    scored a 50$ hobie cat

    Congrats, that is an awesome score! I don't personally fancy smaller beach cats much, but I would buy one for that price! We had a rather long (200nm) cruising trip with our Formula 18 catamaran with my wife. Everything except tent and sleeping bags went through inspection hatches to hulls. There was plenty of space but small inspection hulls limited access quite a bit. In total for two person and one week (excluding some of the water, as we knew we could refill that) equipment, food, clothes, camping gear was something like 15kg in total. I highly recommend waterproof bags for everything. Even if your hulls do not leak any water (we have a very small mystery leak somewhere), those are really nice for organizing stuff. We used drysuits, as wetsuit gets really uncomfortable after a while if there is no time to dry it and shower. For navigation (we have thousands upon thousands small rocks all around) we had a small handheld GPS and laminated paper maps. Paper maps were for route planning, and GPS for actual sailing ("can we still go closer to those islands or do we have to tack already?"). It was an awesome experience, except for wind direction - we typically have south-west winds but for that week it was almost exclusively eastern winds.

    As said more than once already, we do not have 3rd reef/trysail. And we do not have #4 jib. We do have storm jib, which is way too underpowered for beating in big waves, it's usable for going in general direction you want to go, but not for VMG. We had okay-ish VMG for upwind, even though we heeled way too much (better VMG than when trimming for flatter boat with sails we had available). We would have used smaller sails for upwind if we would have any good choices for that. We did not have washboard, because we knew from experience that in even in a bad wipeout water is not coming even close to the hatch (and as said before, that is not a reason to not to use washboards just to be overly careful).

    Good points. About this one, with 2nd reef on the main jib is not backwinding the main. There's no good slot between jib&main, as the main is so small. In general, this is what we do with full main (but change in jib sheet is something like 2-5cm, not 25cm).

    It is funny how comments in this thread can be categorized roughly to following buckets: "Idiots, stay home instead"; stupid comments on how everything is shit Constructive commenting about what went wrong, what could be done etc. "Cool"/"Wow"/... Cool videos/photos from others A single wide-angle video - especially one including cuts - is missing a lot of information, as you can't know what happened before the cut, outside of the picture, and have only very rough idea of the conditions. What I learned from reading this thread is that people make awful lot of assumptions. For example, Upwind trim: as crazy as it sounds, we trimmed for good VMG for the sails we had available for the conditions we had. We went way faster and higher while being heeled way too much. What went wrong was way too tight main sheet in tacks shown on the video. Canvas size: yes, we knew very well we had way too big sails upwind. However, that is the smallest jib we have (in addition to a very small storm jib, which would not provide enough power to move us forward in that wind and in those waves). We don't have more than two reefs on the main. But we decided to go to learn anyway, instead of "oh well, we don't have optimal sails for this weather, let's stay at home". Video does not show what happened before kite takedown (except that we managed to mess up the lazy sheet, but reasons for that are not visible on the video). Assuming that is how we planned to take it down is... stupid. Everything went according to the plan until tackline was accidentally opened (first a bit and then fully). Until that point everything was fine, and kite was coming down nicely. Downwind trim & kicker: it is not visible from the video, but true wind was basically straight behind us. Kicker is just tight enough to keep the sail from twisting around lower spreader. Letting it out more would not help, and we did not need more power downwind. From the experience we knew even on a really bad wipeout waterline is not coming even close to the hatch, so we did not have washboard in place. Thinking about it now, there is no particularly good reason not to put it there just to be overly careful. There was ~2 hours of video, and what was shared were the best and the worst moments. It could have been cut it to only include good hoist, nice downwind clips (for 15 minutes or so), and a few good tacks, some upwind before going to heaviest winds, and no-one would know what happened. However, what we have understood over the years is that pushing the limits, failing miserably together with experienced people, and then learning and sharing those failures is the best way to learn.

    I have no idea where you took that 3.8m. In any case, I took that readings mentioned on the video and in description from nearby local meteorological institute's observation data. I also have no idea how you are going to measure waves from wide-angle videos without any good reference points, especially for longer waves.

    Indeed we did learn a bit about keeping slack sheets tied up. The problem started when while broaching slack line needs to be opened, and then it was no-one's responsibility to secure it again. For jib (during takedown), it was a conscious decision to let it be and save the kite, and clean up the mess afterwards. Kite takedown failed when tack line got opened by accident. Until that point everything went according to the plan, and after that it was not pretty.

    I should too, as we're getting this kind of winds perhaps five times per year, and some of those are during winter.

    We get this kind of winds very occasionally (this was the second time for this boat in a few years, I believe), so it is not worth buying&carrying storm/trysail, or adding a 3rd reef. In case of emergency, we could still manage to make it to safe harbour without that (with overpowered 2nd reef / with storm jib / with jib only / with engine).

    Another downwind clip from day before with multicamera footage, smaller crew and a bit lighter winds (around 25kts instead of 30-40).

    We didn't use tethers. We discussed using those before and after the sailing. See for example this post. I would prefer being on the water waiting to be picked up over being dragged next to the boat going 15kts (and closer to 10kts even when broaching a bit). It is really difficult to tether in a way you definitely stay inside the boat, except for cockpit. Guy (gal in fact) who was on the water twice had drysuit on, as did two others as well. We went upwind first (for the most part, there was some beating after downwind leg) Smallest sails we had (except probably could have used storm jib instead of smallest #3, but then again beating with storm jib in big waves is not working very well).

    J/92 heavy weather sailing

    Well, shorthanded does not mean single-handed. We were shorthanded, as we usually sail with six onboard, and there's stuff to do for six.
  12. We went for some heavier winds (30+ knots) and big waves (3+ meters (13+ feet)) with J/92: https://youtu.be/YA_3WMmYGzA. Surfing 18+ knots down the waves with 2nd reef and our smallest spinnaker was awesome. Near the end we went 14 knots with only the mainsail up. The boat was planing all the time, except when close-hauled - anything even close to beam reach and the wave separated. We didn't hike, as due to the wind we went basically straight downwind. In the end we managed to mess things up a bit, but recovered without breaking anyone or anything (except one small barber hauler block). Also multi-camera video from short-handed surfing with a bit lighter winds: https://youtu.be/lt2RsHb4uzo

    M32 racing

    M32 Scandinavian series is visiting Helsinki, Finland this weekend. Some drone footage: short, somewhat coherent video and collection of random clips from the same event.
  14. I shot a short video of two Formula 18 racing catamarans sailing in Helsinki, Finland. Any comments? It is surprisingly hard to have stable video from above, when there's no fixed things visible, only moving boat.
  15. I shot a short video of two Lasers (and one other dinghy) training in Lauttasaari, Helsinki, Finland: https://youtu.be/bIQeAKvRm0I. Temperature was around 4°C, and water is close to 0°C, as there is still some ice left. Related to this, one rudder was dropped and dived from freezing water: https://www.facebook.com/hskakatemia/videos/1440877269308997/ (not my video / post, but from the same training session).
