A: How to repair a surfboard leash?

A: How to get out of thicker wetsuits efficiently and quickly? In the Falklands, because the water is so cold as it comes up off the Antarctic peninsula, I always wore 6mm wetsuits even for kayaking. The two solutions we used were: talc. Yes, it gets wet, but really helps with seals round wrists and ankles a friend and solidly rooted poles or bars. Much easier... (more) |

A: Can I make a safe climbing-anchor with a 2-ton working-load sling that was meant for lifting vehicles? My only concerns would be around its tear resistance (in case of rubbing against a sharp bit of the tree) and bend radius. If those are appropriate, then it should work as a sling. Be aware that it will have no elasticity, so you'll still want to build in whatever "give" you need, but a short sling... (more) |

A: How much heel is optimal on a small katamaran in low wind? As you mentioned, a vertical sail gives you more power, so where possible that should be your goal, but the drag caused when heeling is enough that for most catamarans you want to minimise it as much as possible. So aim to keep the windward hull just out of the water in calm seas, and a little high... (more) |

A: What to do with a yacht when a stronger blast come? If your concern is regarding broaching, then the two actions you take are: allow the head to come towards the wind, reducing the sideways force. This can be instant. if needed, slacken the main, depowering the sail. Unlike in a dinghy, where this can also be an instant move, in a yacht this is a bi... (more) |

A: What are the differences between boats and "ice yachts"? Early ice-yachting was done with converted boats, but that is rare now. There is a class designed for unstable ice that can sail in water if needed, and in the Netherlands blades are still added to small boats in the event of a cold enough winter to allow ice racing. From @Willeke: Link in Dutch, ... (more) |

A: Skiing demo plate vs no demo plate If you know exactly where your bindings need to be fixed then you don't need the demo plate, and fixing directly to the ski gives a more rigid connection between boot and ski. A demo plate is only really useful if you need adjustment. (more) |

A: What's the hardest wearing multibraid rope type? Dyneema is the most hard wearing, however if you need it to run through any friction grip or clutch it is not a good choice as it is very smooth and shiny. Polyester really is the cost-effective, UV resistant and strong, especially when paired with a Dyneema core, so this is probably the way to go, ... (more) |

A: What is the purpose of being close-hauled when sailing upwind? While a close-reach or beam-reach is going to give the vessel the highest speed through the water, this may not be what you want. Being close-hauled will point you higher so while you lose speed, the end result may still be faster to your destination, or more appropriate through narrows, or in order ... (more) |

A: Are coasteering routes graded, or does one have to rely on a qualitative description of the difficulties of a route? From the coasteering excursions I and my family have been on in Scotland, the rest of the UK and some other European countries, there appears to be no consistent grading. What I have seen is use of common grading for the climbing parts plus usually a comment on the "relative danger" on the drop to w... (more) |

A: Why is there a cock vane/feather? This one is actually much simpler than you might realise: On a three feathered arrow, the nock is at 90 degrees to one feather, and at 30 degrees to the other two feathers. If the cock feather was pointed towards the bow, it would be much more likely to hit the bow than the other feathers would if ... (more) |

A: When, how and by whom was sport climbing invented? According to what I can find on Wikipedia and elsewhere, it looks like it was in the 1880s. Before that, bolts had been used as climbing aids. Best candidate for first climber and route is W.P. Haskett Smith up the Napes Needle in the Lake District in 1886, however most climbers that used artificial... (more) |

A: How can I be sure that I'm ready to do the Three Peaks Challenge? I have a few colleagues who have done this, and one team who did it with a colleague in a wheelchair. They are all reasonably fit, but the day job is desk-based, so if you have managed Kili easily, and train regularly, I can't imagine you will have many problems. I'd suggest you go for it. You will ... (more) |

A: How can I tell how much, if any, rain is in an approaching cloud? Randall Munroe has the single best article on this I have ever seen, over on his What-If site where he discusses what would happen if all the water in a cloud formed one giant raindrop. I recommend reading the whole thing, even if just for the destructive vision he has, and especially the final line... (more) |

A: Why don't climbers use electrically heated suits? Firstly there's the weight issue - as Paparazzi commented, batteries are heavy! Then there's temperature - battery performance drops considerably in the cold And finally reliability - if your electrical circuit goes, you will freeze unless you have properly insulated clothing... so why bother havi...

A: What is the ecological justification (if any) for bird feeders? If we exclude the birdwatching explanation Shem gives, the only possible ecological reason for a bird feeder is to counteract the negative effect we have on the bird's habitat by having our house there. This doesn't explain why we only tend to feed "cute" animals - if we are to be honest about ecolo... (more) |

A: Do squirrels have front and full peripheral vision? Like many prey animals, vision is optimised to detect danger coming from anywhere. They can see you with one eye very easily, and their reflexes are on a hair-trigger to take them away from incoming attack. They can see above them, and all around, with a blind spot to the rear, and a very small one j... (more) |

A: What could be the cause of condensation on the tent floor? Condensation is usually caused by high humidity combined with a temperature differential. It sounds like you have a very humid atmosphere, which in a tent is added to by the high moisture content of your breath, and if you are warm at night, also sweat. It doesn't need to be that cold, especially no... (more) |

A: How often should I change the lines and sail attachment rings? I have always taught sailing students to run a full check every time they rig the boat (if it's a dinghy or the mast is regularly lowered) or annually before returning it to the water after winter. Additionally, a full check after any collision or incident, or after heavy weather/storms is recommend... (more) |

A: What should I look for in a used wet suit? Always check used wetsuits for wear, especially around seams, under arms, between the legs, and the seat. These areas typically wear through fastest, and although they are often strongest (extra stitching and padding) they take a lot of punishment. Check internal stitching carefully, as well as any ...

A: What are the measurable prerequisites of strength and/or flexiblity for starting to climb in a climbing gym? One aspect not yet touched on is that for beginner climbers, upper body strength is not actually as important as you might imagine. If we exclude overhangs (which is reasonable for early stages of training) then legs really are where all the power requirement sits. In fact when teaching folks on cli... (more) |

A: Do flashlights (torches) with multi-color capabilities have any applications for usage in the great outdoors at night? Red has been covered already, and it really is the most practical colour to have with you at night, as it is the only one that doesn't impact your night vision significantly. The others, though, are useful for all sorts of signaling or navigation purposes. It can be easier to signal a red or green r... (more) |

A: How can I build a board to mount climbing holds in my house? Typically, using 3/4" (19mm) plywood board is strong enough for this use. And the bolts you want are 3/4" (19mm) plus enough each end to screw into the hold and to accept a nut. Bolts used for most holds are M10 or M9.5, so check which your hold supplier uses, and then make sure the holes you drill ... (more) |

A: Why do most tents have black floors? One reason (and I don't know enough to suggest this is the main reason) is for identification. When putting a tent up you may have a bundle of fabric that you need to set down on an uneven surface, sort and erect. Having it in black distinguishes it from the varied colours of the tent walls so you c... (more) |

A: Why would fatigue cause fever? Fatigue itself shouldn't cause fever, as it is really a symptom, not a cause, however being fatigued definitely leaves you less able to defend against illness, and an oncoming fever or illness makes you much more likely to be fatigued.

A: Is the fishermen's greeting "Petri Heil" accepted all around the world? I grew up in a fishing community on islands north of Scotland, and never once heard this.

A: Do jellyfish actively avoid swimmers in Mediterranean? Jellyfish, while mobile, are not capable of much evasion.

One thin... (more) |
