Proa Sailing: 3 Ply Braided Sennit

September 12, 2012

3 Ply Braided Sennit

From what I can tell, some sennit is laid and some is braided. Usually we see the laid type but here is an NZETC article on Samoan technique showing the braided type and 3 illustrations:

Figure 1 shows the regular sequence

This figure shows one "add-on" sequence

Final figure is another "add-on" sequence

From what I'm gleaning in a quick read this braiding type is good for everyday purposes but is not as good as laid sennit.

About "Proa Sailing"

"The traditional Micronesian outrigger voyaging canoe is a marvel of technological design and evolution which can hardly be improved upon. This site explores concepts for adapting the native rig for single and short-handing. Development is ongoing..."

That's how this site began - to document my attempt to adapt or modify the traditional Micronesian proa sailing rig for the single or short-handed crew.

But now we're evolving...

To what? To be determined... Ode to Proa? All Things Proa? Who knows - let's just have fun with this...

The new byline is Sustainable Seafaring from Oceania. History, Design, and Relevance.

Hopefully I have given credit where credit is due. For all the photos, articles, and thoughts which I've borrowed - thank you to all the authors and photographers out there!

Note: All of the old Star-Rigging research and development postings can be accessed by clicking on the "Star-Rigging" label in the "Labels" cloud below.

The follow-up research, which has been quite rewarding, has its own Page named A Working Crabclaw Sail.

Why tinker with a good thing?

The Micronesian Proa rig is already an exceeding good thing. Why even mess with it? Because single-handing the rig during the shunt can become a daunting prospect as boat size, wind strength, and/or sea state increase.

My traditionally rigged 16 footer was blissfully simple - it didn't even have backstays - only a single shroud. But on a breezy day and on choppy water that rig had a mind of its own when shunting. Dropping down into a trough just as I approached the new bow with the sail was a trip. The whole rig had mass and momentum and went overboard a few times.

As a single-hander I sought a way to get the rig shunted in a controlled fashion - something I could rely on in a breeze and in a larger boat.
