Apologies for delay, but I have only just come across your query. The Dell Quay brand have been manufactured by a succession of boat builders, the last I am aware of was Fletcher Sportboats - who brought the 'Rights' from RTK Marine in Poole. The hull and deck were placed in a massive jig and the foam pumped in under high pressure to achieve the correct density - without the jig the hull and deck would be pushed apart. Unfortunately, deck fittings, handrails etc. allowed the ingress of moisture and eventually the foam become saturated, leading to added weight and a subsequent loss in performance. A simple test was to walk around the deck and if there was any give or bulge then avoid that craft. The work you are undertaking will provide bouyancy, but without a jig and commercial foam injectors, you will never achieve equivalent reserve buoyancy and hull rigidity. However, whilst you will never be able to emulate the bouyancy and rigidity of a manufactured craft, I cannot see why you should not be able to provide a safe fishing platform.
