Prior to mid 2011 we captured technologies with potential applications to virtual propeller guards (sensor based guards) or to conventional boat propeller guards on our Technologies page, now titled Prop Guard Technologies <2011. With the advent of our new site, we are moving future posts of this nature to their own category which we are launching today (March 25, 2012). Our earlier information on potential Propeller Guard Technologies will remain on the old <2011 page. Some of these technologies may have application to other guarding applications as well.
