Bagatell Conversion Update January 12, 2001

One begins to really appreciate the scope of this project when looking at all that has been accomplished and just how fine a boat this is turning into.  Despite winter acting like winter for a change, substantial progress  continues.  Externally, the heavy railing on...

Bagatell Conversion Update December 14, 2000

Cold weather has been making painting slower to accomplish, but every break in the weather sees more of the finish coats being applied.  Much of the work has shifted to the interior of the vessel where many of the systems are being tied in and completed.  Most if not...

Bagatell Conversion Update November 21,2000

Progress continues on all fronts.  The entire topside has been sandblasted, and given 3 coats of primer.  The wheelhouse and mast have received the white topcoat to allow installation of doors and windows for closure against the elements.  In the meantime, the 30kW...

Bagatell Conversion Update October 30, 2000

Bagatell Conversion Update July 30, 2000
