Anchor recommendations

[For Steve]

What would be a suitable anchor set-up for temporary anchoring of a 4m tinnie in about 10m depth on rubble and reef bottom in Moreton Bay?

Recommendations of anchor type and size, and chain length and size would be much appreciated.

Regards

For general use I'd say about 4m of chain 6-8mm and a small plough.
Whatever is the cheapest to replace I reckon. Should know I just left my second one for the year on the bottom on Friday night. A dear one too. Took my own advice and grabbed a cheap plough today.

Thanks Brendan. Will you be tripping the plough? Would tripping my sand anchor be just as good?

Brad, give us the GPS coordinates of that spot you want to anchor over. I've got a 'Best Anchor Selection' software program on my putter & it'll spit the answer out in no time. Alternatively this link is useful for background info.... http://www.bluemoment.com/anchorrodes.html

A lot depends on the conditions, tide run, drift, wind, swell. If it's howling you probably wouldn't be fishing but here's an option that might give you some chance of holding position in the worst case, which should mean in conditions good for dropping a bait it could be an over kill - at least 50m x 3 core silver rope 8mm to 12mm (personally I prefer 3 core nylon, 100m x 10mm), a meter of 6mm to 8mm chain (short or long link) per meter of boat lenth (6mm should be sufficient), reef anchor (see pic below). A Danforth or Sarca anchor might also hold depending on bottom conditions & what the weather is doing to your boat on the surface, but a reef anchor would be first choice. Personally I use rated shackles to join anchor to chain & chain to rope (the rode) vice cheep charlie shackles, & then use stainless wire to lock the shackle pins. The pins will eventually vibrate free othewise & then end up donating your gear to Davey Jones. Just check that the shackle head can fit through the chain link. An anchor float/puller is a helpful bit of kit to help lift your anchor vice pulling it up by hand. You may need to carry two (at least types of anchors). Could also consider a drogue or mini-sea anchor to slow your drift as a fishing aid vice anchoring. There are also some handy ways to modify the chain attachment to a plough or danforth with cable ties to assist in lifting them if they get stuck on the bottom (pic attached I got from someone else on here) Just my view ......

Thanks Hornet Rider. Putting a 8mm reef anchor on my existing rope and chain should be suitable then. I currently use a 10mm silver rope with 4m of 8mm chain with 10mm shackles.

Brad ,yes I may trip the plough(sounds like a dance??), But it depends if it will fit through my bow roller. The last post was very informative,
Re tripping your sand anchor , I think there is a sand anchor with slotted shaft that fixes that problem, A fishermans anchor perhaps??

Come to think of it with your size boat I think all of this is probably overkill, and that a standard sand anchor setup as they come premade at boating shops would do just fine. Just picture how you will eventually feel driving away after you have cut it off , and spend accordingly.

Hi Brendan

I've been doing some research and the fisherman's anchor is basically a tripped danforth. Rather than using the cable ties, it has a sliding ring to pull the anchor up crown first. Problem with the fisherman's anchor (and the danforth) is that they don't dig in well on rubble due to there two large flat flukes.

On the other hand, a plough anchor will dig in quite well with it's single pointed fluke - just need to trip it in case it digs in too well and never wants to come back home.

Like you say, its all overkill for a 4m tinnie. Just get a $15 reef pick and I'm sorted for the type of anchoring I'll be doing. I've learnt a bit about anchors so it's all good.

Might see you at Mud one night. I'll be the one shivering in the tinnie.

Cheers

If you have a standard danforth (sand) anchor you may be surprised how much better they will dig into a harder bottom if you take the time to sharpen the leading edges with an angle grinder.

Most of them just have a rough folded edge and they can be easily improved.

Sure you do grind a bit of the galvanising away but it usually wears off on this bit anyway.
