You should be able to make it to Leverick on power cat if the flight will be on time. Who you are chartering with? MarineMax has their base at Scrub right now.
MarineMax has moved their base to Nanny Cay.
I think they use both places: when I was there 2 weeks ago there were 3 MarineMax cats at Scrub going through check out process
I saw a sign for MM at Scrub last week too. There were 3 MM power cats in slips. One was partying down, complete with nekkid women running around and a guy talking loudly on his cell phone while being broken up with by his gf. The dockmaster kept having to tell them to turn down the music. It was a circus. When you go to the Willy T, you expect the Willy T. When you go to a slip on Scrub, you don't expect the Willy T to show up...but it did.
MarineMax MAIN base moved from Scrub to Nanny Cay recently according to my MarineMax contact. We're scheduled for a late June into July trip and were originally going to go out of Scrub. We can still do that, but they would send the boat from Nanny with just a captain to brief and check us out. Our contact felt it would be best to go from Nanny, since if there was a problem with the boat discovered during checkout, their full contingent would be available to make it right.
Since our previous 4 trips thru the Moorings required various amounts of adjustments (dead generator battery, inop windlass), as well as missing small items (towels, sufficient rope, an ice chest), we decided to go out of Nanny to be on the safe side. Maybe MarineMax is more thorough than the Moorings but we don't want to take the chance...
