I have every intention of installing a Whale Gusher Urchin with removable handle along the centre case when funds permit. In the meantime, good friend Dave very generously donated a small Whale Orca electric bilge pump to Arwen. It is a 12V DC pump with a 1.5 amp draw and pumps 450 gph or 28/lts/min with a 1m head.
Followers of the blog will know that I have avoided installing a large 12v battery system for powering small electronics on Arwen. Still cycling, camping and travelling, I buy equipment that will cross sports. Thus I went for a series of small power banks and a Solar panel system for recharging and powering up my VHF radio and camera battery equipment and gimbals.
So why install a small electric bilge pump?
- to pump out rain
- to pump out the rainwater that leaks through Arwen's tarpaulin and collects against the front thwart bulkhead (the drive is steep sloped).
- to have a movable system which can be put in forward or rear cockpit sections as necessary
- a sealed lead acid Yuasa rechargeable battery 12V 7amp
- a Lock n Seal plastic box
- one 12v on-off switch
- 1 thru-hull fitting - 3/4" internal diametre
- a length of smooth bore, reinforced plastic pipe 3/4" internal diametre - I avoided corrugated pipe as it can reduce discharge rates by up to 30%
- a 2 amp fuse and in-line fuse holder
- the Whale Orca 500 pump
- a piece of 9mm plywood which will be varnished and act as the base for the strainer to be screwed to
- various spade and butt connectors
- several lengths of heat shrink tubing
- a small 12V battery charger
