I didn't want to drill into my new yak yet so clip on anchor trolley. The trolley is removable/ reconfigure to put the anchor where it is needed.
Step 1: Parts
Rope/Paracord (who doesn't have some about)
2 spring carabiners (got mine free)
1 figure 9 carabiner (got a bigger one than what i had)
1 split ring/ other metal ring (keyring works)
1 Anchor/weight/brick (otherwise this is pointless)
Step 2: Trolley Loop
The ring is where the anchor line passes through. To keep tension one end is static with a fixed hitch and the other is an adjustable taut line hitch.
Step 3: Front/Stern Loop Ends
The rear carabiner is simple.
Step 4: Setting the Anchor Depth
the figure 9 can also act as a pulley to raise the anchor. other knot-less devices can be used or fast hitches.
Step 5: Go Fishing
