Took a while to figure out how to attach the skis and at either end I've done so with a small angle-bracket. Those at the prow, as here, need to be bent with a mole wrench to match the lie of the hydroski once flexed. Then you'll need to flip the craft over to fix the ski to the bracket with a 4 x 12mm pop-rivet. Use a washer beneath the head of the rivet so as not to penetrate the softer foam core of that skirting-board material.
