Matching a deep vee Larson FX 1850 DC O/B 2013 against a modified vee Larson Senza 186 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson Senza 186 2009 could be the deciding factor.
