S/V Wonder is a Miami, FL based 2008 Lagoon 500 Catamaran For Sale By Owner
This catamaran owner requires financial settlement only. No trades.

S/V Wonder is a 2008 Lagoon 500 catamaran, for sale by owner. She has had only TWO owners and has NEVER been chartered.

Wonder is fully equipped with everything that you could ask for, from two electrical diving compressors to fixed stainless steel lifelines that are also extended higher up for added safety. Duplicate and back-up systems, including Raymarine and Garmin navigation equipment, can be found throughout the vessel, as well as a large inventory of extra parts, filters and equipment.

The transom (sugar scoops) have been extended by 1.07m for more stream line sailing, with pull-down ladders on each side. This also makes it easier to get on and off of the boat, particularly when loading and unload groceries or diving equipment. Everything is meticulously labeled and all manuals are still onboard in labeled binders!

This vessel has barely been used, has been well taken care of and customized for long passages. She is ready for any passage and perfect for liveaboards! Includes Starlink Antenna.
