This is the boat Lava Ocean Tours (www.lavaocean.com or www.seelava.com) uses. It holds 49 people and is the largest of the lava boats being used (most are just fishing boats). The 4 250 hp. moters get you to the lava quickly, allowing more time there. When boarding they let those 65 and older board first and recommend sitting near the back of the boat as the ride is much smoother there. If you enjoy extreme white water rafting and/or roller coasters then go for the front of the boat as you get a more exciting ride there (and a bit more water spray)!
