She completed several half-marathons, a full marathon, and several triathlons. As a child, Lillian lived in Mexico City for 14 years where she grew up enjoying the delicious and bold flavors of the country. It is the combination of these flavors, some family recipes, and the fresh ingredients of the Caribbean, that Lillian has incorporated into her menu and drink fare for you to enjoy.

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.

What a wonderful time that we will never forget! Thank you so very much! Till the next time!
Lillian and Dave Harkness were excellent hosts
“ 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. “
Jay Bell - 03/17/21 Charter Feedback
“ 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.”
Wickes Charter Feedback
“Thanks 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!”
