New Old Paddle

 03 Sep 23:

I found an old paddle in a junk shop last year, and planned to repair it. After tripping over it for a year we decided it was too long and that we could cut it down to a shorter length, trim the blade to a Greenland shape and make it a paddle suitable for a wee lass and/or Sunfish cockpit.


The shaft is about an inch wide so I cut a 12 inch long diagonal scarf in two spots, to remove some of the length.


Next I marked the centerline of the blade, with plans to trim off one edge to match the narrowers side. I'll also cut off the damaged end of the blade.

Small Boat Crickle

02 Dec 18:

From the minds that brought you the Padook, a combination Greenland paddle and boat hook, springs the Crickle, a cricket bat shaped paddle for small small boat usage. We credit our friend Chris for recognizing the similarity to a cricket bat. The design impetus for the Crickle was the need to have a paddle on a very small boat, like a Sunfish or Sailfish, where there is limited real estate to stow it when not in use. The small paddle would be used to get out of the wind shadow of a tree line, a few quick strokes to paddle through a tack in a light wind, and for use when the wind dies. It can also be used to fend off boarders.

We had a few paddles laying around, neither one of these floated our boat.


We first tried making a short paddle, short enough to fit in a Sunfish cockpit, with a big, conventional blade. Took it out for Sea Trials and found it still took up too much space, and was not easy to control one handed. It probably would be good for a longer distance when the wind dies, two handed. About that time we received our first Greenland paddle, and while marveling at the blade design we wondered if it would work on a short paddle. We made Crickle Version 1.0 from a white pine 2x4, easy to shape, cheap, available and floats well.

Cut the 2x4 to length, which is a secret.


Marked centerlines for the paddle shape and trimmed the handle down to 1 1/2 inches per side, the dimensional measurement of the "2 inch" side of the 2x4 as it turns out. Used the table saw to cut most of it then cut the handle neck with a jigsaw. The desired blade shape will be a symmetrical ellipse, similar to a symmetrical wing on an airplane.


Marked a round tip with a highly calibrated template and fine precision Sharpie.


Marked centerlines of handle, to be used as guides for the Stanley #51 spokeshave.


Rough shaped the paddle with a Kobalt power planer, smoothed it with the spoke shave and Stanley #5 Jack plane, and finished it off with 120 grit on a DeWalt random orbital sander. Shaved the spoke shaped handle with...you guessed it...the spokeshave. Compare the Crickle blade size to the Greenland blade, we put the handle not quite halfway down so we could put one hand there as a fixed hinge point by our hip and use the top grip hand to work the paddle back and forth with a light grip.


We tried it first on our AMF Sunfish SUGAR 2, it did what we hoped it would do and lived happily on the cockpit floor. Lightweight and easy to get out of the way. It could also be carried by the splashguard. The motion is more of a sweep than a dig, that


Tried it out next on the Alcort Super Sailfish ZSA ZSA, I used it to paddle 250 feet out from the shore to the light ripples on the water, used it on a lazy tack and then paddled back in another 250 feet when I was done. The paddle sat secure next to the handrails but some other means of securing it like a lanyard (we called those dummy cords in the Marines).





The Crickle is just under 3 feet.




Potential design variation is to add a boat hook, which would change the name to Padooklet (trademark claim).

Mini Greenland Paddle for Sunfish

15 Aug 18:

We have been enjoying our new Greenland paddle from Shaw and Tenney...I say ours, Skipper loves it and won't let me near it. Found out it works good as an SUP paddle as well. We also have been playing around with paddle design for our Sunfish, wanting a paddle that fits in the cockpit but is not the aluminum/plastic telescope model. We made a short handle paddle and it was okay, but I made it out of live oak so it is heavy. And it needs about a quarter inch planed off of it.

So anyway, we were wondering if a mini version of the Greenland blade would work, something under 3 feet. Traced out the cut lines on a piece of cypress and went to work. Cut the sides with a table saw, then shaped the face of the paddle with a power planer. Final shaping was with Stanley #51 spoke shave and random orbital sander.

Marked to 3 inch width.


Centers for handle.


Centers for blade.


Tip shape.


So what we ended up with looks a little like a cricket bat. I meant to make the hand grip wider like the BLAIR paddle, but got excited and cut too much off.



Sea Trials for the paddle, it did what it was intended to do and I didn't feel that I lost anything with the different blade shape. I paddled through a few tacks in the light wind and simulated getting the boat to and from the shore in light wind conditions. The grip could have been bigger but the paddle is so small and lightweight that it didn't really matter. The Greenland blade shape slipped through the water with ease, so a lot of force was not needed on the grip. The flare from the handle to the blade was in a good spot, a comfortable pivot point out by the gunwale.



Thinking about a 3 footer now that is all blade, so we can paddle the Sunfish kayak style!
