Butting decking boards over a joist

Hi everyone

I'm in the process of building a deck off the side of a pool - joists are 200 x 50 hardwood, decking boards are spotted gum 136 x 32 (superdeck) and i'm using type 17, 14 gauge stainless batten screws to hold it down. Not sure how to butt together 2 decking boards over a joist. Four 14 gauge screws over a width of 50mm (offset of course) will be crowded and could split the joist, and the screws will end up very close to the end of the decking boards.

Apart from wider joists, are there any solutions out there?

Cheers, Scott

There are 3 options i think.. Nail or screw a piece of offcut to the joist so you have 100mm to screw to (50mm each piece of deck)
Skew screw at about 30deg angle into the edge of the joist or

Cut the boards at 45deg and overlap on the joist and you can just use 2 screws through both pieces of decking.
