pumping - useless in a calm marina but would work very well for boats on mooring etc!!!

Or just buy a proper fitting boat cover

However 9D280 makes a good point. Assuming it's rain water causing the problem it might be worth leaving the elephants trunk down for a few hours, let the sea water in and see were it settles. If this level is acceptable then any futher rain water isn't going to make any difference as it just runs out. Where as if the trunk is up then the rainwater will build up and up.

It'll settle at exactly the same level as the seawater the boat is floating in!
