Typhoon Daysailer Mast Stepping

[mashenden]

... I saw two TY's sailing on the Piankatank yesterday...
Roger

Wow - that is impressive!! There were 70 mph gusts not too far west of us. I am envious (and apparently getting soft)

[trapper]

Matt, I have a call into my friend. I think he used a fence post from Lowes and either an electrical conduit or a metal water pipe also from Lowes. One fit inside the other.
He will let me know details
Here is a post from Ensign Class forum:

Gin Pole

Joel, I know exactly what you mean about trying to find an old suitable mast. I have been looking for a few weeks now. Thanks for the info. Mike... Michael Holt

Two 10-foot sections of 2" aluminum conduit threaded together also work well. Mike Scott ________________________________ From: Michael Holt... Michael Scott

Thank you!!! Apparently the link has changed, but that was enough info to figure it out.

To those interested, here is the link showing the Gin pole in use. http://www.sailsaratoga.org/content.asp ... e_id=67958

There is plenty of detail to get the point on how to do this on a CD Ty Model K. I have not found measurements yet, but it stands to reason that the Gin pole has to be about 4' longer than the distance from the cuddy top to the spreaders.

Any idea on what type of Gin is required? And can one substitute Rum?

[mashenden]

I wonder if using 2.5" PVC pipe and some additional mid-stays would do the trick? Cheap and readily available at any hardware store. I think I will give that a try when my time comes (think Spring, but probably Summer).

Once upon a time I considered myself an "expert" on Gins - with a lot of practical "real world" experience under my palate. If you truly care about your Cape Dory sailboat I would recommend Bombay Sapphire Gin. Possibly a few more "boat units" but worth it. I would not recommend substituting Rum - you will not be happy.

I DO indeed care. I'll have to give it a try Presumably you mean "as happy" since everything from rotten grapes, fermenting yeast to moonshine makes me happier... for a bit. My theory is that alcohol is a fun shifter. It moves fun from one point in time to another point in time. All fine and dandy, except one problem... there is then a fun deficit somewhere in the future, which will eventually present itself as a hangover.

Everything in moderation, except sailing, which should always be done in excess.

Matt,
Maybe using PVC or whatever they are calling plastic plumbing pipe nowadays isn't a bad idea. It is pretty strong and a lot lighter than 2x4s or pipe. It can be drilled easily to install eyebolts for support. I would probably consider schedule 40 heavy wall pipe.

Maybe you started something.

Agreed. Sch 40 would be the way to go. I think I'll try that! But first things first... I need to fix the seats and install the teak cockpit floor. The boat is in great shape overall, but the cockpit plywood has some rot.

The PVC pipe would snap since the loads are not simple compression. There are significant side pressures dynamically changing as you raise or lower the mast.

[Oswego John]

John,

Oops. Back to the drawing board. Thanks for the info. I never did use PVC but the thought intrigued me. I had always used wood.

Again, thanks.

That was a concern, which is why I thought the additional mid stays would be needed. Has it been tried?

[Steve Laume]

When I read about using PVC pipe it sacred me as well. It only comes in 20' lengths and once it begins to bend it will lose most of it's structural integrity. I would not want to be the one to find out this was not a good idea. Even if it did work once it might not always be the case.

You can get 2X4s, at least 20' long at a decent lumber yard. If you make a tee section out of two for each leg it should be strong enough so as not to worry. Aluminum pipe or angle would also work well. Even though the mast is not extremely heavy it could still cause a lot of damage to itself, the hull, you or all of the aforementioned.

As I always told my kids, be careful, Steve.

My friend bought a 10 foot metal fence post from Lowes and second pipe
I think it was a plumbing pipe about 10 feet
One fit Inside The other
He bore holes and ran a bolt through
I will get all the details

Wood or metal too will lose its structural integrity once it starts to bend. I'm not trying to be argumentative, just not one to dismiss an idea without fact, and thus far nobody has commented that it has been tried and found it to be unsuccessful.

Granted it seems reasonable to assume that Sch 40 plastic pipe would bend under less load than a comparable length of 2x4 or metal pipe, but the idea behind mid stays is to add a bit of additional support mid way up the Gin pole to ensure the PVC does not bend.

Put another way, would 10' of PVC bend sooner under comparable load than 20' of 2x4? That is the engineering question at hand

I like the "one fit in the other" design for compact storage. Any details on what was used would be awesome. Thank you in advance.
