Christian, Looks to me that all your Ericsons have all become "test beds" for sailing and for that I, and I'm sure for other Ericson owners, we are all grateful because you share the knowledge from your experiences. As for "cockpit canvas", well you're right, it's a matter of personal preference but also, in my case, "marital preference" too! Yes, I'm a married sailor and I'd bet that most wives of sailors, like your wife, prefer to have a dodger protecting their "dews" while sailing along on a windy, rainy or hot day. Mine certainly does even though I have gone over the benefits with her of not having a dodger but as they say, "Happy Wife, happy life." Even though I realize all of the benefits of a boat with little or no cockpit canvas I must confess that I too feel more comfortable with a dodger, bimini (mine cannot be folded down) and yes, even the connect that joins the two. Blame it on my fair 100% Eastern European skin and the fact that I've had cancer twice. Neck cancer once, that had the potential of killing me, which I beat with a rather heavy exposure to surgery, chemo and radiation. The second time it was skin cancer on my nose that require a special surgical technique called "Mohs Surgery".
All that has made me a bit paranoid, to say the least, about sun exposure that I also combat with copious amount of sun screen and large brim sun hats or at least baseball caps. During my bi-yearly visits to my dermatologist he always asks about what I'm doing to protect myself from the sun because he knows that I'm a sailor. So, cockpit canvas is a compromise for me although I'd rather sail without it. But if I must, I try and make it as ascetically pleasing and functional as possible. I've also been thinking of adding some flexible solar panels to the top of the bimini, as long as it's there, to help out the batteries when I anchor for a few days in a row. As for looking up at the sails, which I too often do, I had the canvas maker put an observation "port" in the bimini just about the helm (I'm sure you've seen them) which I eventually replaced with solid plexiglass after the clear plastic window cracked from the sun exposure!
By the way, I absolutely love Brussel sprouts, especially in a nice butter sauce!
