Well I went out on some big water today with the Chief so I never got to open her up, the swells on the lake were huge, some over 4 foot. Wake board boats half sunk playing rap music, massive 30+ footers on about half a plane with 10 people in them, big passenger boats, para sail boats and even sea planes too. Oh yeah there was a bass tournament there today too. The lake I went on Chelan is 50+ miles long and 1500 feet deep at it's deepest and some places a mile wide. It was nice to see the lake again since I grew up there and it's only an easy 50 mile drive. Don't think I've been back in 25 years so it was like a homecoming for us both. The Chief never even got a drop of water on us, totally dry ride at least until the admiral wanted to go swimming that is.
Top speed, I'm thinking the design of the Chief has some serious wind resistance with the double windshields and the big tall bow. Think it's at a wall for top end around 48 but my cruising speed is perfect, 3200 RPMs at 35 MPH and you can get up and move around the boat too without even a wobble.
I've got a few pics of the lake I will try to get uploaded here in a bit. We got the "that's a nice boat" when launching, retrieving and a Starcraft gawker that wanted to see everything inside and out.
