Re: New mast?

Post by Castaway »

As I've mentioned, the PO broke the original aluminium mainmast on Castaway. It wasn't apparently, violent or spectacular: the mast just flopped inside the sail. He said it was due to a strangely cut sail, not any violence such as collision. The UK masts were built by Proctors, and we still have the original mizzen. The inner sleeve, in the lower part, is a very close fit, and also held in by a lot of stainless steel machine screws threaded into the aluminium; there until the corrosion rots the entire mast, I think. They stick well into the interior of the mast, which makes passing wires internally a frustrating source of invective!

The mast is tapered along its length, with no step at the join, and the crane at the top is welded in place. It is the same length as the new main, a CF spar made in the USA by T.P., and imported specially. (He must have had very understanding insurers!) The aluminium mast is nearly twice the weight of the CF one, and smaller in diameter by about 1 inch (2.5cm) at the heel. It is my impression that it is a mite less flexible, too. George, the PO, told me he had once got into a wind acceleration zone in the Canaries, with a staysail set, and the running backstay broke; He said the bend was spectacular, but nothing broke during the minute or two it took to drop the staysail.

I'd love to have a replacement CF spar, but suspect the cost would be at least £10000. An F35 recently sold in the UK for about three times that, with two CF masts! I think there is a firm at Caley Marina in Inverness which makes CF masts, if ever your insurers are looking for a manufacturer. It probably would be as expensive to get a one off tapered aluminium mast made as a CF one.

Look after those spars, but I doubt if you could break one just by sailing with the usual wrap around sails, in any weather.

Let me guess.....'some rather low technology application of force': a sledgehammer?

Gerald, in 1997 I asked Carbospars what a CF mast for an F33/35 catketch would cost. They quoted UKP 4000, if I remember well. This quote was backed by Brian Butler of Ancasta as being a fair quote. Brian was the most Freedom knowledgeable person in the UK at the time.

i need a repair on a f39 mast . The mast seems like it was broken just above the deck where the mainsail is. It was broken by Sea Tow after a storm when she broke loose from her moring in Port Jefferson harbor New York . the sea tow guy attached a line to the mast to right the boat off the beach when he snapped the mast off the boat. well thats the story I was told by the managment at the boatyad . Now I bought the boat and about 6 feet of the bottom of the mast is missing and the step plate to mount it in the bilge wih I have no idea what it looks like I would greatly appreciate a picture of the mounting plate for the masts I think there both missing! I have alot of work ahead of me I know so please help me.

Hello Arthur,
I had my 2 masts replaced on my 39PH after meeting hurricane Jane in 2005.

I measured all dimensions of the broken masts and kept the main parts to draw plans of the replacements

I asked several carbon spar builders for quotes, and Ted Van Dusen http://www.vandusenracingboats.com/spars.html had the best product and price (17.000$ for the main and 12.000$ for the forward mast). The new masts are significantly lighter than the original ones.
The new masts have a Tides Marine track installed

The construction technique is quite sophisticated when compared with the original mast: the new masts are "woven" in one piece, put in an autoclave for a while, etc. No circular cracking as on the original masts (I previously owned a F33 wich masts had circular cracks all the way up; this was strictly cosmetic... Same with the original 39PH masts)
I have more details (VISIO CAD files) if you want to join to your quote requests. if you are interested, let me know. Good luck!

yes I have decided to repair my CF mast with aluminun . I found a flag pole manufacturer right next door to my town in Port Jefferson New York that can and has done it before the only dimension I need is the mast lenght for a 39Ph catch schooner made in 1982 ! If any one can relay that infomation to me I would be greatly appreciative to them .
I still have to figure out a design for the mounting steps to secure the bottom of the mast in the bilge. I also have to make up a design to hold the for mast in pace up in the bow as someone has stolen both peices .

Hi Arthur,
Here are the plans I submitted to have new masts made for my 1983 PH39.

In addition, you will find the "keelsteps" drawings for both masts.

These steps are bolted on the bottom and the masts simply slide on it. A single bolt on each mast keep it from lift off the steps when sails are down.
Hope this will help
