gidday i took the two youngsters across on the boat 2009 xmas time(peaktime) costing around $1900.00 return.went during the day on the melb-devonport run. you could have waterskied behind the boat.like a millpond. we also booked cabins for both trips $80-90 for the day trip and about $110 for the return trip home at night. the cabins were a great idea because during the day you could wander around let the kids burn off a bit of energy,have a look at the bay,the heads ,then they can retire to the cabins for a serious bit of colouring in. i know i said bass strait was as flat as, but it is quite windy out on the decks, as the boat is travelling along at about 30-35mph. food on board wasnt to bad and well priced and we all had a sleep during the day the return trip at night was even better, park the rig,up to the cabin ,hot shower. down for some tucker back up to the cabin ,for a comfy sleep.a buzzer alarm sounds off in your cabin about 3/4 of a hour before docking,hot showers for all ,get dressed jump in the car and home. cabins are good.from memory i think the car/camper/trailer had to be under 2.5 meters high and under 11.5 meters long. exceed these limits and the price changes accordingly. i made it by a 100mm (patrol and a kk). must see places in tassie would be anywhere on the coast,east coast is fantastic, and anywhere in the middle. the facilitys in the parks in a word. brilliant. free bbq, running water, clean toilets/showers great place. also i did not have to unhook the gas bottles from the camper as they are fixed in place boarding the boat is just a matter of getting there at the agreed time, line up in the que, then drive on when directed, easy peasy cheers Graham
