Sorry to hear the bad news. There are other good choices out there in which you don't have to pay 700k for a custom/unique boat. Cigs/Outerlimits/Fountain are all great boats. Skater 36 used you can pick up for around 240k+\- and still get some serious speed, same with Spectre. There are a ton of boats out there in all price ranges and like I said before some custom paint will go along way.
Heck, you can even pick up that 42 Executioner with 496's for 1000 bucks a month with 44K down.
You got choices man! Name your price and we'll find you a boat!
Have a good weekend!
