I do like combination sweeper/layers: they appeal to my sense of humour. She seems quite quick for her size and type, but I don't know if there's some doctrinal reason for that - defensive minelaying and sweeping only really needs 8-12 knots, whilst offensive work would need destroyer-type speeds, at least for a layer.
She's also got quite marginal stability, and an awful lot of residual strength. I'd suggest reducing hull depth to mitigate these problems; you might well be able to take 50-100 tons off with careful sizing.

I'm not happy with the stability either. I'm still new to Springsharp - which parameter, or parameters, impact hull depth? The 180 tons miscellaneous was just a SWAG.

Hull depth is treated in a slightly odd way in SpringSharp: normally, you'd select a depth, calculate weights and such, and then find the draught (hence freeboard) corresponding to it. In SpringSharp, you specify draught and freeboard, and the depth is the sum of the two; to cut depth, you'd want to reduce one or the other.
180 tons probably is a bit on the high side for sweeping gear; ISTR that adding sweeps to the River-class frigates entailed an addition of about 50 tons. That'll all be on the main deck, so cutting back there would be good for your topweight and improve stability, although maybe not right back to the 50 ton figure.
I may try to write a short article in the next couple of weeks on naval architecture as applied to SpringSharp, and how to design a ship, if people are interested.
