Getting steamed up...
Just a quickie for those who have been following, and taking sides on, our
bottom project. Yesterday we had a steam cleaner (8GPM @ 3000psi @ 225°F) clean the bottom of the boat. Target was to assure that any diluted runoff from our removal of the acrylic Poli-Glow from the topsides didn't adhere to the raw fiberglass which we'll be adhering new glass patching in the deep spots, fairing with epoxy material in all the rest, and then 30-mil epoxy barrier coating before bottom paint. Secondary target was to prove out our modus in removing blister potentials. Recall that we had been advised to thoroughly wet the raw hull, with as much pressure as could be mustered, frequently, and then PW off any resultant exudant (and, of course, chase same with grinding). There were many places in the beginning, getting fewer each time we did it. So, we have now done the extreme of volume, pressure, and heat. Before this, in the intervening month we were away from the boat, it was kept wet very thoroughly as our topsides compounding was under way. We've seen no weeps of solubles from any of the areas on the bottom, despite it having been a month to accumulate the potential, and in the recent past as we attacked the issue of uncatalyzed water-soluble materials in the original layup. Hoping of course, but not yet proven (until now) that such Pressure-Volume-Heat process would both force high temp water into anything which would accept it, and, then, of course, run out, more effectively than just ambient temps, along with drying more quickly due to the elevated temps, as well as expose any insecure bonding of layers at the points we'd ground. A day later, there isn't the first sign of a weep, and aside from some very small (1/8" max length) feather edges of prior epoxy top-offs of blister repairs which were blown up on the pressure, not the first lifting of any laminates or surfaces, either. All the pressure has raised a very small amount of what Lydia calls "baby bird" effect, that of slight protruding hairs - but that will only serve to increase adhesion as we put on the fairing compound and barrier coats. So, I believe this reasonably proves the thesis that the way to dry out a "wet" hull is to put water on it, the hotter the better. That we've had the luxury of followup on the first attempts (which DID expose additional areas needing attention), and to continue to keep it wet, for a couple of months helps. However, it hardly needs the "couple of years in a shed" routine which, in itself, if the thesis is correct (and it certainly appears so), is actually non-productive to the desired end result (removal of as much as possible of the WSMs in the layup). That we've removed any reasonable level of available WSMs from the hull, following up with not only epoxy fairing but a very thick barrier coat, we feel, should put this blister issue to rest. Even if it doesn't, we're not going there again in our lifetime :{)) L8R Skip -- Morgan 461 #2 SV Flying Pig KI4MPC See our galleries at www.justpickone.org/skip/gallery !

Steam has to be at more than 1000 F to reach such pressures. If you pressurize steam to 3000 psi it will condense unless very hot. The liquid in question will begin flash into steam as it leaves the sprayer tip. It might not be properly called steam cleaning, but I admit that is a nitpick. In my experience, steam cleaning uses just steam. Casady |

You don't know what a low end boat is. There was a Brit with a duffle bag boat. He wanted to see San Francisco, so he sailed it there, and the canvas never blistered, for that matter. Paid for 186 pounds when he went through the Ditch. He wrote a book. Casady |

It'll also cause any trapped moisture to boil out causing more holes and tiny fractures into which sea water may ingress to cause further blisters later on. This new 'drying out' method advocated by Skippy and a few other fools in this group is just so destructive. Makes me wonder why ANYONE, even morons, are stupid enough to believe it. Wilbur Hubbard |

You are welcome to take a Fol-bot around the horn, against the wind, but it won't prove you are a sailor, rather a complete nut. If you want some nutball sailing take a sunfish out when it is gusting to 40 and more, I did that once. I used to sail the Iowa Schooner,20 foot gaff rigged, and I know what a sailor is, although I don't claim to be another Wm Bligh. Casady |

Since you include yourself in that statement can you enthrall us with an account of your voyage "round the horn". As I said previously, you do have some entertainment value, albeit very little.
