the regulation is worded pretty weird:

Bows must have a draw weight of atleast 18 kilograms (39.7 lb.) at a draw length of 700 mm ( 27.6 in.) or less.

So essentially, when they draw the bow to 27.6 inches, it must have atleast 39.7 lbs draw weight?

What they are saying they do not want a youth or women hunter with less than 27.5 inch draw length shooting less than 40 lbs.

For every inch below 30 you lose a certain % of your K.E.

Someone shooting a 25 inch d.l at 40 lbs would only have around 25 - 30 lbs of KE....pretty low and likely to wound animals IF not super careful on distance, broadhead choice or shot placement.

I used to shoot a Mathews SQ2 @ 27 inch draw and 72 lb draw weight....but was only creating 57lbs of KE.
 
It is actially an old regulation and relates specifically to recurve and longbows... where draw length stacks the poundage... this is where the term "force draw" came from. With compound bows, consider the weight measured at the peak of the force draw curve, regardless of the draw length, as this will almost certainly take place before 27.5" of draw length.

havent measured arm span yet, but from my height, my draw length will be roughly 27.8 in

so i need a minimum 40 lbs DW to hunt deer?

Yes... your height does not determine your draw length, your arm span is the biggest factor, but your shooting style (open or closed) also has a significant impact.

that clears things up pretty nicely. Thanks
 
Easiest way the measure APPROX. draw length is to draw a tape measure and measure from pad between thumb and forefinger to the corner of your mouth. (with your elbow slightly bent).

That will get you close... +/- 1/2 inch.

Its usually best to shoot a tad bit shorter than too long.
