2007 Lund 1800 Explorer SS The big Lund 1800 Explorer SS has plenty of room and comfort for everyone. The wider beam and IPS hull create a more stable boat that is also faster and smoother running, which makes everybody's day more enjoyable. There's also plenty of Lund fishability, starting with Lund's ProTrak and SporTrak gunwales. And for a final touch, add the trusted power of a Mercury outboard.
