Operational history
In a review, Katamarans reported, "it's pretty easy to see why the Lagoon 450F and 450S are such hot sellers. They hit the sweet spot for the charter market, and they have managed to appeal to owner-operator cruisers as well. Many disparagingly refer to the Lagoon 450 as a 'condomaran', but you can't knock 'em."In a 2011 Sail Magazine review, Tom Dove wrote, "the wind at Annapolis was disappointing, but the big Lagoon’s performance was not. The boat still tacked reliably and moved gently along on all points of sail in zephyrs that peaked at about 5 knots. This was surprising, considering this is a relatively heavy cruising cat loaded with accessories. We did have the optional square-top mainsail on our boat in lieu of the standard full-batten main. Perhaps that’s worth considering if you sail on chronically wind-deprived waters."
