Any success stories to share with regards to installing a solar extraction vent? Or tips to increase ventilation?
Yep. I replaced the dorade vent on the coachroof with a solar vent set to extract, and I leave a couple of the aft cabin hatches on vent, and since then have had no black-spot at all and the boat doesn't smell musty when you first open it up any more.
Which make and model? Did you need to alter the coach roof?
Chinese vent from ebay. About £40. I had to enlarge the hole in the coachroof as the solar vent is slightly larger than the dorade vent.
Taped a plastic bag over the inside of the hole and then used sanding wheels on a power drill.
I have mounted a computer fan on a rectangle of acrylic plastic the same shape as a rutgerson opening port. This just slips into the galley/ cockpit port when the port is opened. It is connected to the solar panels that I use for battery charging. It uses diddly sqat of power and runs all daylight hours . I have used it now for 15years and it is very effective for the long suffering cook. Geoff

Blowing in or out?
Generally blowing out , but if wanted just pop it in the other way round. Geoff

Yes, I put one in (https://www.force4.co.uk/force-4-solarvent-300s.html) and it worked really well, keeping the inside musty-free. However, after a couple of years the seal around the solarpanel started leaking and destroyed the electrics so I wouldn't buy another without sealing it with an extra layer of goo. Recommended, with that caveat.
I like your idea, Geoff.
