Motorized surfboards (that ride above the water so fast they have to wear helmets)
Floating boat airplanes that glide through the cut while floating
Kayaks
Canoes
Giant yachts
Paddle wheelers
Small yachts
Sailboats (which get to have the Montlake Bridge open up for them)
And college beer boats - where summer sport is for boaters with beer to toss the cans into the water for swimmers on shore to collect.
