Do I need bilge pump/pumps???
 
It seems like every day now I have another inexperienced question to ask you guys!! So far you lot have came through and I've all problems sorted to date😀
I've only a few more things to tackle over the winter, filling a few chips in the gel coat, seating and then paint/gel coat everything! Any tips and advice would be greatly appreciated!

My next question is, do I need 1 or 2 bilge pumps? One for sump area and one for hull? Would you recommend solar charger for the battery if left moored?

I suppose it all depends if the boat is built with self drains and if they work well. In theory all hull compartments should drain aft But mine don't so where they don't I have a bilge pump

I had a boat flood on land cause the battery went flat, so a half decent solar charger is essential in my mind

It has self drain trunks and a bung between the hull and deck sump. So far I always leave the hull bung in and just open it after I've drained the small sump area. There's never any water in the hull but wasn't sure if I should leave the hull bung out and use an auto bilge pump to aid draining the deck/sump

If its's designed with a BILGE WELL,I'd have a bilge pump fitted for sure:thumbs: I don't like water sloshing about on deck..an auto is fav for me,turn on and forget,comes in handy when the weather is rough/bad!...and on a mooring when it's monsooning,especially over night.

The trunks are only really for a Stuffing or Swamp when you need to dump water fast...I only bother to deploy them if it's really Knarley...as precaution.

Bilge well:facepalm:
New pump it is then! Any recommendations? Do I leave the bung in place between hull and bilge well as I have been or open?
Cheers guys!

If you have the set up I think you have..definitely keep it closed.You'll fit bilge pipe to pump the water out through the Transum.
I may have some bilge pipe and switch/fittings...pm me and I'll have a look.
Pumps?...Whale and Rule have both worked ok for me.

Are you going to keep it afloat for long periods or just "overnight"?

Nordburg2001 16 October 2016 17:32

At present it will be afloat 1 or 2 nights at most but next year it may be moored over Easter and all summer

Its really surprising how much water a RIB can collect without an Auto Bilge pump overnight in a Bad downpour!:eek:..every drop flows towards the back end (as its meant too) and can soon get half way up the Transum where a lot of the weight is already!....as the Boat dips in the water it exasperates the effect....small Boats suffer worst..how often Have you seen Tenders sunk in Marina's?
I was Towing for a trip to the Scillies a couple years ago and Hit Torrential/Blinding rain on the M5 which was leaving standing water on the Motorway and slowed us to a crawl.
In only 20 minutes I had half a deck of water!....and had to switch on the Bilge Pumps while we continued down the Road to Rock!:D
If the weather looks Bad for extended mooring periods I'd use a cover.

A well designed rib shouldn't sink even if filled to the top of the transom with water. But it would certainly be exasperating if it did ;-)

do you not tow with the trunks down/bung out?

agreed - it also helps keep the birds and sun off etc.

If you are going to keep it afloat all summer then even with a cover I think most people ship some water, and life bilge pump. A solar paner will help stop the battery being completely drained, but you might want to consider a second battery and or some remote monitoring of voltage so you don't get nasty surprises? Will depend how often its gets used.
