    505 vs. 470

    A long time ago, in a galaxy far, far away I owned a 505 and sailed a lot on 14s, 470s, fireballs, and other planing dinghies. The 505 has a LOT more room in the cockpit and is much more comfortable to relax in (between firehosing).

    VOR Leg 11 Gothenburg to The Hague

    So does anyone else foresee a jibe-fest down the ice-exclusion-zone windfarm-exclusion-zone ?

    VOR Leg 10 Cardiff to Gothenburg

    Have to admit, the Norwegians certainly like their lighthouses. Maybe it's because sailing in a North Sea Gale makes that a lee shore. Anybody know the sea state now along that coast? It's only about 40 nm distant from the fleet.

    Old 5o5 rigging in Tacoma

    Hi Locus, I don't know. Dust will shortly be smelling those strange petrochemical odors.

    Old 5o5 rigging in Tacoma

    Holy time warp, Batman ! ... This is a 505 time capsule ! This is a Parker K series boat, notoriously slippery, rigged exactly like the winning boat of the Bermuda worlds in 1975 by John Loveday/Lewis Dann. Easy to spot from the rudder and the famous 'Loveday Loop' mainsheet horse. It was a period of total innovation in 505s; eliminazione of the traveler, lever vang controlling mainsail leech tension, shrouds controlling forestay tension. This eventually lead to the modern ultra-rigid (read costly) hulls. Dust, you have a winner in the Concours d'Elegance if you can just put it back together with the pieces you have !

    Old 5o5 rigging in Tacoma

    Hi Dust, The american section of the international 505 class is strong and friendly (a motorcycle gang on the water). Get started here for contacts and rigging tips: http://www.usa505.org/ Trailer the boat with all the parts to the first regatta you can find. You'll get plenty of advice. Rig it. Sail it. Changing layout is part of the fun. Be careful, 505 sailors don't move up to another class, they just go to the worlds more often.

    Camino de Santiago

    Hi Point Break, I walked the Camino de Santiago in April of 2016 at the tender age of 64. I started at St Jean Pied de Port continuing to Roncesvalles, Pamplona, Burgos, Leòn, Ponferrada, Samos, Melide, Santiago de Campostela, Finisterre, Muxìa. It took me 40 days to cover slightly more than 900 km. I can only offer a couple of suggestions. Travel Light : I only took one pair of pants, one t-shirt, one long-sleeve dry shirt, a hoodie, a windbreaker jacket, a watch-cap, two pairs of underwear, three pairs of socks, one pair of trainer shoes, one pair of leather sandals, a pair of flip-flops. and a towel. In a 40 lt backpack, with rain-cover, I also brought a light synthetic summer sleeping bag, a water bottle, and an increasing amount of medicines. I bought, along the way, safety-pins to dry out the socks on the stern of the backpack, a wide brim hat, and a couple of t-shirts. Take Care Of Your Feet : After 20 km of walking, mostly on hard-packed dirt or asphalt roads, my feet hurt. After 25 km, my feet screamed to stop. After 30 km, I knew I was causing damage to them. I noticed that many of the persons wearing hiking boots were having problems with blisters. I was super careful to apply baby-cream and after 8 days I thought I was going to get through it without problems. Then wham, the ankle and knee tendons got inflamed. I remember after a lunch break, I got up and could barely walk heel-to-toe. Fortunately the pharmacies in Spain are allowed to sell effective anti-inflammatories (ibuprofeno) over the counter. The pharmacist was also very understanding and took the time to explain it while we worked on the translation. Weather Window : Basically, you have to choose between mud and hot. I started on March 31 only to discover that the pass Napoleon used to invade Spain was legally closed due to snow until April 1 and possibly beyond that. The fine of 1000 euros for trespassing was more convincing than the receding snow; we walked the road. We got rained on and down-poured on, but it was never freezing cold. When the sun was out it was hot but not Dalì-melting-watch-hot. Mostly we walked through green farmland, lots of mud. We never had serious problems finding the cheaper 'municipal' hostels because the offer was more than the number of pilgrims and we walked relatively fast. I came to understand that in the summer, people would leave the hostel well before sunrise, in part to escape the heat, but also to be sure to get a place at the next first-come-first-served hostel. The last 100 km was more like a religious procession as this is the minimum distance for the 'credencial'.

