It's not so much the breaking strain of the rope but the 'holdability' if that's a word. You would be perfectly OK with 8mm nylon but it is thin and therefore hard to hold when pulling up an anchor. Idealy 12mm Nylon is just about as thin as one would want to go but at a pinch on an inflateable you could get away with 10mm. Nylon sinks so does polyester, polyprop floats and does not feel good in the hand. Over all Nylon is best. The economy end of the Nylon rope is 3 strand twist 12mm. Expect to pay 50p to 80p a meter in small quantities. How long? Well you need to look at a chart or find someone to tell you how deep the deepest area is where you normaly fish, and then X it by 4. If you want a bench mark you need to be looking for at least 50 meters of rope certainly not less.I need an advice, please!
Ive bought a Quicksilver inflatable Heavy Duty 4.30 meters boat with 30hp Mariner two stroke outboard engine. I have 4kg anchor with 2meters chain.
What rope do I need for the anchor?
VladThanks for the great and detailed advice Afishionado!
Where can I find sea charts on the net? Do you know any sites?
8mm? Bit hard on the hands too thin I feel. 10 or 12mm makes a big difference. 220mtre polypro coils on ebay for 17.99 plus post. I need that for were I fish but I think you can get shorter lengths pro rata on price.You could use 8 mm polyester rope (for boats up to max 1000kg), you should use it with a 6mm chain. Are you planning to go fishing at anchor, or is it for emergencies only. If you want to fo fishing at anchor I'd suggest a bit longer chain (eg 4 meters). It makes the boat behave better in waves and protects the nylon from the rocks.
You could use lead-core, but I don't like it. It's often used bij sailers on smaller boast, who only use the (umbrella) anchor when having a swim. Chain and polyester is a lot cheaper and even better then lead-core.
And buy enough anchor rope, don't settle for 30 m. You'd need at least 2 times the depth your anchoring at. And if you've got enough space on your boat dubbel that lenght. There is no better spare anchorrope than the one connected to your anchor.

You didn't hope for a simple answer did you?Hello Monktonlad
I have been loking for a site like that for ages.
Tell me, about the depths:
a) are they in metres, feet, fathoms (not that obvious to me, unfortunately)?
b) do they signify depths at bottom tide or top, and then is it neap or spring?
Thanks in advance.

The chart will be drawn to WGS 84 datum, the default datum for GPS, this means that as long as you havn't changed the datum on your GPS set any positions you take off the chart will be able to be entered into your GPS without converting them.Hello Monktonlad

It wasn't a simple answer and you beat me to it while I was figuring a way to describe itYou didn't hope for a simple answer did you?0)
Depths in Meters (3.3ft)
Depths are measured on the basis of the water being at the average of the low water depth throughout the year ( That's the simplest answer don't worry about the details)
Don't bother your self adding the current water depth over the indicated depth as in general terms for fishing it doesn't matter. UNLESS you have a huge tidal movement like the Bristol Channel for example.
If you want to do the maths you need a tide table for your chosen area. This will give you at any point in the day a figure that represents the hight of the water in addition to what the chart says.

The legend shows the depths in meters but I have just checked my local area and they are depths in feet, I have checked this on Garmin's G chart software, RYA local chart and the Amiralty chart of my local area.
Just sent an email to C map to confirm, bit dangerous if they do have it wrong as I suspect.
Take care, this theoretical minimum depth can be less than that stated!!! Depending on weather, (wind driven swells mainly) water minimum depth can vary by 0.5 meter in my area!!! And thats not weather in the local area, it can be weather hundreds of miles away. Local knowledge!! Every thing on charts must be treated as 'approximate' or 'average'?They are always the depth of the water at the lowest astronomical tide (a theoretical minimum the water can ever go) In practise there will never be less water depth than shown on the chart.
