Back to business: paddles

Now that the river skiff is finished, we are turning our attention back to paddles.  More specifically, composite SUP paddles.
The plugs of our designs from Seattle are the guinea pigs for our vacuum bagging learning curve.
During the last few weeks we have made molds of one of the blades and also designed and molded two additional blades.
The newer blades are sleeker and redesigned with input from Hemel.  They are looking for a racing SUP blade with more width at the tip of profile.
Racers like maximum leverage on the water without too deep an immersion.
Here are some photos of what we have been up to...

Seattle / Hemel

Last week I had an Elsah Boat business trip to Seattle to visit and collaborate with Hemel Stand up Paddle Board company's owner and founder, Steve DeKoch.  He is an old friend and coincidentally also has a love of water and watercraft.  His babies are definitely more modern and hi-tech than mine.
His site:
hemelboards.com
My goal with the visit was to learn his proprietary laminate, and vacuum bagging system as well as to design stand up paddle blades for him.
We had a great week of shop work and some great meals in Seattle.
His boards are hollow and made of cored top and bottom panels.  His laminate schedule is very strong and the boards can take some abuse.  Since they do not rely on a solid foam core for structure and strength,  he has no weight penalty.  They are right in their weight class. 
This design prevents small nicks from causing water intrusion which makes standard boards heavy and shortens their life.
During the week, I designed two blades.  The first is a standard blade with a 12 degree ferrule offset.
The second is a high cadence blade for racing.  It has a longer narrower blade.  Both have a triangular cross section.
They are designed to use a carbon fiber shaft.  There will be carbon versions as well as glass versions.
Here are photos of the excursion...

Hemel is located on the water near Fisherman's terminal across from Ballard.


Here is my ferrule for a SUP paddle blade plug in the making.
