2021 Celtic 40 “Waxy” — US Tax Paid | Owner’s Version | Fully Off-Grid Capable | Recent haul out, bottom paint/service, wax and Polish !
Meet Waxy, a 2021 Celtic 40 (Admiral) — a solid 40-foot bluewater cruiser that offers exceptional value for a couple or family seeking a safe, efficient, and comfortable liveaboard catamaran. Based on the trusted Admiral 40 molds, the Celtic 40 carries forward a proven legacy of strength, balance, and quality craftsmanship with several owners completing their circumnavigations.
Built by Celtic Yachts, who acquired the Admiral 38/40 molds in 2011, these vessels are renowned for their durability, thoughtful design, and strong sailing performance. Constructed using vacuum-bagged, resin-infused sandwich core, the Celtic 40 is a lightweight yet robust catamaran designed to circumnavigate the globe without compromising comfort or safety.
Waxys systems were designed to allow her owners full off-grid capability and reportedly never needs to go on shore power. Perhaps the most stand out feature is the access to the engines from inside the vessel with a large amount of space to inspect and service the engine safely, easily and in air conditioning which is not common on a 40ft catamaran.

The brokerage team has been amazing. They helped me find the right catamaran for our family of four, with enough space for extended family and friends to stay with us anytime. The broker really helped me narrow down what I needed. I started with a long list and eventually narrowed it down to something that was the right fit and price for me.
I cannot speak too highly of Andrew Hodgdon and his colleagues at the Multihull Company.
The process of selling my boat was very smooth and well managed and with excellent communication – especially important as I was unable to be nearby during the sale process. Andrew’s deep knowledge of the market and my boat was very reassuring. We spoke regularly and he kept me closely advised all the way through to a happy sale. I found him a good guy, very helpful, willing to share and bounce ideas around, and I enjoyed working with him. Highly recommended!
Andrew Hodgdon and The Multihull Company are really professional! I just closed a deal with them, and everything was pretty smooth. Andrew was punctual, showed a lot of expertise, and he was honest about all the problems with the boat. He is also giving me the support I need to run all the projects on this boat. This whole process was much better than I was expecting, and I recommend this team! Thank you, Andrew.
The multihull company, specifically Andrew Hodgson worked with me in the sale of Gods Grace, a 50’ Voyage 500. They made sure that as many people as possible touched it, laid hands on it, ultimately resulting in a offer and sale and was extremely helpful in the prep and sale process as I did not live locally… If you want to make sure that people actually see your vessel, will be honest and truly assist you in the sale, Andrew is the man for the job.
