changing a spruce timber mast to aluminum

Hi i`m trying to find information to upgrade a 39ft from water line Spruce timber construction mast, I would like to change it to aluminum but have no idea how much it would cost but I know it would be worth it.
I need your experience.

You'll need to re-rig the boat to do it but I don't see it being that hard to do. It would of course change the wiring up the mast and some of the issues with the main sail. Not sure about where you are or the details of that you hope to do. If you understand the idea of pulling the mast the rest is not that hard. I have not priced a new mast and boom lately though. Some rough dimensions would be in order as well as more specifics on the boat.

I'm sure we could connect you up with someone local to yourself. We have members darn near every place worth being.

Time to think and make notes...

I would suggest having a careful think about what you want. Your question is really like asking "How long is a piece of string?".

Suggestions:-
1) Find the Ixx and Iyy dimensions for your proposed mast. Most mast "makers" will be able to work these out for you. Make a note as every time you talk to someone they will want to know these numbers. Basically they indicate how stiff the mast is to be.
2) Do a sketch of what you want. On your sketch show :-
i) Where each piece of fixed rigging attaches to the mast.
ii) What running rigging is needed
iii) All key dimensions. Ask the mast makers what they need.
iv) All parts that are to attach to the mast. Include steaming, masthead and spreader lights, together with any VHF aerials, SSB aerials etc. Don't forget the hardware that takes the wire from these inside the boat. If you have special requirements for spinnaker/whisker poles or sail track make a note. Jiffy reefing would also be marked.
v) How the boom is to be arranged. This includes any jiffy reefing and bolt rope/sail track and where and how the mainsheet is attached.
Try to get your sketch into digital form (JPEG?) so you can email it to mastmakers/riggers/sailmakers etc.
3) When discussing this with the mast makers ask if they can do the installation/rigging. If they can't then you will need a local rigger.
4) This is a good time to decide if you want a sail bag or roller reefing. Discussion with a sailmaker may be indicated.

Paul, It was built in Germany and sailed to Qld Australia it was built in 91 and a very stable catamaran she has been sitting for a year,
No one whats her with Spruce timber mast and now there are a lot of other problem coming in to the equation due to no maintance so im trying to work out costs to see the value to put in an offer.
