what size anchor (weight) for a 9ft boat?

Hi

I have no idea how id work out what weight mud anchor id need for my little boat, im sure theres some weird and wonderful mathmatical equasion out there.

Anyone else use a little boat with anchor?!

thanks

Hi mic,

A small bucket full of concrete and a galvinised D ring set in the top, and attached to the boat with a bit of rope is the easiest, cheapest and very effective form of anchor. If it gets snagged, cut the rope and go and make another. On a 9 foot boat you shouldn't be navigating in to much of a strong flow, so I think this is the best idea. Hope the advice is useful.

hi thanks for that

i have thought about a bag of ready mix concrete, and then maybe over thought it.

a 2L bottle of coke weighs nearly 2kg. so if i fill an empty bottle and let set, obviously works out at around 6kg.

then i thought about physical size. at work we have some metal box section which would be heavier than a plastic bottle... so i could cut a short length, fill with concrete and hopefully should weigh a little more and be come compact. if i run a long bolt thru the middle i could attatch a few links of chain to it which would then stick out of the concrete to tie rope to.

still guessing at the weight of it tho

A small grapnel anchor is your friend, a couple of kilo should be fine.

When I had a small dinghy, I had a small grapnel with some rope wrapped around it which fitted into a plastic bottle, if memory serves correct.

It was a nice neat set up.

mic for fishing i always had 2 anchors so if you fet a upstream wind blowing you dont end up spinning round and round .concrete mud weights are fine start small and you can always add a length of galvanised chain via D ring to take pressure off the holding point if mud weight is not heavy enough ...small folding graphnel type anchors work really well again a small length of galv chain helps .
If you know a Carpenter then old sash cord weights are good as well Steve
