I currently have 2001 X-star with stock ballast but want to add additional ballast next to hard tanks in rear that fill via switches already present. So...what's the easiest/best/cheapest way to do that? I already have skylon fat buddies (~280# each) that I fill by hand with pump over the side of the boat.
Take out hard tanks and just put in big fat sacs?
'y-in' fat sac next to hard tanks?(preferred option)
For those that respond, I'm looking for specifics. I'm handy enough to do the work but not smart enough figure out how to set up hoses/pumps/etc.
