I also had a cradle built that was templated to fit the bottom contours of the Whaler. You can see the Whaler in my avatar if you look real close.
I was concerned as you are about the effect of the weight up on the boat deck. I reasoned that it was not much different than having 3 adults up there. But I digress. We live aboard and travel from CT to FL and back each spring and fall. We have had some rough weather at times. The good news is that I don't feel any difference in the handling or stability of the boat. From a physics standpoint I know there must be a difference but I don't feel it. I've been very happy with our set up and love the Whaler.

Howard,
We were just in Stuart and said hello to Karsten and Peggy the day before they left. I didn't see your boat, so I assume you are already on your way north.
Question on Dyneema. Are you happy with it to lift your dinghy. What diameter are you using.
Thanks, Mike

I just sold a 1989 Whaler 11 foot tender (not the sport version). 280 pounds.

Mike: We changed from ss aircraft cable to Dyneema 3 years ago on our hoist/davit and will never use wire again. It's very easy to splice. YouTube has has some good "how to" videos. We went with 1/4". We talked to Nick Jackson, our davit manufacturer, first and his only caution was to make sure you have a minimum of 4 wraps on the hoist drum when it's fully extended because of the slippery nature of the Dyneema.

Since Dyneema is just ridiculously strong, any diameter would work. Generally it will come down to what diameter is the easiest to work with. 1/8" would be plenty strong for your application but too thin and light to be easy to work with. I have 1/4" on my crane and will replace it with the same however 3/16 " would work as well.
Often it is sold in mm so I would look at 6mm line.
