Hi:

we used to set our fist class mast placing the boat between two other sailing boats, with masts high enough, and with their halyards raise it (we knot the halyards a little above the center of gravity of the mast) and place it.

Excuse me for the english.

 As Cifrian says, place the boat between two other minis, and raise the mas with their mainsail halyards... seemed pretty easy to do. Haven't done it personally yet, but saw it a lot of times...

I have placed the mast in my proto a number of times using what we call here in the US, a "gin pole". Basically it is an aluminum mast section that is about 7 meters long...the base of the pole is placed on the foredeck and then a rope headstay and sidestays are rigged. A line through a Harken block at the top of the gin pole is then used to hoist up the mast.

Hallo Andreas,

habe bei a.w.niemeyer folgendes gesehen (wird bei Folkebooten eingesetzt):

   
AWN Multilift-System
Dieses neuartige System ist mobil und macht sie unabhängig von Kran und einer vielköpfigen helfenden Crew! Feste Konstruktionen werden überflüssig - das klappbare Teleskopgestell lässt sich ausserdem platzsparend verstauen. Vergessen Sie Mastkran-Termine und Warteschleifen im Hafen! Endlich können Sie unabhängig Ihren Mast setzen und legen, wann und wo Sie wollen. Der große Vorteil des neuen Systems: auch durchgesteckte Masten lassen sich ohne große Hilfe sicher und gerade ziehen. Feste und lästige Jütt-Konstruktionen an Deck sind überflüssig, das neuartige Sys-tem ist mobil und lässt sich leicht an Deck oder an Land lagern. Zwei mit einem Klappmechanismus verbundene Teleskop-Rohre werden mittels Achter- und Bugleinen an Deck fest aufgestellt, an diesem Gestell wird der Mast mit einer Talje bewegt. Die Länge lässt sich dem optimalen Hebepunkt anpassen. Das erhöht die Sicherheit und macht das Handling leichter. Der mögliche Hub beträgt 6,50 m bei einem maximalen Rigggewicht von ca. 120 kg. Zusammengeschoben messen die Teleskop-Rohre nur ca. 2,6 m. Ohne Talje.


Artikelnummer: 310409

Preis: 319,00 EUR

Thank you !
It seems the "gin-pole" is more a good idea with a mast thats not going through the deck ? It have to be 2 poles, right ? The mast has to swing somewhere...

The AWN system is originally from COMPASS (http://www.compass24.de/cgi-bin/abnetshop.pl?ARTNR=112540) and seems a good tool. 299,- Euros,..a bit cheaper than AWN.

In my harbour I would have to pay 230 (!!!) Euros to take the mast down with the little crane... (boat is on a trailer with stepped mast..)

Thank you very much all !

Andreas

For Echells and j24s the typical gin pole setup is a chunk of broken mast that reaches slightly higher than the distance from the mast bottom to the spreaders (single spreader rigs). It is only one pole so as the mast is lifted off the deck and out of the deck opening the bottom of the mast is pushed to one side and then lowered. This means it ends up slightly crooked on the deck but not so much as to be a problem.
On Brossard in the TransAt, I think he used his bow sprit in the same fashion to restep his rig after the forestay chainplate failed and it fell down.

Andreas,

Gin Pole is single pole triangulated with line to front and sides of boat. Then lifting line to mast and lift away. With mini masts being light, I lay the base of mast forward and swing into place as the rest of the mast is raised.

whoooo,...sounds good. I might try that. I will find a piece of mast somewhere and tie some ropes to the top of it,... in as many directions as possible to stabilize it. And then tie a block to the top and lift the mast out. Need lots of ropes to be on the save side. Boat is on a trailer. High up and a bit shaky...

Andreas,

Not sure why it is call that, guess the original designer of the pole was drinking Gin and got brave enough to try it to lift something.

Gin pole is use to assemble radio towers, my first exposure to using one.

Ok, this is starting to get interesting.  Maybe the solution to this problem should be a required for all mini  sailors.
For one, you also have the boom,  then you have the main sheet and various blocks, you have the bow sprit,  you have seemingly miles of rope, line, etc., you have a big roll of duct  tape (or should have), you have various winches all over the place, and now you have a bottle of  gin.  If you  can't figure out  a way to put your mast up by yourself, maybe you should  not go out  on the ocean  alone.
Just play around with it a little  bit and you will  find  it is  not very hard  to do. Have fun.

Sorry, I did not mean one should not ask questions on this forum.  I think it is the best place around to find good information.

With that in mind:  Once the mast is in place or using a similar boat, write down and keep the measurements of each shroud and stay. That way you can make up a replacement that works quickly.

Hello everybody !

1st : Thanks to all who have answered to my questions !
2nd : It works !!!

I wasn't keen to pay 230,- (!!!) Euros in Port Pin Rolland for using the mast-crane only 10 minutes. So I told myself
I HAVE TO find another solution. I found an old Dinghy mast with all the wires still connected to it and with the
help of a friend I managed to upright this Gin-Pole-Mast on my boat which was standing on the trailer already. The gin-pole
was to long. I guess 6,5 Meter would be enough. So we opened the hatch and poked it through the opening using a
piece of wood to prevent scratches inside. This gave me another possibility to fix the mast at deck-level and make
it even more stabil. After the Shrouds where fixed it seemed rock-solid and we attached a rope and started lifting.
To our surprise it was very smooth and easy ! The mast came out easily and it seemed even less risky than a crane because
the boat wasn't drifting. I was first worrying about the distance between the pole and the mast. The mast could have gone the
wrong direction when pulling it up. But for some reason it just went fine !

Cheers !
