i have seen different ways to measure mast rake. my question is when my boat is on the water and i use the hang a weight method is having the weight of my 5hp motor going to throw my boat off its lines. i just feel my boat is sluggish in the stern area when sailing. could this be a different problem or is it because my mast is too far back. |

I have set the mast rake while the boat is on the trailer by leveling the water line with a spirit level by sighting it along the water line and raising or lowering the trailer tongue. When I do it now I use my laser straight line that has a level built in and it puts out a fan beam that shines along the water line. Much easier than on the water.
For what it's worth,

Greg. The answer to your question is yes. The best way is with the boat on a trailer and level. If you have too much weight aft and your transom is dragging in the water then the boat would feel sluggish. Having the mast too far aft would give exessive weather helm. Dick |

Greg,
Another method is to measure the headstay length. I find this an easier method if the boat is trailered (mast down). If you mast is stepped, the the plumb bob method is much easier. A good starting point for the headstay is 27'1" from pin to pin. From there you can adjust it until you have a good amount of weather helm. If you have a kickup rudder and it is not staying down, that'll effect helm. Also, make sure you keel is all the way down. The keel cable should be slack when it is. Some folks like a little tension on the cable, but you should be certain that it is down all the way and then adjust cable tension to you preferences.
Hope that helps more than it complicates! :-)
