The Ed Robinson Fleet

Your safety is our number one priority. We ensure that we use the best boats for your safety at sea.

Sea Spirit has been in operation since July of 1999.  Designing a boat as an improved sister ship to our original boat, Seadiver II, wasn’t easy, but we think that once you’ve dived from her, you will agree that she is as diver friendly as any boat made.  Two big improvements are the camera tray and camera rinse bucket. The dive ladders are also improved to accommodate fins on the bottom steps.  She also incorporates the side dive door system and all of the features that have worked so well on Seadiver II.  There’s more, but you will have to experience her first hand to really understand what makes this boat so special.  And, in August 2014, we just had two brand new engines installed, so Sea Spirit is ready to go for several more years!

  • Dimensions: 32′ X 10′
  • Planing hull for faster speed and less travel time to the dive site
  • Coast Guard Certified: 16 (4 crew and 12 passengers)
  • Forecastle: enclosed head (toilet) and dry storage
  • Camera/storage table above tank racks
  • Large covered area for sun protection
  • 50 gal fresh water rinse and hose down
  • Camera fresh water rinse tub
  • Ample seating w/gear storage under each bench
  • Center tank racks incorporating fin & mask storage
  • Side dive doors for easy water entry
  • Large stern dive platform
  • 2 stern fishbone ladders (bottom rungs have side access for divers wearing fins)
  • 1 side fishbone ladder (we’ve found this the safest position to climb on board while anchored in rough water)

The builder of Sea Spirit is William E. Munson Co., the same Bill Munson that built our first boat Seadiver II.

Aloha! I want to thank the captain and crew of the Sea Spirit for a fantastic experience diving at Molokini at Crater. This was the first dive I've taken without my own buddy in tow, so I was hoping to find at least one friendly diver on the boat. Instead I found 3 crew that instantly felt like friends and a small group of fun loving divers who all stayed together safely as a group, guided by Ricardo who pointed out all the interesting creatures below, from sea turtle to octopus. It was like a dream and I can't wait to return to Maui for more diving. Mahalo!!

We dove with 3 different outfits in Maui. All were very good, but yours was the best. The Adventure-X trip on Wednesdays was perfect. We dive a lot at home and prefer being around advanced divers. Ed's crew handles dives perfectly: no rushing, maximum bottom time, safety. The backside of Molokini was amazing. Also, splitting the 2nd tank into two short dives was very considerate. Other operations would have burned the entire tank at one location. We'll be back!


This is my third trip to Maui and diving with Ed Robinson's diving Adventures and I LOVE IT. I probably did anywhere between 50 and 60 dives with ERDA, Molokini back and forth and along the East Coast of Maui knowing all the cool reefs, wrecks and 'secret' spots. Not only I always enjoy the 'hang loose' characters of the dive masters and boat crew, no it's like meeting friends and almost family. Been 'lured' to other dive ops around Maui but keep bouncing back to ERDA. As an enthusiastic diver, photographer and videographer it's a great pleasure to go back to the SEA DIVER and SEA SPIRIT every week. There is no better Maui diving than with Ed and his excellent crew. Mahalo and Mele Kalikimaka.
