You might want to look at Jassman's 37 Active Thunder. A little smaller than your ideal, but to make up for it, it will run 100 mph - pretty good trade-off if you ask me ;)

Just a thought...

The faster you go.........the more maintenance is needed
So, be happy with 85 moh and use a more reliable, low maintenance motor...525 EFI

I'm not sure of the speeds, but the 43 Black Thunder had by far the most head room, 6'10". This is Debbie at the Miami Boat Show. She is 5'7'.

Another shot.

One more. This was an impressive boat.

Here's one. You'd have to take the extra bucks and upgrade the power.

blackhthunders are very nice.

if your interested in cushier accomodations, bigger cabin, more cockpit space a sunseeker mght be the ticket. A superhawk isn't goign to run 90mph but they are still prettry quick.

Wow cuda she looks great even with a shirt on!!!:D:D:D

I have tripp 500s in my 42 Sonic and it goes 74 on a good day. If your looking Sonics go with the 45. The cockpit on the 42 is my only complaint. It's a little small. Other than that it is a very well built boat that rides great. Anyone have any pictures of the Black Thunders head? How much room in there?

The owner of a new 46 Black Thunder at Lake Ozark told me it handles terrible at higher speeds and he can't keep drives on it. Has 575s with XRs. You can PM me if you would like his name & number to contact.
