commercial kage

so I'm reading the latest online issue of kayak angler and a product review caught my eye. It's a commercial kage made in south florida.

Go here for the makers site: http://deepbluekayakfishing.com/products/

and here's the article: http://www.rapidmedia.com/paddling-newsletters/archive/view/mailid-352/key-95b75bbf3c593276b0146138d4d1827f/subid-70259-5917915e99b5070dc5a5b7a91c8b87f0/tmpl-component.html?utm_source=newsletter_352&utm_medium=email&utm_campaign=video-stalking-reds-kypad-kids-sup-fishy-water-shoes-new-nicer-racks-a-better-kayak-fishing-gaff-new-wilderness-pro-staffers&utm_campaign=website&utm_source=sendgrid.com&utm_medium=email


please remind me; are these legal in WA ?

In WA - gaffs/harpoons only legal for halibut and tuna; or a dogfish if you retain it.
