does anybody know if i't worth the work to fair the aft end of a mainship 1 keel?
Fairing the keel is without doubt worth the effort. I did tha job on my ex Mainship 1. Just from that alone I gained 250 rpm at WOT and you can do the math what that means thru the entire rpm range. I was able to add 2 inches of pitch and still spin up to proper rpm and then some.
It is a very simple project that takes maybe 6 or 8 hours worth of labor. I made my fairing bullet shaped.
Mule, that was me and I thought the rudder was fine but I guess that's a matter of opinion.
By the way you can witness and perhaps prove to yourself as I did how the fairing will help. I did this one driveway at home during a rainstorm. While the water was running downhill I took a 2x10 and used it to dam up the water just the the flat end keel on the Mainship. I was amazed how much the water was displaced as it went around the board. It really upset the water flow. I was convinced a fairing would help.
Just to be clear.....before pix....
