We did the bow chat. What about the stern? I love what it does for  
the handling and passive propulsion of my S&G baidarka when in a  
following sea. So much so that some friends and I did a group build  
on a double.

Would a commercial kayak benefit from a baidarka stern without the  
bifid bow?  Would customers run screaming from the showroom if  
presented with such an offering? Would a kayak with a regular bow and  
a baidarka stern result in ridiculous broaching in a following sea?

I don't think that a greenland bow and a baidarka stern are that
incompatable. When I look at the stern of a Mariner Express/Sprite/Coaster
and compare it to a baidarka stern they look mightly similar. And it does
the same thing for my Express that it does for your S&G baidarka in a
following sea... however Matt and Cam put a nice skeg on the Express to help
keep it from broaching too quickly.

Didn't Wilderness make one those in plastic awhile back?

The whole thread of "will a baidarka bow/stern work on
a modern kayak" entirely ignores the fact that the
baidarkas these ends were put on were very flexible
along their longitudinal axis.  This is critical to
their functionality.  Yes they will broach
riduculously when applied to a rigid hull; no they
won't when applied to a flexible hull.  Why wouldn't
an orange rind work on an apple. . . .? ;-)

I don't understand this, probably due to complete lack of any experience
with a baidarka, but...
Why does a flexible boat with a blade at its stern not broach, but a rigid
boat with such a stern broach ridiculously?
I would guess a baidarka stern would hold the stern a little in a following
sea, and allow the bow to swing down-wave, and that would happen whether the
boat has flex or not.
What actually happens with a replica baidarka?

Dear Peter, 
First, any kayak will broach given the right
conditions, so excuse my hyperbole.  The "blade at the
stern" is not the key element I had in mind-- its the
wide truncated stern; essentialy a highly buoyant mass
right at the stern.  In a following wave, this buoyant
stern will get lifted quite easily which will cause a
tendency for the bow to submerge.  This tendency for
the bow to get submerged (adding to the potential of
broaching) is dampened considerably with a
longitudinally flexible hull (pitching specifically). 
With a flexible hull, the stern can get lifted without
the bow being forced under.   It is merely "less of a
tendency"-- using 'riducously' was hyperbole, borrowed
from a previous post.

Briefly, they tend to snake over the water's surface
instead of lunging and plunging into and over waves. 
Is it better?  I'm not sure-- it may have some
drawbacks and it may have some advantages.  It is
however a very interesting sensation and challenges
many a concept of how a vessel interacts with dynamic
conditions.
Best, 
Harvey

subject: [Paddlewise] Valley hatch flange repair
Date: Sat, 1 Sep 2007 20:43:49 -0600
I'm looking for suggestions on how to repair/replace the 16"x9" hatch 
flange on a VCP Skerray RMX.  There is a 2-3" vertical crack along 
the long edge of the flange at the point where the vertical portion 
of the flange meets the horizontal base.  I was thinking about using 
small SS screws to hold it together, but but have no idea as to what 
adhesive / glue to use (the flange appears to be some sort of 
plastic).

Thanks, Brian
