Parker21, I had a very early Robalo 20 (not the 19) built at the Sanford factory and had a larger (original offered was 60) 100 ga tank installed. Largest engine available then was a 135, as I recall, which is what we installed, along with a bracket and "come home" kicker. Still often ran with extra 6 gallon tanks tied down. Had one of the first T Tops built with the outriggers on top, was the first T Top I ever saw at that time. Used it in the Gulf and often stupidly ran wayyy too far offshore with it to fish. The south end (Chicken Neck) of the Middle Grounds was a favorite area, as an example. Buried the bow many times coming home with both the large bow hatches filled with Grouper and Snaps. Boat was very good at self bailing so did keep the deck clean. We were in a kinda "recession/depression then, and my previous job went away. We needed money, had a pretty cool boat, and catching fish was EZ then, even with the very unreliable Buck Rogers type Loran A, it was no problem loading the boat with catches that qualify as PC incorrect today. Then, we sold the fish and paid the bills. Long story short, the 20 was a well built and nice to look at, for its era. It had a shallow deadrise resulting in having to slow down in a chop. It was also a bit wet. The foaming technology was fairly iffy then and I later saw several 20s with bulges on the insides where the foam expanded too much as it cured and may have soaked up some water as well. Moved on to numerous other boats, commercial and pleasure ( 23 SeaCraft, 31 Ocean Master, 231 Mako and several larger custom diesels and others) both new built and restored. You might consider looking hard at other, newer boats that benefit from newer materials, technology (especially better hull designs) UNLESS you have deep pockets, lotsa spare time and mucho boatbuilding knowledge. You will have $5-10 K in an old 20 sooo fast and still have a kinda bumpy, wet, pretty boat. You can get a pretty little boat that turns heads and rides well pretty darn cheap these days, that requires little work or $. You may not get the "personal ego gratification" of having done it all yourself, but take your family or a kid out instead on a ready to run boat with all that time. Boy, Im getting old. Im the guy that has rebuilt quite a few "pretty" boats, and have the receipts to prove it. Good luck to you Jim. Jim
