Looking good Marc! Are the beams on the forecastle and quarter deck the ones to be on the final model? The reason I ask is that they look flat with little round up. If you look at the scantlings for a 32 gun in the The Shipbuilder's Repository 1788 and Steel's The Elements and Practice of Naval Architecture it was substantial. The closest in the Establishments are for scantlings for a 30 gun and these are also shown below. I don't know how much rounding the Marquardt drawings show, that is, did he use scantlings from any of these. Then again, Surprise 1794 was French ship taken by the British, so the round up may have been different.
