Y'all need to read my reasons before commenting that SIB's don't need pumps and a hand pump is good enough.
My boat has a very nice Hawker Odyssey PC925 AGM battery. Electrical power is not a problem. It also powers my VHF and more importantly my chartplotter/sounder/GPS for finding dive sites, along with providing electrical start for the engine. Next you are going to tell me I don't need a DSC equipped VHF radio, nor a depth finder
First of all I am mostly worried about beach landing and taking a wave over the stern (Been there, done that). There is no driving around and drinking a beer between scuba dives either.
Ian, if you believe a hand pump is more powerful than a 500 gph pump, I would inform you that you are gravely mistaken. I own a nice stainless steel shafted hand pump and it won't even come close to what the Whale Pump can continually kick out. In that same note my electric pump works completely automatically leaving me and my crew to recover the boat back onto the beach, while you are still pumping with your hand pump, as another wave breaks over the stern. A hand pump when you don't have hands available is daft
No wonder I never want to post up my lame work, as someone is always critical when they either couldn't do the work themselves, or think they have a better way.
