I was sailing back from Rakino island to Auckland the other day, not a long way but a few hours sailing. My old self-steering is broken (and being redesigned), but I kinda wanted not to sit at the tiller for the whole time.

Also, I had recently read a voyage for madmen everyone started out with self steering gear, but only Bernard Moitessier's didn't break. The others, that managed to stay in the race long enough for their self steering system to run out of spare parts, just had to get their boats to sail were they wanted them to go without it.

They managed! That inspired me to try this other technique again: sheet to tiller steering.

Okay, we are sailing on the quarter - that means behind and around 45 degrees to one side. The boat isn't very stable in this heading, so we need something to adjust the rudder. The only means of input here is sheet tension. When the wind is in the sails, the sheets are tight. feed that to the rudder. When the sheets are tight, turn down wind, if we turn down too much, the jib enters the wind shadow of the main, and the jib sheets will loosen.


I just tied a rope onto the sheets like this, it then went through a block at the other side of the boat, and then to the tiller.


That turns the boat down, but we need something to balance that, to turn the boat back up when it turns down too much. But we don't need a sail this time, we can just use something elastic!


It actually worked surprisingly well! that is to say, my expectations were quite low. but it meant I could make hot chocolate and read more of walkaway while it took me home.

I think the conditions where quite good for this at the time. It was a steady wind, and not too strong. If the wind and waves were stronger there is more chance it might push the boat out of the range this system can balance it self in.

If you're feeling arduino-ey i am gonna leave a Simrad TP32 with fried electronics at hackland (but good motor and hall effect sensor), slap a LSM303 and a motor driver on that bad boy and you will be sorted.

This week in Scuttlebutt

A sample of life in the Scuttleverse.

There are currently 28 people helping to fund the future of Scuttlebutt through the SSB consortium!

Totally Random

@MattMcKegg climbed a hill and shared a spontaneous outdoor synth jam.

@Alanna found a butt

and then another mushroom butt of another variety, but you'll have to find that one on your own.

@Dominic's self-steering rig is broken, so they tried some old-school "self steering" techniques on a recent trip.


@Modante shared some pictures of their quincho being built.

@frankiebee says

i'm going to take you on a 6 to 8 day adventure of making cocoa nibs! mmmmm nibs

cocoa pods

@Powersource was shown the emoji pair for Solarpunk

@xxssxx shared some hedgehoggy goodness.


@mix is

... interested in whether it's possible to build apps (desktop / mobile) on the scuttlebutt stack which I can sell

This is a thought experiment for the moment, but I think it's useful to explore because it's going to get increasingly relevant, especially with the release of MMMMM.

@Zach! shared some Good Information Zines

example cover for zine showing ryland, dressed well, looking up with confident wonder and the words 'good information about snakes' written in bubbly font

@iBob shared a short tale of loud swallows, quiet owls, and moths.
