The person sail

1 Jan

It’s the turn of the year, and I thought about doing all sorts of different things for this blog post; an origin story, a story about Douglas’s death, something meaningful in one way or another to mark the new year. But actually, I’ve decided instead to show you another idea that Douglas had. Some of the scans of the pencil drawings are not very clear, my apologies but it’s the best my scanner can do. My first sighting was on this page here:

person-windsurf-rough-sketches

See that sketch on the right? It turns up again here:

human-wind-surf-rough-sketchesIt looks to me like a sail, with a person lying underneath it. The notes read ‘operates in best @snorkel depths’ and ‘pre-shaped sail.’ Here’s another one (it’s faint, apologies for the very poor copy):

fish-and-sail

It’s tricky to see, but you can make out a fish at the top. The note reads ‘sail fish (kind of)’ and then underneath is a person in the same position, arms outstretched to the left, just under a water line. The arrow points to a mast. The title reads ‘La Grandella Beach Tues 15th June 04’ so this is clearly a little light holiday sketching.  The idea took hold, and he worked it up more thoroughly:

person-with-sail

The notes begin to show his thought process, including ideas for the mechanics and things to think about; ‘the mast is sprung loaded’, ‘using a ring pull to raise it’, ‘is that how wind surf works?’. ‘Try a simple fixed sail first’. ‘A lighter person would mean that it travelled faster’. Questions include, ‘will it work without a keel?’

By 3rd July, he’s worked it out a bit more:

person-sail-notesThe note on the right shows doubt: ‘This probably won’t work  If it does it may slowly  It will take some/a lot of power to move the human body under water’ but he’s added a keel filled with stones, a fibre glass mast, and noted that ‘the swimmer may have to rest stomach in’. The development continues the next day:

person-sail-notes-more

He’s started thinking about the maths: ‘at this stage do not know area of sail, approx 1m high’, and added controls to the handles ‘the grips work like a fishing line they twist the cord tightens and loosens to control the sail’. The tick on the right suggests that he likes it.

Finally, he does a proper drawing:

sail

He’s added steering gear (on the drawing on the right, beneath the handles bars) and more notes ‘bending mast with sail’, ‘scalloped sails’ s/s wire rope link’,’wrong (more fin area)’ but there it is, a person sail. As far as I know, this is as far as this idea went, although I may well be wrong. Happy New Year!
