I dont know if it was lack of attention on the leeward port, windward port (looks like there was room to tack but would starboard have missed windward port?), starboard tacker or lack of rules knowlegde.
My thinking is that we have all these rules, and still there are collisions and other infringements. What Gurra wants to try is very simple and would keep everybody focusing on avoiding collisions instead of estimating speeds and headings while analyzing the rules and how they apply before realizing one have put the boat in a really bad situation.
