Well, that doesn't look exactly the same as the German, but it is different from a shipwright.
I found one forum where it was said that there were two meanings of shipwright, one synon. with s-c, the other meaning just a ship builder. The OED doesn't seem to support the first meaning Further on in the forum, a retired sea-man wrote:
"Ship's Carpenters were very common when I first went to sea in the 60s but they are becoming a rare breed now as crews are slimmed down and technology is used to replace them. Apart from the obvious woodworking, timber repairs, dunnage etc. a ship's carpenter was responsible for the anchors and would get involved in actual anchoring procedures and then the cleanliness, securing etc. of them once they were back on board. He also looked after some of the securing of cargo in conjunction with the Chief Officer/Mate and would also be responsible for loading and accounting of fresh water when in port. Fresh water is normally loaded from shore supplies when in port and but made by the engineers when at sea for long periods. Generally a very busy man even on modern ships and I would guess extremely busy in the days of sail.
A shipwright is someone we would meet when in for repairs. This term generally referred to someone involved in the building and repair of ships and boats, based ashore. I've not known anyone actually on a ship referred to as a shipwright but that may have been a possibility in the days of sail. It could be that your man sailed as a ship's carpenter for a number of years and then transferred his skills ashore to ship and boat repair. Many seafarers do come ashore once married and with a young family" (Dennis Harker, http://www.british-genealogy.com/forums/showt...
