Hi André:
I just want it to show you that Im a "TUG LOVER".
Here is one that Im scratched building.
Its calle "Statia Relaint".
This vessel was buit in 2007, by the ZAMOKANA YARDS of the Canary Islands (Hull#658) as the Statia Relaint for the SeaBulk Inland Transportation Company. A foreign operating subsidy of SeaBulk Towing Services Incorporated of Fort Lauderdale, Florida, very close to where I live.
This tug is powered by two, sixteen cylinder, Caterpillar 3516 diesel engines. Turning two NIAIB, fixed pitch propellers, mounted in Kort nozzels to put out 4,000 horspower.
Her electrical services is provided by two, 70kW generators sets. The tug’s capacity are 35,600 gallons of fuel, 1,585 gallons of lube oil, 1300 gallons of oil dispersant, and 6,600 gallons of water.
The towing equipment consist of Iberc Towing Winch, with windlass. 2,2969(ft) of 1.9 (in) towing wire, with tow hook, and a deck crane.
Here is how I started to build her after I found the original blueprints on line.

I have the fittings printed 3-d at Shapeways. I make the designs using PTC elements. A nice working 3-d design program.
Although the drawing of the windlass is rather unclear, I was able to make the following design with some improvisation.
After printing it will look like this on the ship.
I made the sloops from a piece of balsa that was then sanded to shape. Covered with a tarpaulin. I had the davids printed at Shapeways.
The railing is made of 0.8 and 1 mm thick brass rod.
The air scoops are also 3-d printed.
The anchor is also a 3-d product from Shapeways.

Unfortunately, the second test in our pond showed that the metacentric height of the ship is too small and perhaps even negative. In simpler terms, the ship capsizes. Unfortunately, it turns out that this construction method requires too much space within the ship, causing the battery to get too high in the ship. I am going to build a second hull of epoxy with fiberglass using this hull as a mold. I hope it will be okay then.
Hi Andre,
You make a nice progress with your Zwarte Zee. Better a capsize then sinking
. Enough space for some weight.
Regards, Peter

The old hull has now been stripped of the deck and superstructure. The hull was then rubbed about 7 times with release wax to serve as a plug for the new hull to be built. The hull is then constructed from two layers of twill fabric of 300 g / m2 impregnated with epoxy.
The excess glass mat at the top of the hull is cut with a grinding disc on the dremel. After which the struggle to separate the hull from the plug can begin. Despite the release wax, the hull was very attached to the plug.
After an afternoon of tinkering with putty knives and pieces of airplane plywood, which are poked between the hull and the mold, the hull finally succeeds in separating the plug.
Despite the fact that the skin thickness is only 1 mm, the strength of the hull is not that bad for me. Nevertheless, I still glue 15 frames in the hull with epoxy glue.
I coat the hull again with epoxy to hide the glass fabric structure as much as possible.

Happy Birthday, Andre! 
hi love this I got confused, see my dad started scratch building the zwarte zee in 1951. he managed to finish the wooden hull using bread and butter technique. Its 54" long. I recently gave him a billings 1/90th version of zwarte zee but i think its slightly different to version he started building. See pic of his hull and present i gave him recently. Does anyone have earlier plans for 1933 of boat for a 54" length boat OR does someone want to take on finishing my dads original build? If so you can keep the finished model but as long as u let my dad see it sail. look forward to hearing from you wonderful guys and see if we can secretly make my dads dream come true to finish his boat he started 76 years ago!

Spotted this thread while looking for history of the Zwartz Zee. My grandparents have this shadowbox model of the tug which needs some minor repair and I wanted to build some history around it. The model has a small plaque saying souvenir Holland. I think its the 3rd gen tug as my grands probably got it prior to 1948 when they returned to NZ from England. Would love a picture of the 3rd Zwartz Zee to compare
