Having done the drawing, a few things emerged...
1/She needed more sea-keeping, just to look right!
2/There was a little more room than I thought, and some spare tonnage.
3/She had the same AA fit as Humelbi, which didn't seem right for a escort vessel, so I added a few!
Also changed the name! (Your thoughts Walter?)
