Full description
Step aboard Marian, a unique glass-bottom boat. Enjoy the comfortable and a spacious cruiser that will take you on an exciting journey exploring Kona's fantastic reef.

Your tour begins as you board the vessel at Kailua Pier. Onboard naturalists share their love of the sea as you cruise over the reef. See and learn about the vibrant tropical fish, coral colonies, and other underwater wonders. Have your camera ready as the boat approaches Shipwreck Rock, so named because most ships or boats would stay clear of it.

The Marian was custom-made to glide right over the rock, making for unique photo opportunities. finally, head out to the drop off where you see the bottom plunge to over 100 feet deep. Look for frolicking dolphins, or even whales.

GREAT crew - warm, welcoming and accommodating. Nice activity for "unsure" boaters. Great opportunity to see the reefs without getting wet. The Captain and guide went above and beyond to show dolphins - even so the kids could see them. Good job and Thank you!
