Lifelong mono owner who always charters cats. There are so few downsides on a charter that compared to all the upsides it is a no-brainer. If you go out for 3 hour day sails, or race, or weekend cruiser w wifey, mono fits the bill but a week long charter w 6 or more quests, the cats are awesome. One downside that can be addressed only with the Lagoon 440/450, and as oft discussed on this forum, I really hate the off center, hard top helm. I dont feel the elements, trimming is un natural and the rest of the crew/friends/family are scattered around the boat out of convo room distance. I feel alone (sympathy please?) whereas on the flybridge, everyone sits w me (till they tire of me) I take the bimini down in most conditions and feel the weather and CAN SEE THE SAIL! Just my 2 cents...
