Why is the Portland Pudgy rotation-molded polyethylene?
The hard polyethylene shell is tough, durable and is not subject to deterioration or puncture. At the same time, the material has flex, which gives it greater impact resistance than fiberglass, for example. The polyethylene, which is inherently buoyant, is formed as a double hull, the lower portion of which is filled with a closed-cell foam. Polyethylene is resistant to marine growth.
