Main thoughts
I am totally new to this blog so hopefully I am in the right place asking the right person or persons. I have had a 1978 Ericson 35 with an overall displacement of I believe about 11,500 pounds and a "swept fin" keel of about 5,000 pounds. It has the original mast and the basic sail plan is a Full North Main and a 135 roller furling jib.
I am almost 70 and would like to keep sailing as long as I can. I love almost everything about the boat except its tenderness– When it gets about 15 or 16 kn, I have to reduce sail area and I want to know if anyone has modified their keel, for example with a lead boot superimposed on the existing keel to make it a stiffer rig? I am going to consult a naval architect but wanted to get feedback from existing owners as to whether this has been successfully tried before.
Thank you for any help you can provide and I'm not sure if I look for responses in my personal email or here. If you want to respond to my personal email it is

I am about two years older than you, and yup I do have less energy for this stuff than I did twenty years ago. Having said that I would not want to change over to a slow or inefficient sailboat design that needed 15 kts just to start sailing.
EY built good performing boats.
About your keel-- no real way to attach a "shoe" to the bottom due to having internal ballast. I could do that to ours (external lead fin keel) if I had enough $$, and have sort of considered doing it to reduce the draft from 6' to about 5'. Spending about $10K. to do that is not in our budget!
The root of the problem, as I read it, is that your boat is heeling unacceptably in true winds of 15 knots -- and above. Considering your boat's very healthy ballast ratio, I would agree with the experts that it's really time to reef. Our boat is lighter and has less ballast than yours and we need a reef at around 18 to 20 true.
It's been a long time since your hull left the builder and the original rigger. I would also hazard a guess that the original reefing gear is in need of a full upgrade. Old sheaves and blocks might be sticking or just plain inefficiently located.
And then there is another factor to consider in a boat that has been through one or multiples of prior owners -- sails.
I do not know the condition of your sails, especially the main, but I do know that a main that is well-used and stretched will usually cause heeling due to 1) too much belly from stretching, and 2) that shape will have migrated aft as the material stretched over the years/decades.
Further, if the prior owner had installed a new main in recent past, he may have chosen to have a maximum-draft shape done to enhance lighter air racing. Such a shape is often not so much fun for general recreational sailing. So, if the sail cloth is in good condition, a recut will often reduce heel with minimal $ outlay. Any good loft can do this, and a good loft will also not be afraid to tell a potential customer to put the potential recut expenditure towards a new main if the present one is too marginal in condition.

Just for comparison and illustration, Iif you look at our boat in the picture in reply 32 in this thread, our full main is trimmed out pretty "flat" that evening and this photo was taken in about 12 to 15 kts true.
Best of luck in getting to flatter sailing and maximum velocity!
