Answer	—	A: Surfacing out of a sunken ship/submarine - Survival Tips The other answers compare the situation to those where a SCUBA diver has to ascend immediately due to gear malfunction. Since you specifically ask about escaping from a sunken ship/submarine, I wanted to point to references explicitly stating that the same techniques are (or were) used for submarine ...

Answer	—	A: How did/does shrinking canvas effect sailing ships? There are no similar issues with sailing ships. Sails are never designed to fit tightly within any kind of frame. To be effective they must be able to change shape and position, something that is done with lines (called sheets). Most sails are fastened to solid objects only on one or two sides (occa...

Answer	—	A: Is there a point at which one is committed to a tack? Yes there is, but the situation being described is probably not exactly that. If we consider a standard sailboat with a headsail and mainsail, as the boat turns into the wind the wind pressure on the headsail tries to push the front of the boat away from the wind. As the prow turns across the wind, ... (more)	—	over 6 years ago
Answer	—	A: Do square-riggers also use 'aircraft-wing-style' propulsion? TLDR: Yes, square riggers can use the airfoil type propulsion, though not as effectively as a fore-and-aft rigged ship. In slightly more detail, there are two reasons why this is the case. Despite the name, a square-rigger can in fact turn its spars. Spars are the things the sail hangs from, and t...

Answer	—	A: Understanding a ski resort weather report To add to Can't Tell's great interpretation, a good day to go snowboarding would mean: Not so cold it's uncomfortable to be outside (adequately dressed) Not a bad day to be outside for any other reason Not so warm the snow is slushy, or worse melting. Snow not melting for any other reason Snow deep... (more)	—	almost 7 years ago
Answer	—	A: What do surf report terms like "fading WNW swell" mean? Wind directions are always given as the direction the wind is coming from. It would be natural for surf reports to do the same. This is born out by looking at Surfline surf reports for the West coast of North America. Surf is invariably reported as have a direction of somewhere in the western half ...

Answer	—	A: Modern equivalent of a flare gun? While Charlie Brumbaugh's answer is good, there is a cheaper and simpler alternative: a LED marine distress flare. These are handheld LED lights, as bright as a distress flare. Many jurisdictions certify them as legal substitutes for distress flares. However these are substitutes for handheld flare...

Question	—	Avoiding microbial contamination of diesel fuel I have a diesel powered sailboat. What are effective ways to avoid microbial contamination of the diesel fuel? And what do you do if the fuel becomes contaminated? [This question originally asked by Curd on the Sailing Yachting and Seamanship proposal] (more)	—	about 8 years ago
Answer	—	A: Where to sleep while bike-touring southern Ontario? [x-post from bicycling] I don't disagree with Kate, but let me add some alternatives. First, let me make sure you are aware of the Waterfront Trail, which should cover a lot of your route. I would absolutely recommend the detour into Prince Edward County, which is excellent biking territory as well as being worth a visit o... (more)	—	over 8 years ago
Answer	—	A: Sailing with an infant I have friends with a sailboat who wanted to take their <1yr infant on their sailboat with them, and so consulted the (Canadian) coastguard about how best to protect her. The good news is that very young children (< 2 yrs, I think) don't count as passengers from a legal point of view; so there... (more)	—	over 11 years ago
Answer	—	A: How should I check that the anchor is secure when I anchor a small yacht off unfamiliar land? What xpda writes about setting the anchor is right (although hopefully you know this if you are sailing your own boat). As well as what he says, make sure you have the right kind of anchor for the bed, and you have enough rode (rope or chain). For overnight it should be at least 7 times the water dep...

Answer	—	A: How would you evaluate sailing lessons for adults? I was lucky enough to take both dinghy sailing lessons and later cruiser sailing lessons. It's an approach I'd really recommend. Sailing a dinghy will teach you to watch the sails and the wind much more easily than in a cruiser. All the skills you learn in a dinghy will apply to a cruiser (except cap...
