Advertisement Posted June 11, 2010 Posted June 11, 2010 Hi Sailronin, Take a look here Mast removal on 165 foot sailboat. I'm sure you'll find what you were looking for!
Sailronin Posted June 11, 2010 Author Share #2 Posted June 11, 2010 (edited) [ATTACH]206836[/ATTACH] Two cranes needed to do the lift. Notice the size of the people around the mast. This mast weighed about 12.5 tons and was 178 feet long, the mizzen (smaller mast) weighed 8 tons Work done at the Composite Works shipyard in La Ciotat, France Edited June 11, 2010 by Sailronin Quote Link to post Share on other sites More sharing options...
likalar Posted June 11, 2010 Share #3 Posted June 11, 2010 Fascinating series, and nice captions. Quite an engineering feat. Is the mast being modified, readied for transport or ??? Larry Quote Link to post Share on other sites More sharing options...
stuny Posted June 11, 2010 Share #4 Posted June 11, 2010 Dave - A very interesting set, well documented. Quote Link to post Share on other sites More sharing options...
Sailronin Posted June 11, 2010 Author Share #5 Posted June 11, 2010 Hi Larry and Stuart, The masts are just down for routine maintenance. Every four to five years the rig must be pulled and the solid rod rigging (stainless steel about 1.5 inches in diameter at largest) must be inspected and replaced. Not a trivial matter in time or expense. Thanks for looking Dave Quote Link to post Share on other sites More sharing options...
pauledell Posted June 12, 2010 Share #6 Posted June 12, 2010 Dave, A great series that should appear in a boating magazine as part of an article. Nice reportage. Paul Quote Link to post Share on other sites More sharing options...
daveleo Posted June 14, 2010 Share #7 Posted June 14, 2010 Advertisement (gone after registration) very nice series . . . i was confused about the mast not flipping until the second set of pictures showing the other lifting point (and crane). i am stunned about the weight ! i assume it's steel? hollow? . . . .do you know? in the olden days (pre-retirement) I witness some turbine lifts (200,000 # + ) . . . no mistakes allowed . . . as i am sure is true here as well.

Sailronin Posted June 15, 2010 Author Share #8 Posted June 15, 2010 HI Dave, The mast is Aluminum, the standing rigging is stainless steel. On the higher tech boats the masts are now carbon fiber and would be about half this weight. Thanks for looking, Dave Quote Link to post Share on other sites More sharing options...
