You need a port, starboard plus an all round white. First challenge is the all round should be 1m above the P&S. With no A-frame that means putting it on a pole (can be removable) on the console or transom.

Maybe with a longer pole?
The P&S - why can't they go on the console? They are far from ideal there but would be legal. You can get some nice little recessed ones that go on the sides of the console...

There are temporary options available, but they may not actually comply with the law for visibility etc. Crawling home at 3 knots in a SIB you might be fine. Doing 30kts WOT - you may come foul of a harbour master... Clip on boat light navigation LED marine battery powered sail canoe kayak dingy | eBay

But I'd want my white higher up as it will bleach out the colour.
