I'm upgrading the ballast bags and pumps on my 2007 Supra 22SSV:
3 - New Pumps.
2 - 750#s in the back.
Leaving the Center with the Gravity III Sac that came with the boat.

I have the walk through bow with the front seats. Looking for options and opinions for the front ballast:

Option 1– Should I buy the bow-sac for under the front seats?
About 650# full weight – probably fills 400-500#
Plumbed to the Center Locker Bag
Sits out of the way – does not take up any room.
More expensive - $269 for the bag plus some plumbing parts

Option 2 – Use one of the replaced rear-sacs from back to sit in front of the locker/between the seats
About 4000# full weight
Need an add’l pump – over the side of the boat
Takes up room between the seats.
Less expensive – New pump + so some plumbing parts

Option 3 - Other?

What works best on your boat?
