The S4 is very lightweight (just 98 lbs) for what it offers.
This is not much even in comparison to many fishing kayaks, and it’s very little compared to skiffs. Which is why a fisherman standing on the casting platform at the bow of the S4 causes its stern to come up, and its bow to go down.
This is not that much of an issue for fishers who use their S4 as skiffs (namely motorized), or in tandem with a heavy paddler sitting at the rear, and in a full skiff capacity, namely with both another crew member and a good size outboard motor.
With both a motor and a fishing buddy at the rear, the S4 front casting platform is perfectly level.
For those who fish alone from their S4 without motorizing it, and prefer to cast standing on top of the front platform, here is a simple, easy, and lightweight solution –
Use 3/8″ plywood to extend the front casting platform backward, onto the front part of the cockpit.
This can be done while having the board rest on top of the saddle, or on top of the coaming (spray deflector), as seen in these images:
An angler standing on top of such platform extension will be stable, and the platform level.
