I have no idea of the type of conditions you experience in the Pacific North West, but if your vessel is over forty feet might I suggest you already have a good spare
anchor. What you do not have is an adequate bower
anchor capable of holding you firmly and safely while riding out a storm. My vessel is a light trimaran weighing about seven or eight tons loaded--and my main bower
anchor is a 60 pounds Manson on 100 metres of short link chain--with a further hundred metres of 20mm hard nylon
rode to follow that of the water depth necessitates it. I get to sleep soundly at night when at
anchor--but I do use an anchor release rope and float in case it does foul something on the bottom. In reef waters we have some things that take big bites and tiny things with fatal stings.
