Hello Zoltan, Your Santa Maria is looking very good. I know I have caused you enough grief with the rudder already and I hate to say more, but I think the pintles(strap with the pin) should be on the rudder and the gudgeons(straps with the eye) on the stern post. Unless your plans show different, and I then apologise, that is how I have seen it normally done. Some ships have a pintle at the top of the rudder and one at the bottom of the stern post, in this case the pintles are much longer.
Sorry to be a pain
