Item) There are no currently available kits of the Cyclone-class PC in plastic or resin. There may be a bare fiberglass hull available in the RC scales. .
Item) The Floating Drydock offers plans of the Cyclone-class. These are General Arrangement plans and do not include hull lines. Getting an accurate hull shape from GA plans is rather tricky.

The builders plans (Bu-series) they list are rather limited subjects. The G-series is more complete.
Item) The Canadian Iroquois destroyer shown, or any destroyer for that matter, is significantly different from the Cyclone-class patrol craft.. Start with one of them and you would do just as well as starting from scratch with a stock of bass wood, plexiglas, and Evergreen (Oh yes , and a good set of plans!).
Darren at Resin Shipyard does good work -- but the product suggested will not work
