The Rave's draft is about 6" with the foils retracted. There is a "half-latch" position that has about a 2' draft and the fully extended position is a little shy of 6'. The foils have to be to be fully extended for flight.
Beaching the Rave is like any other beach multihull. Without leaving your seat you can retract the foils on the amas up to half latch and head toward the beach. As you approach retract the amas foils fully and leave the rudder at half latch. Then, you can hop out into 2' of water or simply fully retract the rudder and come up onto the beach.
Alternatively, because the boat will sit up at half or full latch you can hop out of the boat, pull it up into shallow water and then extend the foils down to half latch. That supports the hulls above water in it's "drydock" position.
Recovery onto the trailer is simple from a beach launch. I pull the boat up onto the beach a bit and then raise the boat up onto fully extended foils. Then, I back my trailer underneath the "suspended" boat, get out of the car and let the boat down on the trailer and drive onto the hard to disassemble. You can do the same at a launch but the bottom can be slippery sometimes. The hardest part of recovery happens when you are at a beach where you cannot get the trailer backed fully under the boat. Then, you may have to lift the bows up onto the trailer. It's 400 lbs and sometimes needs an extra hand simply because the boat is 17' wide and a bit unwieldy when shoving from just one spot on the boat.
I regularly hit at least 25+ (mph) and very often 30+ when there's a breeze. One has to have an airhorn to alert the jetski's when you want to pass them.
