The British narrowboat canals have locks with seven-foot beams.

Re: I have to have a pedestal made - why not a tabernacle?

Here is Dannys FB page. As you can see he is using a 'modified four-part mechanism' which is based on the Farrier tri folding arms (or vice versa, if you see what I mean).

Danny can probably give you the Excel doc he worked out the 4-part calcs on, but he also notes in his latest that the 4-part system is 2 dimensional, and the 'sheer legs' he is using are in 3-D, so needs some tricky calcs to get the lengths of the arms correct.

This is slightly different to the Telstar system which used 'sheer legs' not attached to the mast. Danny's system is simpler in that the mast becomes part of the 'system'.


It is still in trial phase, but appears to be doing what he hoped it would.

But 42' ought to be wide enough. How wide is Chotu's catamaran?
It’s nowhere near 42ft. Ha ha. That would be quite a boat. I’m 25ft wide.

I’ve researched a lot of the inland limitations and in good even for a lot of the European rivers. I can’t get into the European canals system however.

Thank you for this!

Iíll have a look. Your idea with this system and Telstar really makes the most sense. Right now, Iíll proceed with the simple ďdumbĒ mast step and a crane to rig. Then, I can work out the details of the system some time later.

Can't do some of the Canadian canals either at 25 feet. The Trent Severn and Chambly are off limits (both are 23 feet max beam), but you can do the Rideau (26 foot max beam).
