Hi Nathan, forget styrene cement use Plastic Weld

Place two pieces of plastic together and using small paint brush apply weld to joint.
Use Zap two part Z-poxy resin either 5min or 30min setting time.

Mix equal quantities of epoxy and hardener.

The styrene cement in the tube does have its uses as well (running a fillet on a seam), as does cyano (sticking some of the fiddly bits).
The most important things to remember are
1/ There shall be no holes below the waterline.
2/ Any seams below the waterline shall remain intact.
There are plenty of other things, but they mostly affect appearance and performance, which are both secondary to keeping the boat on top of the water.

Styrene glue can be homemade from Methyl Ethyl Ketone (MEK), which is available in hardware stores (paint dept.) in the US for about $9 a quart. Put a few ounces in a glass jelly jar or a metal can with a screw lid, make a hole in the lid just big enough for a small brush to enter and screw the lid on tight (MEK evaporates very quickly if not contained). Make a tight fitting plug for the small hole. Cut some scrap styrene into tiny pieces and drop it in the jar. The MEK will dissolve the styrene. This gives it a bit of consistency and a small gap-filling ability. Apply it like someone else on this thread said, with a small brush. Fit the parts together and tape them in place before applying the cement, because it melts the styrene and sets in about 20 seconds. It is dry and hard in an hour or less.
This is not my idea. It came in the instructions for my Model Slipways Loyal fleet tender. I have built the whole boat with this stuff, where styrene-to-styrene joints are made.
