Introduction

The 1970 report described the Arade 1 shipwreck hanging from the upper part of the embankment created by the dredging works, and filled with 1 to 1.5 m of sediment. The frames were 13 x 16 cm in section, the room and space between 16 and 35 cm. The hull planking was 5 cm thick and varied between 25 and 34 cm in width. The ceiling covered both the lower part of the hull, and its sides - the sketch showing no stringers - and was terminated with a series of filler pieces that closed the room between futtocks, as shown in FPAS' pictures.

There was a large keelson - or mast step - preserved at least along 5 m. It was surmounted by a rather small keel in the sketch by Mr. Albuquerque. According to the report a large part of the ship was torn apart by the dredge and laid scattered on the seabed. It is possible that the falling sediment quickly covered this part of the ship during the following weeks, as the embankment, originally cut at a 1/6 inclination, re-arranged itself into a more stable slope.

A wood sample taken by Mr. Helder Mendes was sent to Groningen, in the Netherlands, and was dated by radiocarbon to the 13th century. As this date is not calibrated, and we do not know exactly where the wood sample was taken, it must be taken very carefully. Another sample - probably from the planking - was sent by Mr. Farrajota to Laboratório Nacional de Engenharia Civil, for species identification, and was found to be from a tree of the oak family (Quercus sp.).

The pictures taken by the FPAS team show a very interesting feature. It seems that the upper ceiling strake is a stringer, thicker than the one that lies below it. The pictures taken by the CPAS team were given to us by Mrs. Margarita Farrajota, the director of that diving club in 2002. She kindly let us see her notes and took on the work of assigning captions to each one of the 18 pictures lent to us, based upon her notes and sketches, placing them on the hull remains as they were seen at the time.
