Repower Projects

"Windstone" is owned by David Sharabani of Santa Maria, California. He's an electrical contractor that is trying to find time to go fishing now that he's got a serious fish machine that can run with the best of them! The vessel has the typical " Seaway" look. A little commercial, but still has those lines that appeal to so many. Don't know if you are aware of the Seaway heritage, but just about all of the "Baywatch" boats, here in So. Cal. were made by them...... Widgeon Repower SHOOTER The 4 Year 40 Knot 31 Foot Bertram Odyssey
