Anchoring is not hard, but there are some elements that must be accounted for... Enough Rope...You want a 7-1 ratio of rope to depth for optimal holding, so if you want to anchor in 14ft of depth, you need 100ft of rope. You can get away with less, but the right amount of rope will ensure a good angle of attack for the anchor, and thus, more holding power. A chunk of chain will help with the angle of attack also. I suggest a generous anchor, generous chain, and generous rope. watch the boat while at anchor picking a fixed point as reference so you can quickly identify if you are dragging anchor or otherwise not staying in place. Watch some anchoring videos. Wind direction and position of other boats is important. Boats already anchored will be facing the wind if they are on a single anchor.
Once you pick a spot you like ... (Not on top of other people if you can help it...)
Drive Into the wind past the spot a few boat lengths depending on depth of place the deeper it is, the more rope you need to release. 3-5 boat lengths normally works out.
Place Anchor in the water (with chain and rope attached, and bitter end tied to the boat)
reverse into place, front of boat into winds and waves...give rope as requested by anchor, slowing tug to help set here and there
Make sure Anchor is holding the boat. Some recommend tie off and reverse for a few seconds to make sure anchor is well set and does not move, not a bad idea.
Once you feel confident all is well, and boat is not moving from there...then,and only then turn off engines.
If anchor does not hold, there is no shame in that, maybe landed on a crappy spot, or something is tangled... pull anchor up, and try again.
Wrong way:
Pick Spot
Turn off boat
Throw Anchor
Tie Rope
Pray
Start boat again when you start hitting other boaters because you are dragging the anchor.
When departing...
Turn ON engines FIRST!
Retrieve Anchor, using boat power to help the anchor retriever dude or dudette
All Set.
Wrong Way:
Pull Up Anchor
Can't start boat
Crap, now drifting out of control
Eventually boat started after great comic/horror show for other boaters, (tragic/comic depending on their proximity to you.)
There is so much more you will learn. It's an exciting and fun hobby. Read as much as you can, and get a demo ride and/or someone with some boating experience to help you if available...You don't know what you don't know, but you learn quick!!!
I realized too late you said "new to Jet Boating", so this may all be familiar to you if you come from an non-jet boat. Oh well, already wrote it so It's staying. Best of luck, take pictures!
