How slow and/or pokey are the Lagoon 39 and Leopard 40?

[tripletrouble]

Here is my situation: I for some reason like the looks of the Lagoon 39 and Leopard 40 but from comments elsewhere as well as perusal of the Multihull Dynamics data, they come off as extremely low performance.

Thing is, I want a 40ish footer for use on the lower Chesapeake with occasional forays as far a Annapolis to the north and possibly the NC and Delmarva coastal waters. Most of the time however it will serve as a weekend/holiday getaway in lieu of a shore based vacation home. Both would fill that requirement but having sailed small multi's and high performance mono's I don't want to be embarrassed by being "smoked" by similar sized mono's.

Opinions, please?
