  1. From the tactic page press the down arrow to go to the start line page. I never use it but as far as I remember that is how to access it. Do you have a regatta or HR processor? These allow you to enter a polar. But it's much easier to not use that polar and have Expedition drive all your performance data.
  2. I assume those are your full crew targets Peter? I have an ORC speed guide for my boat with a crew weight of 135 kg. I scale the 10m winds in Expedition by 7% to obtain mast height numbers. As I sail on non-tidal water most of the time my log is now very well calibrated as well and the ORC polar proves to be very accurate. Still, downwind in light air I can exceed the polar by 1-3%. The target heel is about 25-30 degrees (upwind) for >10kt of wind.
  3. My tip: Get an ORC Speed guide for your short handed configuration (especially: reduced crew weight). I found the ORC polar numbers to be very accurate and they can be good "target" to shoot for and make you understand if you are sailing the boat well or not. The speed guide also contains target heel. You will be surprised how much heel the J/111 likes to get the best out of her!
  4. Afaik the boats always come standard with an aluminum boom. I have hull 107 which has an aluminium boom.
  5. Sure, halyard should be marked for all reefs. The loop I have attached to the webbing is maybe only 10cm in size. I use it only the keep the sail down with one hand, while attaching the shackle with the other. Without the loop the flapping sail can be hard to keep in place while trying to get the shackle in the webbing. Another "trick" I did to make reefing more easy: At the leash of the sail I use a traditional lasso rope around the boom. Sometime this lasso moves forward on the boom when the reef is nog in use. When you then put in a reef, the reefing line does not pu
  6. Like Blur, I use a shackle at the mast to fit into the reef webbing on the sail. As it can be quit hard to pull down the sail when staying at the mast, I fitted a short loop of rope in the webbing of the sail. That way it's easier to grab the rope loop and pull the sail down towards the point that you are able to hook the shackle into the webbing. Sailing shorthanded I reef from approximately 17 kt TWS (upwind, depending on sea state)
  7. Congratulations! I sail my J/111 two-handed or solo all the time and it's a great boat. We use it for races, day trips, weekend sailing as well as longer cruising holidays.
  8. I can echo that; Connectify works great!
  9. Did you make any reinforcements below deck to fit the pad eye?
  10. I have a J/111 on which I do a lot of solo and two-handed. Main mods I did to the boat to facilitate this: - Cunningham let back to the cockpit - Vang adjustable on both port and starboard side of the companionway - Jibs with soft hanks - code-0 on furler - proper autopilot with remote - Trimming marks on all lines. Especially important to mark the halyards for each reefing point and full hoist points. Same for tackline. - Performance data and course data from Expedition made visible on displays in the cockpit - Forward/outboard lead positions for the j
  11. What sort of problems did these owners have with the rudder?
  12. Should be a great boat to sail solo. I do a lot of single- and two-handed on my J/111 and all is easy to manage, including the big gennakers. However, a good auto pilot is a prerequisite!
  13. I have my Expedition data folder defined on Google Drive. So, as soon as the PC that runs Expedition connects to internet, all expedition data in synced to the cloud so I can access it for analysis everywhere.
  14. On the internet you can find ORC speed guides from Farr 40 and 30 as well as First 40 and 35 which include leeway as well as heel. From these figures I calculated what the average K should approximately be for the beat angles of these boats which is a value between 7,5 and 8,5. Given the target beating heel, this gives a leeway between (approx) 2 (TWS=6) and 4,7 degrees (TWS=20) which is in the range that is also calculated in the ORC speed guide.
  15. It's from NKE (which is actually an Airmar model I believe, but I don't know which model)
  16. I use an ultrasonic speedo which is very lineair accross a wide range of BSP. However, when heeled I apply a correction up to -3%. This is on a J/111

    In my case the tackline is about twice the length of the boat. Streaming it in the water not only prevents it from tangling itself, but also makes the release of the tackline go very smooth even if the gennaker is under full pressure.

    I frequently sail my J/111 solo and with winds over 15 knots the letterbox is absolutely the safest way to douse the gennaker. Under 15 knots there are other alternatives like a luff drop into the forward hatch or just douce it under the boom into the companionway. A few things I do for the letterbox drop: - You can walk the lazy sheet around the headstay and then in between the foot of the mainsail and the boom. Then use this lazy sheet to pull the gennaker towards you until you can grab the foot. I don't prefer this method as first of all it is less safe to walk the sheet around wh
  19. Sailing short handed I always stream the tack line in the water behind the boat when dropping the gennaker. This not only prevents the line of become trapped, it also 'damps' the sail movement when blowing the tackline clutch.
  20. Why have a trip line running on deck if you can just blow the tackline instead? You only need to make sure your tackline is long enough.
  21. It's a useless boat: you can't cruise with it, you can't overnight in it, you can't go offshore and it's still MUCH slower and more expensive than a kiteboard or windsurfer.
  22. And on NKE instruments the TWA is without leeway. On new boats the BSP is always calbrated to please the sales department.
  23. No, what you read is correct. The Sailmon manual gives a good explanation on how back-calculated AWA/AWS is derived. Read page 18 and 19: https://sailmon.com/wp-content/uploads/2018/10/Calibration-Manual-and-Data-Reference-Rev1.6.pdf B&G and NKE do something similar (at least in their higher end systems).
  24. And the better instrument systems do back-calculate AWS/AWA from TWS/TWA..... So if your TWS/TWA is not well calibrated, your AWS/AWA isn't either!

    Are you sure the 121 is heavier than the 120 ? In the ORC database there is one 121 registered at 6356 kg. The 120's in the ORC database are somewhere between 6500 - 7100 kg.
