Below is a picture of my top. IMHO, especially if you have an outboard, try to keep the top as light as possible, and don't put a big heavy swinging I-beam of a radar antenae up there. Since this picture was taken, I put a small JRC dome up top, and I doubt it weighs more than 20 pounds. A heavy unit up there will make it rock back an forth, especially at rest. Just my outriggers up there, in a beam sea make it roll a little.
