Hi Mark

You raise some interesting questions. I spent some time considering sitting
position and cockpit depth earlier in the year when designing and making a
stitch-n-glue kayak. Its a mystery to me why any one would want to build a
kayak with a deck up to your armpits.

There are some pictures of my boat at:

http://www.abdn.ac.uk/~ltu006/images/stitchnglue/

I based my cockpit on the pintail ocean cockpit, which if I remember
correctly has a depth of about 11 inches. I felt however that the pintail
had a wee bit too much volume for my interest, but the sitting position
relative to cockpit rim, knee bracing under the foredeck and rear deck was
pretty much what I was after - relatively flat legs against the underside of
the deck compared to knees up and wide white water style bracing. The  glass
seat (at least in the pintail I borrowed for a couple of weeks to take
measurements) is positioned quite high at about 2 inches from the keel, so I
built my deck to give a lower  depth of nine and a half inches at the front
of the cockpit, and about half an inch lower at the rear, but fitted my seat
as low as possible to give me essentially the same sitting and bracing
position as the pintail but with reduced volume. Consider the seat height as
well as the cockpit/deck volume/beam as factors influencing the stroke.

If you are interested in valley pintail/avocet I would recommend making the
trip and test paddling them, both are really nice boats, but its worth
noting that the deck/volume sitting position is somewhat different in the
ocean cockpit and key-hole cockpit pintail - if you are going to test
paddle, try them both if possible. The relatively wide beam of the pintail
to my mind also feels to be slightly out of character with the rest of the
boat. If you are looking for a surf boat / sea kayak, then take a look at
http://www.radicalmoves.com/

Radical moves make surf kayaks but they also produce a sea boat called the
sea squirt, which may well be exactly what you are after. Its top of my list
of boats I'd like to paddle.

Re greenland paddling style, I wouldn't claim to have any great authority on
the subject
but what Greg Stamer says makes a lot of sense. I vary the angle of the
stroke and I don't get too hung up on keeping it low for the sake of keeping
it low, the beauty of greenland paddles is their versatility. I also don't
think that there is necessarily any 'proper' stroke - I think that more
important than trying to keep the stroke low per say is sensitivity to what
the blade is doing, particularly the angle of attack of the blade, and feel
and feedback from the blade during different strokes.

Mark,

I have the same problem. I am 5'11" and 170 pounds and find that the
current commercial offerings of "pseudo SW Greenland kayaks" are simply too
big and fat for my tastes. I have always wondered why 21 inches is
considered "narrow" in the current kayak market. Perhaps designers fear
that anything smaller would appeal to such a small group of paddlers to be
a worthwhile return on investment. It's enough to either make you either
buy a surf-ski or consider making your own kayak.

In my opinion, if you really want to plunge headfirst into advanced
Greenland-style techniques then your best bet is to make your own
skin-on-frame kayak (and your own paddles). I recommend H.C. Petersen's
"Instruction in Kayak Building"
<http://www.atuagkat.gl/booksonsale/mar99/art.htm> in conjunction with the
two articles on "Building a Greenland kayak" by Chris Cunningham, Winter
1992/Spring 1993 (contact Sea Kayaker for reprints).

I have paddled an Anas Acuta for ten years (small cockpit) and was fairly
happy with this kayak until I had the use of Maligiaq's rolling kayak for
six months in 1998 (shown in Rolling with Maligiaq) and the use of his 17"
wide "racing" kayak at this year's Greenland championships. Although my
Anas Acuta is 20.5" wide, it looked like a barge when beached next to
Maligiaq's rolling kayak. Even a kayak such as a Betsie Bay Recluse, which
team member Cindy Cole took to Greenland to compete, was quite large
compared to an authentic skin-boat sized for someone of my dimensions.

