Hopefully Sea Sport will answer your question. But foam injected hulls are not always the best way to go. Foaming in tanks often makes them more subject to corrosion, as well as removal when they need to be replaced. Many foams (even those "Closed cell") will adsorb water, and the boat weight will increase to a point of detrimental performance.
Although a Boston Whaler may "float" it may not be a functional vessel. We have towed in several which had filled with water, but the engine would not run, and the people were in various stages of hypothermia.
Personally I would not want a foamed in Tom Cat. I am trying to think how you might sink one--pretty hard to do. They are not subject to the problems which some of the Glacier Bay's have had--either with capsize or hull to deck joint separation.
