[Public-List] Hinged Mast Step Continued

[Don Campbell]

Yves Gelinas has a shorter mast than the factory stick too.  That will 
change both the mass and leverage. I am fairly sure he uses a jib boom made 
out of the spin pole fastened to the mast.
That boat is equipped for ocean sailing with things like 3 reefs in a 12 oz 
cloth for the main. He has it set for big winds and single handing.
His book is now available in English too by the way.

Thanks for the suggestions everyone!
A lot of you don't seem to think it is a good idea...  I looked at the photo 
series of the A-Frame and read the description and to be honest taking the 
mast down that way freaks me out a bit. I guess it is what one is used to: I 
grew up in the Netherlands and am used to tall (over 50 ft) wooden masts on 
a tabernacle. For sure the forces on that are tremendous and you need big 
diameter cables and a winch, but it is possible and although everyone is 
always happy when the stick is back up, it is not a precarious endeavor.
To make it work on the Alberg 30 requires some good planning and the right 
materials. The Ballenger mast steps are quite sturdy and are not "off the 
shelf" items. My suspicion is that they are mostly making them for the boats 
in Santa Cruz. SC has a bridge and I have heard they have boats with masts 
up to 45' have hinged mast steps for that reason. In any case, I will ask 
Ballenger.
Looking at the drawing of Yves Gelinas set up (on capehorn.com) he has some 
hinge in the shrouds, exactly in line with the mast hinge. This is to make 
sure the tension remains more or less the same.
If I understood the comments correctly, some of you seem to think of a 
static A-frame. That is not what I had in mind. Gelinas actually uses his 
spinnaker pole, I was thinking of replacing it with a moving a-frame. When 
the mast is vertical the frame is horizontal (more or less), when the mast 
is horizontal (more or less) the frame is vertical.
Anyway, I will keep thinking about this and ask some more questions to those 
in the know! Obviously, I want to make sure it is a safe system.


Thanks again,


Gerard
