Tiller Damage and Repair

For some time, I had been aware that my tiller--a laminated mahogany/ash stock tiller manufactured by H&L Marine that I purchased new in 2001--was not in the greatest shape.  The glue used in these manufactured tillers tends to let go between the laminations over time, and I had seen signs of this.  Also, the glue failure was exacerbated by the fact that I had drilled a large hole into the tiller in order to install my tiller extension housing., which of course allowed water in through the top.  I wasn't too concerned about it, as I planned to build a new tiller over the coming off-season anyway.

At some point, I replaced the screws holding the tiller extension, since the originals were stripped.  (The tiller extension puts a fair strain on the tiller when in use, especially on aggressive beats where the weather helm is significant.  I always steer with the extension--it just feels wrong without it, to me.)  The larger screws seemed to be the kiss of death, and a small split began to form shortly thereafter.

I didn't want to replace the tiller, since I wanted to build my own during the winter.  But I needed to be able to use the extension, so obviously I'd have to do something since the current situation was unworkable.  I didn't particularly care about the existing tiller--it could make a decent second spare (I have the original, too), so the type of repair was not important as long as it worked.

Back on the mooring, I removed the tiller from the tiller head and replaced it, temporarily, with the original solid oak tiller that came with the boat.  This allowed me to tie the rudder securely, as I always do.  Plus, I could still use the boat, though I'd enjoy myself less with the old tiller.  I brought the "new" tiller home with me for a quick repair.
