SFG Yacht Design Reveal F16; F18 Console Yachts If you are in to console-style yachts then what SFG yacht Design recently released will pique your interest. The F16 and F18 designs are the latest from this Italian design house. As you can deduce, the design comes in two size lengths and variations. The F16 is a 16-meter as the name suggests and is powered by outboard engines while the F18 is 18-meter and run by inboards. Other than that, the two boats are pretty similar.
