Penb's is a good place. I would be a bit worried about theft at Trellis. You can't leave the boat unattended that long. You will have to pay someone to do weekly checks. Talk to the boat broker or Penn and they can help you. Trust me that it will cost you far more in repairs then the babysitting costs if you neglect the boat. It needs to have the systems exercised, engines and generators run and batteries topped. The boat also needs to be opened up and ventilated.
