The Custom Self Bailing Whitewater Raft Table from Jack's Plastic Welding Inc.

Why we want to present this information to you in this way:

We do not get out on the river as much as we would like, and we do not assume to be the experts when it comes to whitewater rafting.  However we are the experts when it comes down to design and manufacturing, and we do a better job at listening to our customers than anyone else.  We are giving you this information to enhance the collaboration possibility between those who take rafting very seriously, and JPW who take raft manufacturing very seriously.  With this information, and the information we provide at the general SB raft design page, we feel that we are providing the highest quality information available on self-bailing whitewater raft design.  We think you will find these designs interesting, and exciting to look at. 

Raft designations:

We had to come up with an easy way to designate the different rafts.  The first numbers indicate length in feet.  Then there is the letter K to designate kick of the end.  Asymmetrical tubes will have 2 K numbers because there are 2 different kicks.  This is followed by a d and a number that tells the diameter in inches.  Last there is a b or a w and sometimes both.  The b stands for dimension in inches between the tubes, and the w stands for over all width.

How to get the most out of reading the table:

Pictures are worth a thousand words, 3d interactive graphics can help communicate those words. First take a look at the jpeg pictures that are in the far left column.  This will help give you an idea of where to start.   If you like a design and you want to know more, down load the Edrawings viewer, and then download the E drawing file in the centercolumn of this table to view.  Edrawings allow for real quality collaboration on design because it is a 3 dimensional model in space that you can spin around, and zoom in and out of.  We take our patterns off of these models, and are therefore very close to the real thing.  If you want to read more about edrawings and how they work use this link.

Extra thwart price:

Add 150.00 per thwart for general price conparison. This could be more or less depending on the size of the thwart. for instance Foot thwarts on the inside toward the end need more grommet strip on the main tube, so these little thwarts may cost as much as the larger thwarts.

What the raft numbers mean in the left column where the JPEGS are located.

15L K12 D22 W84 is a designation that means the boat is 15 feet over all length, has a kick of 12 inches, has tube diameters of 22 inches, and an over all width of 84 inches. sometimes we put a designation of B like B 36 would be 36 inches between the tubes.

The dragon fly is a great fly fishing boat because of the extra raise on the floor, the great tracking effect, the hull speed, and low wind profile, and kick provided by the tapered tube design df2011asbl 4659.75 BOATS\Conventional Rafts\dragonfly\Standard DF 2011 but seams rafts\df 2011
