Slow progress is being made in returning the boat to her former self after the recent unauthorised PNYC clean-out. The main challenge, I’m finding, is missing critical tools to perform simple jobs on board. The stove and base were manufactured in the workshop back in Dirtville but a certain amount of measurement and cutting was required to finalise the supports and hang the assembly in the gimbals. Arriving on board to find no hacksaw in residence almost put paid to the proceedings. I was pretty sure I replaced that saw, the one which was stolen with the rest of the tools but after turning the boat upside down and shaking hard I can safely say I didn’t [not unless I hid it so well that now not even I can find it]. Fortunately my neighbour in the next slip had a half-a-hacksaw-blade in his kit which he kindly donated and I managed to get the bits cut and installed. [It’s not easy gripping half-a-hacksaw-blade]. It still needs some work to pretty it up, varnish the base and the gas hose needs to be properly routed still but for now it functional and at least I can brew a cup of coffee without feeling like I’m camping in the wild.
If one considers all the truly great and useful inventions and innovations in the history of the world, self-steering for your sailboat has to be right up there with the best of them.
There’s nothing much worse than being invisibly shackled to the tiller, watch after watch, day after day, manually steering a course that starts out ok but soon degenerates into an erratic and jagged course across the ocean as boredom and exhaustion set in.
Even on sheltered inland waters, especially when sailing short- or single-handed, the ability to leave the boat to herself while tending the sheets or nipping down below to raid the cooler, is a luxury that, once experienced, will always be high on the wishlist. One might even argue … a necessity even!
There are basically two types – electronic auto-pilots and mechanical wind-vane systems. Both have their place on an ocean-going sailboat.
In confined waterways the wind-vane system will have limited application since any wind shift would quickly put you on a collision course with something. In these situations, the electronic pilots have the upper hand. But they obviously require battery power, which means you need to keep the batteries charged, which means running the motor or installing enough solar or…..and so it snowballs. Anyhow, the average boat would likely have most of the required battery and charging facilities for other needs as well, so it’s likely that a small, low power pilot would be on board.
The biggest problem with the electronic autopilot at sea may well be the sea itself. Electronics and salt water don’t mix and, no matter how well sealed the system, sooner or later it will fail and need repairs. Or the batteries will fail. Or the charging system will host a gremlin or two.
So, for offshore sailing, nothing beats the simplicity and reliability of a mechanical system. There is enough documented experience of wind-vane systems tending the helm for thousands of miles and in all wind strengths. These systems are robust, reliable and long-lived. It’s not unusual to hear of sailors using the same system for 25 years and hundreds of thousands of nautical miles of sailing.
They don’t come cheap however. Delving into this world you start coming up against trim-tab systems, servo-pendulum systems and all the associated theory and speculation as to which system is best and why. It’s fascinating reading a little of the history of how these systems evolved.
There’s plenty of superb gear to be had off the shelf but considering the vast number of different boat shapes and configurations out there, any system will require a fair amount of DIY for installation and set-up. So, it’s not so much of a stretch to move from thoughts of “BUY + DIY” to purely “DIY + DIY”. Here’s a really interesting design concept by Jan Alkema: Self steering for outboard rudders RHM-USD which then lead me to this website which has a wealth of reading material.
Some might consider it strange, all this thought of wind-vane self-steering for a Vaal-based Miura. Others will just understand and believe…! It’s just a matter of time and so here is the new and evolving self-steering research page.

A vessel, apparently, is “every description of watercraft on the water . . . capable of being used as a means of transportation on the water” with the illogical exception of seaplanes, inner tubes, air mattresses, sailboards, and small rafts or flotation devices or toys customarily used by swimmers.
I have finally received my Certificate of Listing. December 2012 the boat was bought and the application made. End July 2013 it arrived in the post. That’s good going, no? Anyhow, the good ship “Tubby” is now officially listed and ….? Well. And nothing really….! Having the piece of paper doesn’t materially affect life [… continued here …]
Sitting here onboard, I hear nothing. Nothing except an owl going “Hoo…..Hooo” that is. Why would I want to be in the Jhb traffic and stress with this on offer I ask ?
The stupidity of the system… Instructions on how to wash your hands in the corporate washroom A lable to warn “Don’t Drink this poison because it’s harmful” COF’s and COC’s etc It’s amazing humanity survived into the 21st century !
The closest I can get to my yacht is a …. tractor ! Ok. Ok. 15W40 is 15W40 right. But I ended up with this one because [no, no, not because of the tractor] my YSB12 manual recommended Shell Rimula. There we go then! –ooOOoo– So, the oil change endeavor experienced a temporary [… continued here …]
There’s a continual temptation in life to cut corners, to do as little as possible, to take the path, that in the short term, seems easier. Take my new backing plates for the cleats intended for the genoa sheets…… I hunted high and low for some stainless offcuts I knew I had lying around. [… continued here …]