    R2AK 2018

    Hi RickW, I have no dog in this fight, so I'll just make one clarification and let it go. In the podcast at 25:44, Adrian cites a study by Harvard University which states "the efficiency that you can achieve with that kind of [flapping] propulsion is higher than that you can get out of a propeller, and the gain has been experimentally shown to be about 20 to 30%." I don't know the bibliography of the Harvard publication. I'll let you know how the record attempt goes.

    R2AK 2018

    It's not for the R2AK this year, but a professor of zoology at Oxford, Adrian Thomas, is working on a whale tail as a propulsion mechanism that has a 20–30% efficiency gain over a propeller and works over a higher range of speeds. With the craft shown below, Malolo, he hopes to break the human-powered 20 knot barrier this summer. The podcast from the BBC is pretty good with the specific human-powered water propulsion stating at 25:30. Sell your quadcopter. https://player.fm/series/the-life-scientific-1301276/adrian-thomas-on-the-mechanics-of-flight

    Macif / Gabart / Jules Verne 2017-18

    Thank you Laurent !!! Your contributions and translations (for years) have made this a great thread. ... I cannot help but wondering how much the autopilot technology has matured in this last decade? Imagine trusting your autopilot at 35 knots for a couple of hours of sleep in a picklefork at warpspeed (thanks JS).

    Hard vs soft dinghy

    I remember reading a few years ago that Farr Yacht Design was involved in a racing SUP. http://www.farrdesign.com/749.html

    My newest project

    Hi Bob, The Row-Away-Factor here is awesome. Congratulations to you and the team. I do have one comment and one question. I should warn you in advance that I hate single-line-reefing. Regarding the photo below, I could be wrong but it seems that: -the reef line is fixed at the boom where the maximum leech tension is -passes through the clew ring with a 180° turn -passes through several rings-on-shockcord (which should automatically flake the sail as it is lowered ) -passes through the outhaul sheave box at the end of the boom where the maximum foot tension is with a <180° turn -passes through the front-of-the-boom sheave box with a 90° turn -passes through a guide on the mast -passes through the tack ring with a 180° turn -passes through a guide on the mast -passes through a block near the deck with a 90° turn -passes through a deck block on the cabintop with a 45° turn -passes through a stopper at the cockpit [/rant] On some of the bigger boats with a 'V' boom, there is a genoa track attached inside with pull-pin cars for the reefs (because once you find the position, there is no need to adjust). If the winches are big enough (and in this case they are) there is no need for the 2:1 purchase. Next time out, could you take a photo of the reef setup at the aft end of the boom? Thanks, Mark

    Thoughts on Boom Tents

    Nice. Should have a (split) back flap too; for when the sunlight comes from the stern (case in photo). The ones I have made, similar to this, have the 'pole' as wide as the deck. I have always wanted to try and use the spinnaker pole on the boom topping lift / main halyard for that extra wide shade. Alas, no takers.

    Top tips when sailing across an ocean

    Chafe is like rust ... it never sleeps.
  24. Hi Dave and Steve, First of all, my compliments for combining the major breakthroughs in sailboat design and construction for the last 150 years in a unique and new vision. From you two, we don't expect less. I couldn't help but notice that the dimensions of the UFO are roughly that of an inflatable dinghy. The volume is less (catamaran) and the weight is much less. So I have a few questions regarding the possibility of using the boat as a tender. 1) Is it unsinkable? 2) Does it tow well (and where do you attach the tow lines)? 3) Can you stand up and paddle (SUP)? 4) Can you row it? 5) Will it make it to shore in calm water with 2 FABs? 6) the $64 question ... an outboard? X) I don't care what it rates. P.S. I couldn't easily find the dimensions; LOA? Beam? mark
