The Salvage of Shields #231

Shields #231 sank in 60 feet of water in 1999 by swamping in an Easterly.

She was floated again on October 2, 2002 by fleet members H.L. DeVore
and Bill Gerety

with significant assistance from Lada Sinek, Howie McMichael and Bo
Bohmert of Bohmert Marine.

#231 is due to be refitted and rechristened "Mermaid" and will be
rejoining Fleet #1.

I was particularly interested in the Corrosion picture.
Stainless and aluminum (aluminum loses) but it took 3 years underwater -
in salt.
