Just bought a new Seadoo 2012 challenger 180 SE. I've been boating for years just never have been the person in control of the towing. I understand the dangers involved. And all me and my family are looking for is slow good fun. So the questions I have are for beginners what size line do I need 50', 60'? What's the best tubes for slower speeds like 15-20mph standard tubes or these flat lay down style. Being a jet boat should I use a shock tube or a flotation device by the stern to help with the line staying above water. And lastly do those tow balls really work the booster ball I think they call it. I'm sure I'll think of some more stuff later on. My boat does have a ski mode to set 6 different ramp speeds and I can manually adjust these speeds so as. Of to take off to hard or go faster than I wanted which is a really nice feature. Any tips are appreciated.
