Dan,

Yeah, sure, rotomolding.

A temporary tool (mold) to create the boat, (You are talking a boat here, aren't you?) can be struck from a well prepped, strip built plug with high temperature tooling epoxy and glass. This tool can get you some five or six boats before it craps out. You can have the tool spun (as indicated in the previous response) at any number of shops that do this work on a regular basis.

A real production tool in aluminum is going to set you back about $2000 per running foot for the typical kayak and that means you better have the design very well thought out as well as thoroughly tested before taking the plunge for a production tool.

The result is that you can pump out the Tupperware boats in vast numbers with very high margins of profit. That is if you have the marketing and distribution channels in place to do that work.

My take for production boats.... look into vacu-thermoforming. It's a much better product.
