40' DeFever Formosa 40


CELESTE ARC is a Well-appointed, well maintained 40' Formosa Defever motor yacht.  It features low time twin 120HP Perkins diesels. The current owner reports that the engines have been inspected, well maintained and are in excellent condition with no leaks or issues. The hull has been  regularly maintained with new antifouling paint in 2019. This is a solid yacht that should easily appraise at or above the asking price. The boat is ready to cruise the bay, delta and beyond.

CELESTE ARC is berthed in a covered slip in the San Raphael area and the slip is available for transfer to new owner with a possible live aboard option. 

CELESTE ARC is a classic Defever 40 Tri-Cabin Trawler built by Formosa Tai Pai.  The design offers a semi-displacement hull with deep forefoot, flat after sections and a long full keel, giving it excellent handling characteristics in most sea conditions.  The full keel protects her twin shafts from damage.  She has a transom stern, raked bow, raised trunk cabin with midships sun bridge and fly bridge.
