Martha Jane and ballast
Hello Bolgerites. I've been out of town for four weeks and off the list. I
got back yesterday and perused the messages on the website and was surprised
that the new martha jane design in MAIB did not draw much comment at all!
Maybe we burned ourselves out last spring? For my part I like the upgrades
and will be starting the new rudders and the sponsons in a couple of weeks.
If anyone else is doing the same I'd be interested.
I did notice a short exchange between Col and Ed re. ballast. I appreciate
the lightness of the new mast that you have Ed. My spin on the ballast is a
bit different from yours however. I found the graphs on stability and
righting ability most interesting- as I read those graphs the ballast is a
real key factor in the ability of the new design to self -right. The sponsons
and high house together will create the ability to self right - but the
difference the ballast creates is dramatic. I currently have 825 lbs of
ballast and intend to go to the full 1000 lbs. I like the difference the
increased ballast has created and would not under any circumstances consider
less than I now have.
