Brett's_daddy Posted September 8, 2015 Posted September 8, 2015 I have an Intex Mariner 3 rubber boat, it's a little over 9ft. long and probably 5 - 6ft. wide...it's a pretty solid little boat. I was wondering what size of an anchor would you use for this boat? The wife and I tried it out this past weekend and it performed well but one thing I did get tired of doing was always rowing back to where we wanted to be after the boat drifted (it was at night which made it even more of a pain in the butt). If I could get an anchor that would keep us in a specified vicinity that would be a good thing! Quote
Super User A-Jay Posted September 8, 2015 Super User Posted September 8, 2015 Get a little 10 lb musroon anchor and 50 ft or so of small anchor line. Should do you just fine. A-Jay 1 Quote
Super User J Francho Posted September 8, 2015 Super User Posted September 8, 2015 I use a 3 lb. grappling anchor with the tubes zip tied shut for a 14' kayak. You should be fine with that and 50' of parachute cord. Quote
Super User K_Mac Posted September 8, 2015 Super User Posted September 8, 2015 If you are not used to using an anchor, the mistake most of us make is not letting out enough line to keep an angle that holds properly. I don't remember for sure, but I think it is around 2 feet of rope for every foot of depth. Of course this will vary according to wind and/or current. I am sure A_Jay can give you the right answer, having spent a bit of time at sea. Good luck. Quote
Super User J Francho Posted September 8, 2015 Super User Posted September 8, 2015 How much you let out depends on whether you want to be stationary and how rough the seas are. Your double the depth isn't a terrible idea. Look up quick release rigging if it's going to be rough. It can save your butt. Quote
Super User A-Jay Posted September 8, 2015 Super User Posted September 8, 2015 Standard numbers for anchor line length is 5 - 7 times the depth of the water. With smaller vessels in calm conditions often times less will work; especially with an inflatable ride. A-Jay 1 Quote
blongfishing Posted September 9, 2015 Posted September 9, 2015 10-15 lb mushroom head anchor always worked for my 10 foot plastic jon boat. Always worked fine and should work for you. Quote
Super User Catt Posted September 9, 2015 Super User Posted September 9, 2015 Who came up with these numbers? I anchor my 16' Stratos with a 15# Tri-fluted river anchor in 15-18' of water with 25' of rope. If it's to windy for that setup I don't need to be on the water in that boat. Quote
Super User buzzed bait Posted September 9, 2015 Super User Posted September 9, 2015 i had the same boat as you for quite a while. i had some cheapo gym weights that i used for a while, bought them at goodwill for like $1 each i think. i kept a 3lb and a 10lb weight. on the rougher days, i took the 10lb and on calmer days the 3lb. agree with catt too that you won't need that much line for that small and light of a boat. just go to the bay or amazon and get you 100ft or 550 paracord for about $8 and you're set.

Brett's_daddy Posted September 9, 2015 Author Posted September 9, 2015 Yeah, definitely won't be doing any ocean fishing with this boat...strictly pond fishing. That being said, my favorite pond is about 30ft. deep in the middle. I spoke to my Dad last night and he said they used to take a 1 pound metal coffee can, fill it full of cement and put an eye hook in the top before the cement set. tie a line around that and use it for an anchor. 1 Quote
Super User Catt Posted September 9, 2015 Super User Posted September 9, 2015 How often do you plan on anchoring in 30' of water? Anchoring aint about the weight of the anchor, it's about the anchor digging into the bottom. I find the tri-fluted digs in quicker than the mushroom. Quote

Anchoring aint about the weight of the anchor, it's about the anchor digging into the bottom. I find the tri-fluted digs in quicker than the mushroom. That small inflatable craft will rarely generate enough pulling force on the anchor line to enable much "digging in" of any type anchor. Accordingly, the weight on the anchor will be what does most of the "Holding", As for design, a smooth round item is more inflatable ride friendly. A-Jay Quote
Super User Fishes in trees Posted September 12, 2015 Super User Posted September 12, 2015 That para cord will dig into your hands when you go to pull up the anchor, because it is so skinny. It is stout enough to do the jog, just kinda too thin for me. I anchor very seldom, but when I do I use 3/8 or 1/2 inch nylon rope because I find it easier to grip when I go to pull up the anchor. Where I fish, it is often much easier to tie to a tree than it is to anchor. My boat has a sturdy cleat on each corner of the boat and I keep a 15' dock line attached to the cleats all the time. Saves time & energy with the tie up line all ready to go. 1 Quote

A-Jay That is exactly why one does not need 5-7 times the length of rope than the depth of water and makes it a prime candidate for the tri- fluted river anchor. The tri-fluted river anchor has no points, is rounded, & vinyl coated. The three flutes dig in easily in soft to moderate bottom compositions. With a 20-30# tri-fluted anchor I've held 18-21' bass boats in 15 ft of water with only 25-30' of rope. Quote
Super User J Francho Posted September 12, 2015 Super User Posted September 12, 2015 It's a rubber raft, a soup can filled with concrete and a length of bailing twine would work, lol. 1 Quote

I also only use the minimum length needed on my small craft. The 5 -7 rule of thumb is in reference to larger vessels. Generally speaking if your boat is big enough to where you need an actual anchor chain in combination with the anchor line - you're usually going to need the extra anchor line length. If you're using kite twine - you'll be good. A-Jay Quote
Super User K_Mac Posted September 12, 2015 Super User Posted September 12, 2015 Catt I was the one who advised having enough anchor line to make sure the line is not too vertical. I have anchored many times in a light aluminum boat. A little extra length can make a big difference. Just enough to reach bottom is not enough. A_Jay answered my question about naval standards. Thanks A_Jay. 1 Quote

Super User K_Mac Posted September 12, 2015 Super User Posted September 12, 2015 A_Jay coincidentally that is exactly like the one I used to carry in my 14' tin boat! 1 Quote

Bonfire Posted May 23, 2021 Posted May 23, 2021 I have a 12 foot inflatable kayak what size mushroom anchor do I need for bringing it on intercostal,rivers,Springs? Quote
