After doing a pair of new sandbanks, I wanted to do something slightly different but still on the theme of “stuff to crash boats and ships into” and decided on a trio of rocky reef pieces.
As with the sandbars I started with a chunk of .040/1mm plastic sheet, cut it up into three roughly triangular pieces, and carved and sanded the edges down so they met the table smoothly. Then I took some scrap quarter inch cork board, the stuff cheap bulletin boards are made of, and broke it up into crumbs and small pieces for rocks.
It helps to remember that 1″ = 100 feet in 1/1200 scale, or 1mm = 4 feet in scale – so a rock big enough to seriously inconvenience a ship can still be just a few millimeters high! I wanted rocks and islets, not proper islands (those are coming!) so I kept most of the cork bits small, breaking it up with my fingernails as needed.
The bases got my usual blue-green ocean colour while the cork rocks got a black basecoat, and then successive drybrushes of grey-brown, pale grey, and finally just a bit of pure white.
As with the sandbars, I did two coats of gloss varnish over the water parts and then a thick layer of gloss gel for waves, pushed around with a really old brush.
These were almost as quick to create as the sandbars, you use literally crumbs of cork for the rocks so one small piece of cork will go a long, long way, and they look good. I’m looking forward to seeing them on the table menacing players who forget that no matter how dangerous the enemy is, the sea is even more deadly and far, far more unforgiving!
