This was not true. Neither the designers, builders, nor owners of the TITANIC EVER said it was "unsinkable"! It is a MYTH!!! It was a pervasive "story" that was started by a newspaper reporter, when the advantages of the 3/4 height bulkheads were being explained. The ship was built of steel
, a decidedly NON buoyant material.
Regarding our Searunner
however... If you look at a copy of The Searunner
Construction Manuel you will find a photo
of a large Searunner dangling from a crane. The entire bottom of ALL THREE hulls are missing and you can look up at the sky! It had been repeatedly rammed by an angry whale, never sank, and while mostly awash, it made it back to the dock
to later be rebuilt.
This was the old Searunners... (25,31, 37, & 40) They either had metal non buoyant connectives, (25 or 31), or they had wings that were open from the main hull
to the amas for additional storage
. Even THEN, they were unsinkable.
The 34 however, (like we have), was designed many years later, as an answer to: "how can we improve Searunners"? Unlike the others, the wings are totally sealed, and broken up into many separate air void compartments. I have 8, "o" ring deck
plates, to inspect these voids.
Now, it is not only unsinkable, but floats NOT totally awash, and in mild conditions, could continue "down wind" on it's way. VERY slowly of coarse. Upside down, with the amas' air locks, she bobs like a cork!
is weightless in an awash boat, all fuels actually float, as do the cushions
, jugs, fenders, and much of the boat's contents. Only the engine
, batteries, and tools continue to weigh something in an awash boat.
This is NOT like a FRP boat. Our hull
material itself is naturally buoyant, many times over more so than the weight of the 600 or so pounds of non floating contents... And this would be true, even with 500 holes in it!
Our 34, with it's sealed wings, is many times over more buoyant that in the previous case above. It floats @ the cockpit
sole if totally awash, OR upside down.
The crew has been known to survive as long as three months in an upside down trimaran
. "The story of the Rosey Noel".
So, while fire, or cold water
, could easily make this safety
feature a moot point... Regarding hitting containers, in normal seas & warm climate, it gives me peace of mind. If any one of the hulls were holed, I would goop up a scrap of plywood
, nail it into place, pump out the hull, and resume on my way. This sort of thing has been done MANY times.
I don't think that our unsinkable trimaran
, OR the ETAK unsinkable monohull
, OR a submarine door bulkhead "flood resistant" monohull
, makes us invulnerable to the perils of the sea by any means, and I didn't mean to imply that it did. There are a LOT of ways to die at sea!
My boat's "unsinkable nature", just like a solid foam surfboard, is, however, a fact, NOT just a claim made by an ignorant reporter trying to sell papers with exaggerated headlines.
The subject was containers... The risk of, etc. My suggestion, weather
it is with one hull or several, is to have an ace in the hole, (no pun intended). Something like: An unsinkable hull material, buoyancy compartments, automatic air bags, or a "submarine door" bow bulkhead. To one degree or the other, it helps to alieve "that sinking feeling".
