Terry,
I have a Maristar 210VRS and have e-mails from a number of WW folks that also have Maristars. Here is what I was told…
Start with a full sack 550-600 on either side of the engine. And a locker sack (350) pushed all the way to the front. You can get a bit more than 350 in the ski locker but will have to custom order a sack that is long enough to run the whole length of the ski locker. See
http://www.letsgoride.com/ a lot of good feedback on their stuff.
You can run a 550 on the floor in the walk through or give up storage and run sacks under the seats. You can fit almost 500 of water weight under the bow seats but it is more of a hassle to fuss with filling 3 separate bags than it is to fill one sack on the floor.
Use the hassle factor and ‘play-pen’ style bow argument if you get grief from the boss about having bags on the floor.
You may not need to fill the rear bags all the way full. Depending on how many people you have in the boat.
Last year I ran 350’s on either side of the engine. 350 in the locker. 550 in the walk through.
This year I am running 550’s on either side of the engine. 350 in the locker. 400+ of lead under the bow seats. Nothing on the floor. More weight in the back makes for a steeper wake.
Good luck. Shoot me an e-mail if you have any questions.
