I have a Freedom 2-28 (28''cat-ketch with a full length keel) which is extremely poor at backing down. The present prop is a fixed two bladed model which has considerable drag and collects more than its fair share of kelp.
Would changing to a three bladed prop help reduce any or all of these problems? Another option is changing to a folding propeller - either two or three bladed. Aside from the cost, are there any significant disadvantages to a folding prop?What model or manufacturer do you recommend? Thanks.
