Really good fluke anchors are very expensive and almost all are overkill for the AI/TI.
So I agree with Mitch. If you have sand and coral bottoms then the inexpensive grapnel models will work. Get at LEAST the 6 lb version with 4 feet of chain (coated or galvanized). Add stainless shackels to the anchor, the chain and your bow padeye (even if you go with a trolley)
I carry my large folding grapnel anchor/chain to and from the boat in the small hobie dry bag (for cushioning and corrosion protection) but keep 100' of poly line in the front hatch at all times. (This is 2x50' floating lines linked together with stainless clips plus a float). The line stays wrapped neatly on a sturdy plastic electical chord caddy.
I did not add the trolley, cuz with all the fishing lines, sailing lines and tramps, I though it might get in the way. I can snag my lures on enough things as is
If you are fishing structure in sheltered water, the trolley would be handy though.
For temporary anchoring, some folks here use a coated 8-10 dumbbell or hand weight tied to a cheap line. Works great for them and is very fast to deploy and raise.
