Hello All,
I'm new to these forums, having recently purchased a 1982 shoal draft E38 from forum member John Butler. Among other modifications I'm considering is adding Mars Metals (MM) "stability bulbs" to the foot of the keel. I have contacted MM for their recommendations, as I'm sure they have manufactured bulbs for the same model boat in the past (see attached photos previously posted by rwthomas1)
Alas, the company responded that they haven't kept the old designs and need specific design parameters from me before they can quote.
All that said, does anyone know how much weight would be appropriate to add to the bottom of the keel to improve the boat's stability? For some reason, I'm thinking 300 lbs per side (600 lbs total), and that's a guess with zero engineering to back it up.
Thanks so much,
Vaughan
