Without another adult sized motor your ability to control a 21'x30" boat in wind and waves isn't a whole lot better than a canoe but with another adult you definitely will be able to go places.
Sea socks are a good low weight method to address flotation as a capsized tandem with bulkheads will still take on a huge amount of water compared to a single. A tandem is a good place for an electric bilge pump if you're concerned with the consequences of capsizing. You could turn it into a water cannon for fun.
Most recommendations for reducing weight involve using less epoxy but the trick is to use it where it matters. There's a pretty clear correlation between cosmetic durability and thickness of the fill coats over the glass and under the varnish/paint.
When I say cosmetic durability I mean resistance to water staining intrusion into the wood from dings on edges of coaming,sheer, hatches,etc. Also any water vapor intrusion into the ply through the epoxy from closed compartments or items left sitting against the interior then left to steam in the sun.
Basically multiple thin even coats of epoxy are better than a couple thick ones where the drips and bumps are sanded down.
If you want to go the extra expense s-glass is stronger and more durable than e-glass and damages are confined to a smaller area. Only problem is that it doesn't wet out as clear as e-glass but hulls are a good application for it.
