18′ SeaCraft Project

The beginning of a new project we are working on here at CBC. This picture is from the cavity of an 18′ SeaCraft . Let’s play a game here…name the problem!

If you guessed rotten fuel damage, ding ding ding, you are correct! This was mainly due to corrosion to the gas tank, which was also the original gas tank in the boat. This is what Timmy came across when he removed the center console revealing the top of the gas tank. Pretty gnarly huh?

The outside of the tank had never been treated leading to massive corrosion, mold, 150 pounds of excessive weight and lots of damage.

Fuel/water was leaking outside of the tank and saturating the foam surrounding it.

Tim pulled out all the gas/water saturated foam,rotten fuel fillerand vent hoses, and the existing 30 gallon tank  and cleaned out the cavity thoroughly to prep and install a new 50 gallon gas tank. He fit the new tank (a “dry run”), then removed and ttreated it with Alumiprep and Alodine to provide good paint adhesion. The tank now awaits several coats of anti-corrosion paint.

 As you can see in this picture, not only was everything cleaned and new parts installed, but the tank itself will be moved forward when all is said and done. Tim fabricated and installed a support for the front end of the tank which will be slid in a total of 16″ underneath the forward deck. This shifts the front of the tank a total of 36″ forward of where it used to be.  The other great aspect of this is if this gas tank ever needed to be worked on again (which it won’t be unless Mr. California runs it hard aground ;] ) the console is moved just enough to place the main deck panel beneath it, therefore you will be able to remove the gas tank WITHOUT removing the console!  How cool is that?!

Another bonus for the customer is the previous hatch that covered the bilge pump was inoperable and a down right pain. The scuppers were high and the hatch just would not stay sealed, this led to the boat sinking, not only once but twice due to the constant still water. The hatch was also very small so working on the bilge was incredibly time-consuming.  So Tim will now install a new bigger, water tight hatch so the bilge is accessible after Kevin raises the transom and deck and installs new scuppers. This will prevent the “splash over” in reverse and on the mooring that was such a problem with this boat and excellent drainage. No more standing water on deck!

Not only is it more convenient to have it built this way, but also the boat performance itself will only be enhanced. This shift will center the boat so it will also sit better on the water, the only thing that will make this boat absolutely perfect is a nice, beautiful fuel-efficient Honda 4-Stroke Engine.

    Hey Sam and Tim,
    Great work and great blog! There is one factual error, however; the boat has ONLY “sunk” once and in fact it never technically sunk, rather it merely “turtled.” Key distinction I like to make. Thanks again!
