    Old Brit Chance Maxi in Mazatlan

    Definitely not Equation or Masker, they were both lifting keel ketches. This looks more like a Dashew Deerfoot.

    Taxi dancer

    Cheetah was pretty fast, but suffered the same fate as the N/M 68's & first Pyewacket. They were all short boats with more sail area while the Santa Cruz boats were longer with smaller sails. They were pretty even until 1988 with the SC's a bit sticky in lighter air and the N/M types short on length in medium breeze and above. Then the IOR "improved" by correcting for the salinity when freeboards were measured. Everyone's calculated displacement went up so ratings went down. That allowed the SC boats to add sail to rate 70.0 again and improve their light air performance. The others could add sail or try and get even lighter, but it's hard to effectively increase their length. Taxi was designed after that and had sufficient length and sail area. Early on, she was plagued by being over optimized for Transpac with a very small keel and insufficient RM to go upwind. Her early rigs also had a tendency to fall down.
  3. The rule allows a full meter of head width between max and min. They must be seriously overpowered if they need to get smaller than minimum and resort to measurement tricks. I'm not sure the AC sail measurers would measure the straight to the batten tips. It would be to the intersection of the projected leech segments.
  4. The Italian boys are FOS. This is more likely a quick and dirty test of a smaller head width for heavy air. It's cheap and easy to modify an older existing main this way and not sacrifice a set of battens, nor mess up all the shape control scheme in the top of the sail. At around $200 per meter, the 16 battens (8 per skin) will run near $20k. If the concept is good, then you build a sail to size with a proper set of battens.

    Luna Rossa Challenge. AC 36

    The flange is spanner to rotate the mast. As such, it must be parallel to the deck surface while the mast is raked in relation to the deck. Unlikely it is hinged, but quite probably that they are not perpendicular to each other fore and aft.

    Hydra Net vs 3Di

    Hydranet is essentially a woven polyester with a small amount of Dyneema added. This creates a dilemma in finishing the fabric because the Dyneema melts at a temperature below that at which normal woven dacron experiences in the finishing process. Shrink is a big part of the dacron finish process and serves to tighten the weave before any resin is applied. Hydranet is loosely woven and without shrink, all that is left is to spread on a thick layer of resin to stabilize the material which can be seen in this photo: The resin adds significant weight and makes the material stiff until it breaks down, and when it breaks down, the sail shape will change for the worse. 3Di will make a stronger and lighter sail than Hydranet for similar money depending on which 3Di product you look at. 3Di can be all poly or blends of poly / aramid, poly / dyneema, aramid / dyneema or aramid, dyneema and carbon. You won't find any Hydranet in the IMOCA fleet but you will find a lot of 3Di.

    Results as they come in

    You disagree that most Americans want an end to the partisanship? All the more reason that None of the Above should always be a candidate in the primaries.

    Results as they come in

    The whole election proves that the extreme left and right are not popular and most voters want a moderate approach that allows for compromise to get things done. What voters want is to forward movement on the serious issues that are crippling the country and end the political gamesmanship.

    Old sail or new sail?

    Square Top Foresail. Ditch the heavy gaff with all its strings and issues. Keep more of the esthetics with less of the tradition.

    Please stop calling it a skeg. It is a keel: Skeg - Wikipedia en.wikipedia.org › wiki › Skeg A skeg, (skegg or skag) is a sternward extension of the keel of boats and ships which have a rudder mounted on the centre line. The term also applies to the lowest point on an outboard motor or the outdrive of an inboard/outboard. keel1 /kēl/ noun noun: keel; plural noun: keels the longitudinal structure along the centerline at the bottom of a vessel's hull, on which the rest of the hull is built, in some vessels extended downward as a blade or ridge to increase stability.

    Soundbar Anarchy

    I started with a Sonos Beam which has since been supplemented with a Sonos Sub and a pair of Play One's for the family room TV to give surround sound. I liked it enough to add the Sonos Amp which now drives the other wired speakers I have around the house and allows my turntable and CD player. Since they are all connected and can stream from my media server, Pandora or internet radio, I now have a system I can control from any room on my phone, separately or together.

    Headfoil vs Hanks, thoughts?

    Not that any non GP program could measure. Aerodynamically hanks are draggy vortex generators, but the fact is the cumulative loss on the course is far less than any of the handling mistakes a crew of weekend sailors will make in a race.
  13. Back in the mid 1970's I left Chicago on a 60' sloop with the rig on sawhorses in October. Down the Chicago River to the Illinois to the Mississippi and all the way to New Orleans before stepping the rig again. The following spring we returned via the Hudson River / Erie Canal. The Mississippi was interesting but long and hard. we could not motor back upriver against the current. A year later, I took another boat out via the Erie in late October and it was quite beautiful with Indian Summer. I strongly recommend it. Wardell's Boatyard in Tonawanda was where we stepped and un-stepped the spars at the west end of the Erie. He had a tow truck he backed up to the guardrail of the bridge next to the yard. He would lower the hook over the side and then hang cinderblocks on the bottom of the rig to get the balance right since he couldn't lift high enough. Scary as hell as the boat captain, but we never had an issue.

    Falsification of Race Data

    What difference do times make when PHRF ratings are mostly made up anyway?

    Older well known IOR Boats

    Running Tide and Dora IV (Tenacious / War Baby) were similar S&S 61 footers with a good rivalry. The first race of the 1974 SORC started with a beat out of Tampa Bay and the two boats were neck and neck as we approached the bridge and the breeze freshened, making it time for a sail change. On Dora, our #2 genoa was a 2 ply 6oz Dacron sail weighing near 200 lbs. and hanked to the forestay. The standard sail change involved hauling up the new sail (bricked) from the forepeak and hanking it on to the forestay. Then we set a forestaysail on an inner stay and sheeted it home before dropping the old headsail. I sat on the bow facing aft and undid the old hanks as fast as possible while 4 guys wrestled the old sail down and to weather. When the old head got to me, I swapped the halyard to the new one and up she went. The new sail was sheeted home and we dropped the staysail and flaked and bricked the old sail as best we could (no sausage bags yet). While easy to write, this was a ball buster of a change and pretty much all hands (18) were scrambling to get it done. Tide started their change just about the same time as we did. Timmy Twinstay had just come out with his fore and aft grooved aluminum stay and Tide had one. No staysail for them, and no hanks. I can't say if they hoisted inside or outside, but the tack change hadn't been invented yet and when I finally had a chance to look around after our change, there they were a quarter mile back with a crowd of guys on the foredeck still struggling to get the old sail down. By the time they were cleaned up, we were probably a half mile ahead. Sometimes new isn't better.
