"What is the hull composed of?"
OK, I'll bite.
ummm, what is snips and snails and puppy dog tails? . :mrgreen:
Do I win????
Well ectually (british accent on that) it is solid fiberglass.
I am not aware of a single tug out of the hundreds built, having issues with the hull.
I have had mine in water it should not have been in where the contents, including the people, were thoroughly homogenized and hurled into the companionway. Amongst the din of green water crashing on the top of the pilot house and pots and pans and cans of food mixing together, I could not detect the slightest sound of distress in the hull. The engine was ticking over at 1200 rpm to give me steering and when after two and a half hours we finally got into the lee of a point, the boat hummed along as serene as if it had just crossed a duck pond. Lake Superior was thoroughly annoyed with us after all that effort.
The thru-hull fittings are properly bedded and I have not heard of problems with leaks from any owner on this forum (which is most of them).
There cannot be water intrusion into the core as there is no core - just solid glass.
But be aware that any and every yacht ever built will have thru-hull leaks someday. And this includes multimillion dollar Flemings, Kady Krogens, yadda, yadda. Of course, the cure is simple. At about ten years unscrew the thru-hull and replace the now dry bedding compound with fresh goo. Good for another ten.
If it is a tug you do it yourself. If it is a Fleming, you will sit in the cockpit with a fresh martini (shaken not stirred) listening to Rigoletto as the 'help' beds the thru-hulls.
Now as far as the deck, windows, etc. I cannot give as glowing a report. Their have been leaks during heavy rainstorms on some boats. All are solvable. I have done mine. But I hasten to note, that for a hand built product our Tugs have vanishingly few complaints - compared to even high end yachts. And Ranger is the industry model for factory response if there is an issue.
Will you be happy with a Tug. Dunno (shrug) since I don't know you.
But I can tell you that there is no other pocket yacht that you can throw onto a trailer and haul off to Alaska (Roam) on a mere whim, or off to Yellowstone Lake for the summer (several on here), or off to Florida for the winter (dozens on here, including the Charlotte Ann being prepped for her fourth trip)
