My Romany is so easy to roll -- and reenter and roll -- that I haven't
bothered attaching bungies for a paddlefloat. Also, I have had no trouble
getting back into the cockpit when I simply hold the paddle, with
paddlefloat, against the coaming. Even though it's a Greenland paddle, it
doesn't move around much once my weight is on it. However, last Sunday I
loosened part of the perimeter line on the foredeck of my Romany so I could 
stick the blade of my Greenland paddle under it. The idea is to use the
paddle to stabilize the boat while refastening the sprayskirt after a
reentry and roll, but it might also stabilize it enough to scramble up on
deck if the reentry and roll fails. The first test will be tomorrow
evening.

Okay, here's what happened. I was going to replace the perimeter line 
anyway, so when I did so, I used enough to allow for some slack between the 
two fittings closest to the cockpit on either side. Out on the lake, I 
inserted one Greenland paddle under the line on either side, so that they 
stuck out at approximate right angles to the boat but angled downward 
somewhat. Then I tried rocking the kayak. Great! -- it was very difficult 
to rock with those stabilizers sticking out.

Next, I decided to try using the paddles to stabilize the kayak while I 
scrambled up on deck after a wet exit. I capsized, did a wet exit, and 
inserted my main paddle under the deck line on the side closest to me. Then 
I flipped the kayak over with the intention of inserting my storm paddle 
under the line on the opposite side. However, flipping the kayak launched 
the first paddle fifteen feet through the air like a harpoon off a throwing 
stick! While Jody Russell recovered the first paddle, I inserted the 
second, then swam around and reinserted the first paddle -- this time with 
the kayak already upright. Because the paddles moved around too much when 
shoved far under the deck line, I adjusted them so only the widest part 
near the tip was under the line. Then I swam up on deck. Once I was up on 
the deck, I overbalanced and capsized again. This time, the paddle slammed 
into the water, and the paddle tip snapped off right where the line had 
crossed it. I finally did a reentry and roll with my storm paddle to 
complete the self-rescue.

Unfortunately, it was my favorite paddle that broke, the one with plastic 
tips joined to it Greenland-fashion with a mortise and tenon. But it was 
the tips that contributed to the break. The tenon in this type of join has 
less cross-sectional area than a solid tip, and on examination I could see 
that the break had started there. Interestingly, the tenon tore out of the 
blade rather than breaking right at the join, as I would have expected (the 
paddle was made of plain-sawn western red cedar). I have more than once 
seen an instructor teach a student to hold the Greenland paddle by the tip 
when extending it, but only once have I seen a Greenlander hold a Greenland 
paddle by the tip, and I believe this weakness is one of the main reasons.

Lessons learned: The original idea of stabilizing the kayak wth the paddles 
after reentry works well, and I think it is quite possible that the paddle 
would not have broken had the tip been solid when I tried the second 
experiment, but I will certainly be more cautious about trying that 
particular experiment again!

Note: The inspiration for this experiment was reading about Greenlanders 
using their paddles in a similar way (only on one side, though, since 
Greenlanders typically do not carry a spare), but I think it was Howard 
Jeffs in England who had the related idea of stabilizing the kayak by 
inserting the halves of a spare paddle into tubes on opposite sides of his 
kayak. My method, like the Greenlanders', has the advantage over Jeffs' in 
that the paddles are more easily removed and restowed.

Ont he Norwegian Canoe Association site there were some very interesting
pictures of paddle stablilized skin on frame kayaks.  Each paddler carried
two full sized paddles.  There were a pair of loops in front of the cockpit 
(one on each side of the boat) and another pair behind the cocpit.  These
loops looked to be 1' to 2" wide.  They appeared to "stand up" above the
perimeter deck line and were just inside of the perimeter lines. The paddle 
was inserted perpendicular to the kayak through one loop until the end of 
the
blade was in the other loop.  This left about 3/4 of the paddle out as an
outrigger.  There were pictures with one kayak stabilized with one paddle,
one kayak stabilized with two paddles (one to each side), and two kayaks
joined together and stabilized using 3 paddles.  I am not sure if there was 
some method of tightening the loops down on the paddles but I would guess
there probably was some way to hold the paddles securely in place.  The use 
of the loops was interesting in that they spread the load out over more of
the paddle than just a deckline would.  In addition the front loops were 
high
enough that the paddle would stay horizontal even though it had to lay on 
the
slightly curved portion of the front deck.  It was interesting that they 
all
carried a full size spare paddle on the front of the kayak.  There was one
picture that had a caption about the ease of getting to the front mounted
spare when you lost a paddle.

The arrangement isn't clear to me from the photos, but it appears that on 
some of the kayaks there might be two pairs of leather straps inboard of 
the gunwale under which the paddles are inserted. The straps are on about 
the highest part of the foredeck, which is not peaked like the Romany's. 
I'm not sure this is a traditional Greenland arrangement. I have the 
impression from reading H.C. Petersen's Skinboats of Greenland that the 
paddle was simply inserted under a tensioning toggle or two, which would be 
a good addition to my Romany for using this technique. FWIW, Petersen 
interviewed several old kayakers, and found that none of them had ever 
heard of anyone carrying a spare paddle. In the photo of the Norwegian 
rescuing another kayaker, the bracing paddle (if it is being used for 
bracing) is inserted under the spare paddle at a right angle to it. I carry 
a storm paddle on my foredeck as my spare paddle, and sometimes I park my 
standard paddle under it in much the same way.

One of the downsides to a wood paddle? Actually with the way you set up the
paddle you created a tremendous force because of the long lever (handle) and
short blade tip on the other side of the fulcrum (the line). Had the paddle
been stronger you may have been able to use this long lever handle to punch
a hole in your boat much like a beer can opener did to a can (before
pop-tops). It is not a good idea to set up any paddle with just a little bit
of the blade under one line.
Cedar is a light wood but unless it has a laminated or very thick (like an
Eskimo paddle) shaft  I wouldn't trust it to do a paddlefloat rescue unless
you knew to be very careful not to put to much weight on the paddle. I
suspect that the tip broke as you started to become unbalanced to that side
and thereby put a tremendous amount of pressure on the short tip forced
against the kayaks deck. Once the tip broke continuing to capsize in that
direction would be hard to stop. With a European paddle the line that you
first put the blade under should not cross the blade but should cross the
(usually) stronger shaft. This also shortens the lever arm available some,
so not as much leverage can be applied to overstress the paddle.
