I recently bought my first sail boat with a diesel inboard auxillary engine. The boat is a Pearson 36 with a 30 H.P. Yanmar. After hoisting the sails is the transmission supposed to be left in neutral or in forward gear while sailing? I have reviewed the boats manual and the engine manual and neither one mentions the issue. I have also heard opposing view points from a few other sailors. Is there a right way and if so why.
