Swinging mooring - bailing out

I have just moved my 4.5m rib onto a swinging mooring in April. Currently I am having to bail out 20cm of water each time I go out ! I am reluctant to fit an automatic bailer because I am concerned the battery will work overtime and go flat. I know we have had excessive rain this month

I have found a Drainman wind/wash auto bilge pump - but this seems to be designed for fix mooring boats. The obvious choice of a cover doesn't seem practical because of fixing points on the rib/wind. I leave the transom bung in when moored.

- Any advice on limiting the amount of bailing welcome !

Something like this solar powered thing Solar Bilge Pump by SeaJoule, perhaps?

I suppose it depends how big your battery is, but I've left my boat on its mooring for months at a time and never had a problem with the bilge pump running the battery flat. You may be worrying unnecessarily.

I keep my boat on a swing mooring on the west of Scotland granted I have two 120 ah's on a reg but only one to the pump. This is backed up with a solar panel. Only in exceptional circumstances and over a period of 4 weeks really bad weather have I ever had problems with flat battery.
Hope this helps.

Thanks guys. I think you have put my mind at rest and I should try an automatic pump to the bailer - I like the idea of Solar back up if I need it.

What about using a wave powered bilge pump like this one? : Mailspeed Marine Drainman Wave Operated Bilge Pump, Bilge, Saltwater & Shower Pumps | Mailspeed Marine
I've not used one personally but it looks like it might help minimise your battery usage.

I tried one years ago you need quite a big raise and fall which you don't achieve in a rib

How about using an overall cover?

Unless v sheltered, a cover is a nightmare to put on in winds when in a dinghy. Also v expensive when they come off and tear.

Re your battery, just make sure you give your bilge pump a good clean once in a while. Most likely issue will be when the float mechanism gets dirty/old and sticks on! We've only had this twice in about 12 yrs though. Worth mentioning.

Yes, I think trying to get an effective cover will be too much phaffing about in a tender out on the water. The bilge pump will go in this weekend.

Thanks for the advice.
