I've seen two basic types-
One type where the cutter is on a wire or rod that travels up an down a cylindrical slot in the keel's leading edge. Cons: there's a slot in your keel, the cable jams or gets bunged up, the slot is fragile. Pros: they work great and are always ready to go "right now", when they're not bunged up.
And the type where the cutter is deployed from the end of a steel shaft that is inserted through a tube inside he boat, next to the keel. Cons: gotta go downstairs, pull the dummy plug, insert the knife tube, push it down, deploy the knife, cut the kelp, then reverse the steps to un-deploy. More "english" involved in cutting the kelp- it takes practice to get the right feel. Need to store the knife tube. Need to fabricate or buy the knife tube. Pros: nothing but a flush plug on the exterior skin of the boat, no keel slot, nothing attached to the keel at all.
With a small boat like this, it may be pretty effective to just learn to back down and get back to speed quickly.
