Shipping is not built into the cost of Expandacraft.
International shipping, go to http://myus.com for a quote.
The following calculator will give you a rough estimate to ship an Expandacraft within the continental United States. It is based on sending 6 hull parts, so it works for a 12 foot paddlecat or a 12 foot outrigger kit for 2 sides.
Note that the calculator is an estimate only, and we will get you an actual real shipping quote after you buy and invoice you for the actual shipping cost.
