I bumped into an old freind the other day and we got talking and as it turned out hes just got himself a small boat 14ft Bellboy and he asked me a question,which anchor works the best.I told him it depends what the bottom is like,firstly i think i was right(someone correct me if im wrong)the flat type for sandy bottom and the pronged type for rocky or reef bottom. Now with out a sounder to c the bottom his question to me was how do i know what its like down there.Now i really couldnt answer that question except have a look what other ppl are using and gain some local knowledge of the area being fished.Either that or carry both types on board. I only ever used the flat type with a heap of chain on it and had no trouble. So firstly am i correct in the use of the diff types of anchors? Howmany of you carry both types? I was told that you should have at least half the boat length in chain is this correct? Should my freind purchace both types? What type do you use?
