Very nice Arima! I had a Sea Chaser for about 10 years and really loved it.
I agree with the Arima website - lots of friendly and knowledgable people on there.
One suggestion I would make would be to add Smart-Tabs. I got a lot of differing opinions on the Arima site, some said Smart Tabs, other said they were a waste and to go with electric or hydraulic tabs.
However, for me, the Smart Tabs were the best thing I ever did on the boat. Much less expensive and no maintenance, and they made a huge difference in my ability to jump up on plane faster and to plane at lower speeds.
Some rocket launchers and a nice radar on that hard top would also be pretty sweet!
