Broker's Comments

The Sigma 400 is the epitome of a gentleman's cruiser racer. She is fast, being able to beat stripped out racing machines, yet with the comfort associated with cruising vessels. Not many out and out cruisers have en-suite toilet and shower in the owners cabin! This yacht was built for the designers brother and has won more trophies than any other Sigma. Quite simply, she is the best!
