Bilge pump

05 Mar

I decided to install an electric bilge pump.   Following my typical process, I researched on line what was available.  I found several options for both a manual or electric pumps.   The manual pump was the leading choice for many months, as it makes more sense on a small sail boat.   But… I wanted again to challenge myself with some complexity and also thought if I was busy with the sailing on a day with spray breaking over the bow then an automatic bilge pump might be a good idea too.

    Stan: It is unclear to me how you will charge the bilge pump battery. Does you outboard have a charging circuit?

      My outboard does not have a charge circuit, though some outboards do come with this as an option. My plan is to simply keep a freshly charged battery when I go out. I have an automatic charger circuit that I plug the battery into while stored in the garage. My 12 AH battery should provide enough juice to run the pump continuously for several hours. (1.5 amp motor) Usually a bilge pump is run intermittently for a minute or two, so I would guess I will have no issues with using the pump under normal conditions. If I hole the boat and need to run continuously in an emergency condition I should be able to get home or shore quickly with the motor. I also have full floatation built into the boat along with a bailing bucket, and a radio.

    Stan, This looks like a real boat forming. My Marine Electrician landlord can’t wait for the next boat out of my shop with electrical.

    Thanks for setting the bar high, Stan.

      Hi Clint, I have to laugh at myself sometimes while I am building ‘Alice Gail’. I really am quite the amateur and never know if I am doing things right, wrong, or just different. I guess if it’s your boat you can do what you want. That is why my ‘Alice Gail’ has traditional canvas covering over non traditional plywood decking, and an electric bilge pump rather then a simpler foot or hand operated manual pump. I also added forward seats, removing the original design calling for a cross thwart. And earlier in the build I decided I wanted an solid oak stem with a through bolted eye hook rather then the laminated stem design with a hole bored through. And just to be different, I asked and paid for a redesign of the sail plan so I could dip my mast under a local bridge. I now have a Lug rigged sail plan.

      Thanks P, you have been my strongest supporter, next to Gail, and I appreciate your interest.
