Lagoon 50 - 2020

Sea IO

Yacht description

Sea IO is pristine Lagoon 50 catamaran. Layout is two queen cabins with ensuite bathrooms and one double cabin. The double cabin shares a bathroom with one of the queen cabins and is only suitable for children or one adult. If you require three queen cabins the crew will relocate from the master cabin for an additional fee of $1500.

The salon will seat up to six guests in comfort for lounging. There is plenty of outdoor space on this yacht – the cockpit offers alfresco dining for up to six guests along with spacious top deck seating and lounge area in front of the helm, plus a forward lower deck lounge area behind the trampolines.

Penny's personal opinion

Why book Sea IO – SPACE – There is more space both above and below decks than you would expect from a 50ft yacht. There will always be a quiet corner or alternatively, good congregating areas.  The crew are lovely, very welcoming and fun. A winning combination!

Onboard experience

Crew profile
Even before Dave and Lillian were married, they traveled internationally together and soon discovered a common love for the water. Owners of several watercraft and boats, they lived on a lake where they honed their water sports skills and loved hosting and entertaining their friends and family. Dave and Lillian always looked the opportunity to unwind from the rat race by planning exciting get-aways either in hot sunny spots of the Caribbean or snow skiing in New Mexico, Colorado and Utah. Come discover and share Dave and Lillian’s love of the Caribbean on their new Lagoon 50 Catamaran

  • I am so thankful for having my family on such a memorable trip of a lifetime… The services, food, productions, and cleanliness was perfection! However you both will remain dear to my heart and mind! I feel like I have made new friends. Can’t wait to see you again! May God love and bless you and your family. With love and wonderful memories.

  • This week was amazing! I will never forget the memories we made this week. We couldn’t have asked for better Captains and Chefs! You made our trip extra special. An extra thank you or all that you did for my babies… time of their life! Til next time…

  • We had a wonderful time! Lillian and Dave Harkness were excellent hosts. Lillian is a fabulous cook and exceeded our expectations at every meal. She carefully took into consideration our preferences and dislikes. Even my youngest, who is sometimes a picky eater, enjoyed her meals and drinks.

    Dave prepared an itinerary that was detailed yet flexible and we were able to hit all of our “must see” locations and activities. They assisted with taxis on land for dinner, shopping and getting to and from the airport. They also were very helpful in arranging our necessary covid testing prior to departure.

    The yacht, the Sea IO, was comfortable, clean, and ran smoothly. It had several open seating areas that accommodated the whole family for meals and games, so it felt spacious. Dave was a competent and experienced captain even in some tight spaces.

    Overall, it was a great experience, and we would definitely consider it again in the future at other locations.

  • Captain Dave! I’m sure you heard from Dad and Daniel, but I just wanted to personally reiterate how grateful I am for this trip. We had a lot of excitement and anticipation for our charter, but once we met you, you blew our expectations out of the water.

    Yes, the beautiful bays and sublime snorkeling were a treat; Lillian’s homemade cooking were over-the-top delicious, your willingness to pass on stories and sailing expertise was unforgettable. But the best part of it all was the late-night laughter and the gradual building of new friendships along the way. You and Lillian truly have a remarkable way of making guests feel welcome and inspired to take on the adventure of sailing the seas and exploring what God’s creation has to offer. I loved learning and testing my own seaworthy skills under your direction, and I left on Sunday feeling almost sad that it went so quick.

    Thank you for the great memories, and know our entire group enjoyed our time with you. We’d love to write a review or offer any feedback that would help you both as you continue to look for charters.

  • The Vilas Family

    What a beautiful trip! So many laughs and memories! We had an unbelievable time! You two are the best!

  • The Wickes

    Thank you for the truly exceptional experience! Our charter greatly exceeded all of our expectations from our accommodations, to our gourmet meals, to our activities in the water and on land. Sea IO Lagoon 50 was very well equipped with all of the toys and luxuries, was very spacious and comfortable in all the living spaces and cabins. Even the dinghy was top notch! Thank you for the vacation of a lifetime!”
