Replacement Mast Questions

Hi All,

This is my first post so please go easy on me :D 
I am fortunate enought to have just become an owner of a Catalina 36 MK2 which is a dream come true.
Unfortunately at one point in its life it has had an incident which resulted in the mast being removed and unrecoverable.
I have found another mast which i am told will fit and the previouse owner of the boat has measured however i would just like to see if anyone on here is able to confirm or knows of any reason i should not go with this particular mast.

The details of the new (second hand) mast are below:

This mast has just been removed from a Swan 36. 
Keel stepped double spreader rig.
Selden mast section E177
177mm x 124mm cross section.
0-deck  2.15m
0-vang attachment point 2.35m
0- gooseneck 2.95m
0-1st spreader 6.22m
0-2nd spreader 10.41m
0-top of the mast 14.60m
   
  
  I  13.07 m  
 J  4.17 m  
 P  11.6 m  
 E   3.99 m

i am completely new to this so please let me know if you need any more info.
Many thanks

   I don't have an answer for you at the moment -- not close to the boat at present, otherwise I'd take some measurements for you.   But at the risk of being seen as an imperial measure chauvenist, however, I'd offer the suggestion that you might want to consider editing your post to also include the measurements in feet and inches.  
   I sat this only because my sense is that the great majority of users on this site reside in one of the three remaining nations that (for some inane reason) have yet to adopt the metric system (Myanmar and Liberia being two of them).  So they don't "think" metric, probably don't have metric tape measures on their boats, and may be less likely to get out their calculaters and do the conversions to imperial measure in order to help you out.   
   (And yes, perhaps those of us in imperial measurement folks could return the courtesy and post in metric as well!)
   Regards -- and welcome to the C36IA!

You rig would be a bit short. Here is the measurements from sailboatdata.com I also believe that the 36 was a single spreader rig suggesting that your mast section may be more bendy than the stick Catalina provided.

Hi,
thanks for your replies,
it looks like i will keep on looking for a replacement mast. I would like it as original as possible so this one will not work out.

thanks

Russ,

I think in this case you are making the correct conclusion, that this mast is not the right choice.  But you need to consider other aspects of the mast other than dimensions.  First :  The mast section must fit the " shoe " ( What the base of the mast sets in ).  Second :  You need to consider the shrouds, their number and their length.  The Catalina 36 has a single spreader with One (1) upper shroud, and Two (2) lower shrouds, forward and aft [ Connecting to Three (3) chainplates ].  The double spreader mast would have One (1) lower, One (1) intermediate, and One (1) upper, all connecting to a single point ( chainplate ).  I don't think that would work well on a Catalina 36.  It would require fabricating a bracket to attech all three (3) shrouds to a single hole chainplate.  Not sure I would be happy with all that load going to a single chainplate. The length of these shrouds could be an entirely different problem

Russ have you tried consulting with a RELIABLE rigger?   You might give that a shot.

Hi Bill, Thanks and yes just spoken with a rigger regarding the consensus is the same so will look into getting one made.

Thanks anyway
