Before I start-loved your post on fixing engines-What a hoot.!!
Re your query on the keel.
Maybe I should start again with this.
They call me " He who knoweth nought about keels "!!
Your dead right it does not have a " fin keel ".That's what I called it though .At present it is simply a 5/8 inch thick ( I think ? ) steel
plate running along/into the bottom of the hull.Full length most of the way at heights ranging from approx 1.1 mtr near the rudder
then dropping down to 200mm at front.
What I was thinking of doing was welding rail at 90 degree right angles to the 5/8" plate along the length.Probably could manage to fit 1x 7mtr length plus 1x 5 mtr length along the plate on each side
of the plate below the hull at lowest point possible.
This would give me a total of approx 1400 kilos rail weight. The boat was approx 9 tonne when taken out to put on the hardstand
.I know it can be done welding wise but just not sure of the practicality.It should maybe not present a great deal of drag because of the low cross section when sailing.
Maybe this idea is too far out there and doesn't make any sense.?
Anyway, it is just a thought at present and I am keen to get opinions.
If it all seems like a "pie in the sky" idea in the end I will go to a normal boxed in type keel ( not full length though ),use the rail and other steel
punchings and concrete it all.
Will gladly take other suggestions .After all I have plenty of 5mm steel plate to play with.
I am really interested in types of keel design and in general just want to understand the dynamics.
My aim would be to not have to rely on a lot of crew as you say.
Thanks very much for your comments.