Many of the advanced Greenland rolls require very low volume, and even the
Anas has much more volume than I need, especially in the foredeck. As far
as commercial kayaks go, Maligiaq Padilla liked the Romany and Pintail and
found them slightly easier to roll than the Anas. The Anas does have hard
chines that make certain other techniques, like the balance brace and side
sculling, easier. If I had to buy a new commercial kayak then my (current)
personal favorite is Nigel Foster's Silhouette as it works quite well for
many Greenland-style techniques although it is not as maneuverable as the
Anas Acuta or Pintail. YMMV, give them all a try and formulate your own
conclusions.

Too much beam and volume can easily affect your stroke as well as your
ability to perform traditional maneuvers. Some of the effects will be
obvious (such as busting your knuckles) and others will not be so apparent.
For example, if the kayak is too wide and you pad the sides of the seat,
then you will find that the hip pads keep your weight suspended high above
the water when the kayak is on its side. This will make skills such as the
balance brace, side sculling and the Petrussen maneuver more difficult. The
Greenlanders often perform an abdominal crunch on each stroke when they
sprint, similar to a situp, made possible by the low masik/thighbrace (the
sensation is similar to having someone hold your legs during a situp). The
high foredeck of commercial kayaks creates too much knee bend to use this
technique in the traditional style unless you seriously pad the underside
of the deck and then you will still have to deal with the excess volume
that interferes with advanced rolling techniques (traditional hand rolls,
sculling with the paddle held under the kayak, etc).

On the other hand, it is possible that the trouble with your stroke may not
necessarily be caused by the kayak. Keep in mind that if you build a
Greenland-style paddle to most of the current literature, the instructions
often assume that your kayak is not much wider than your hips. If this
assumption is not valid then you will have to increase the length of the
paddle shaft to accommodate the width of the kayak to avoid leaving
remnants of your knuckles on the foredeck.

Also, your stroke may indeed be too low. American Greenland-style paddlers are
obsessed with keeping the stroke as low as possible. In Greenland the
stroke varies between very low for slow touring to a high, vertical stroke
for maximum power and speed. During both the 2 mile sprint race and the 10
mile long distance race at the Greenland championships, all of the top
paddlers used a high stroke with their narrow paddles. In addition to using
legs and body rotation most of the paddlers allowed their pushing hand to
rise to shoulder level and punch forward (crossing the centerline) using a
strong push-pull component that is common with "Euro" technique but is
usually totally absent from American Greenland-style paddlers. Even with a
high stroke, the elbows point downward and are kept fairly close to the
torso, but are not "glued" to the torso. The strokes are long and flowing
with the paddle exiting behind the hip, much different than the
short-choppy stroke that I usually see being taught in the States. Many of
the paddlers also used the forward tilting blade technique, as recently
described in Sea Kayaker, but this was not universal.

Regarding surfing, I much prefer to play in my surf kayak and wave ski than
in a sea kayak. If you are looking for a maneuverable sea kayak that still
is fairly good at Greenland-style techniques then the Anas Acuta, Pintail
and Romany (among others) would all be choices for you to consider.

Mark Arnold asked: <SNIP>
>>>>6. What are the cockpit depths for the Valley Pintail and
Avocet?<<<<SNIP>

I have 12" for both, but these aren't measurements I did myself so they may
be total depth rather than inside cockpit depth, but I don't know that for
sure. Also, a German magazine listed the Pintail at 11.4" (29cm).

Our original kayak was 20.5" wide. Now the narrowest is 21.5" wide. I too
like the performance and handling of Nigel Foster's Silhouette, Shadow, and
Legend so when I finally got the chance to become a dealer 3.5 years ago I
jumped at it.  The Silhouettes' have helped teach me that as a retailer (as
well as, as a designer) I have to pay attention at least as much to what my
customers will buy as I do to what I personally like. I've still got two
Silhouettes w/skegs in stock that I have had for nearly 3 years now (even
though the prices are now down to less than wholesale on them). Anybody want
to make me an offer? I almost traded one for a well used Titanium Mtn. Bike
a few months ago. If Cam and I could have agreed on which hand worked which
brake on a bike (or who got the bike) we would have probably made the trade.
Got to run off to Nigel's birthday party now, bye.
