I have come across some old plans for HMB Endeavour which show an arch shaped object under the tiller. Can anyone explain what this is? I'm guessing it could have been marked with degrees for steering and or a supporting run for the tiller?
Notice, not a piece of string. No, it's the tiller on my Sherbourne I'm questioning. The kit's tiller measures 35mm from the rudder top. That equates to 2.24 metres full size, or 88", or 7.3ft. The reason I ask is that I noticed on the original plans what seems to be a companionway at the very rear of the deck. Not so unusual you may say, and I have in fact just built one to the same dimensions. However, measuring the back of the companionway on the plan to the edge of the rudder gives 1.62 metres or 64" or 5'4". That means the rudder would have to be a foot shorter than the dimensions given in the kit to give the helmsman some freedom of movement. It is also shorter than the tiller on the Alert which seems to be 2.56 metres long, or over 8'. I note from the Cutter Trial at the NMM that the tiller on that seems very short from the photo. The actual question is how long a tiller would be on a cutter of this size to allow for freedom of movement as well as strength of leverage? I attach two drawings. The top is from the original plan, the lower is with my inked out tracing of what I take to be companionway and scuttle. If you think I'm wrong about the companionway and that it should just be a scuttle as others have interpreted it, then I'd be glad to be corrected as that leaves plenty of room for the tiller. Another possibility is that I make the scuttle go to the back and the companionway take the place of what I take to be a scuttle. Thanks again, everyone, for tolerating my questions, and I look forward to any answers except 'as long as a piece of string' -- although that may well be closer to the right answser!

Hi again folks, this is more a push than a new question. Another area of research for the Club's build I am trying to clarify is around the Contract specification for a "Lang's emergency tiller". The only information I have found is by the Editor of the Nautical Magazine, Original Papers, January 1836, page 272, makes comment on the Lang ‘Emergency Tiller’ as follows: We understand that Mr. Lang has proposed a plan, which has been adopted, for a tiller, in case of the original one being carried away. A temporary iron tiller is supplied, being fitted to ship in the after part of the rudder above the water, and to be worked by guys leading up to each quarter. To the point: 1. Is anyone aware of an emergency tiller (physical) drawing of this tiller designed by Lang? 2. Has anyone seen an emergency tiller arrangement like this? My current disposition is for a simple iron rod with two eyes, one either side of the arm on the after end which is fitted to the trailing edge of the rudder above the waterline bu means of a slit cut into the end which can be bolted to the rudder as required. However, have bolt holes, even if filled with the bolts until the tiller is fitted, would allow seepage and possible rot in the wood? I have seen no drawings with device fitted permanently.
