TOT, I just placed an order yesterday for a L450 via Simpson Marine
here in S'pore and asked this very question. The answer was that Lagoon
hasn't any significant planned changes for the boat in 2014. I was also informed that they are quite secretive about releasing upgrade info. I would still pose this question to your agent/broker however.
They are however testing flexible solar panels
fitted above the rear deck
roofing as Lagoon are seeing a nr of clients not taking their standard design and doing their own thing.
