40' Jeanneau Sun Odyssey 40

Dawn Treader is a 2002 Jeanneau Sun Odyssey 40 for sale in St. Martin. She is truly ready to go, a fact that my husband and I have tested every day for the past year and a half as we have sailed and lived aboard her full time in the Caribbean. She sails great and is reliable to live on at anchor, which is why she makes such a great Caribbean cruiser. With a completely rewired electrical system- including all new wiring in the mast- built to ABYC standards, new solar and 225A alternator, new AB hypalon dinghy and outboard, watermaker, navigational electronics, Starlink, and all new Meralon thru-hulls with fiberglass backing plates, shes ready for full time travel and living off grid.

The 1950w of solar fully covers the starlink, watermaker, charging laptops, all navigational aids, MFD, both fridges and daily kitchen appliance use like blenders and espresso machines. The large battery bank also covers all of the boats operational electrical needs for a week if an extended storm comes through. It truly is 100% off grid and is probably the best example of a self sufficient yacht in the Caribbean.

We are looking to move on to another project, which is why we are putting her up for sale. Listed below are a few of her specs along with the upgrades weve made in the last year of owning her. Send me a message for the full listing and picture album, and the out of water marine survey we had performed in 2025, as I cant post everything here.
