I'm in the process of buying a tender for my 480 DB. She does not have the hydraulic platform. I'm planning on going with the Trillogy system and I'm wondering if anyone could recommend a maximum weight. Is 650lbs too much for the boat to handle ? I could go lighter but the tenders I'm more interested in are weighing in at 600+ lbs. Any of you 480 DB owners have any advise ? it would be much appreciated. Thanks
