2 or 3-bladed prop?
I have a fixed two-bladed prop on my 28ft sloop. I''m planning a passage across the South China Sea and am considering switching to a three-bladed prop if that will give me a bit more umpf from my rather enemic 10hp single-cylinder diesel. The trade off, of course, is more resistence under sail. Any thoughts on whether it makes sense to change or to keep it as is ...? Is the trade off worth while? I''m not interested in a folding prop, mainly for $ reasons.
