      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

Anchoring a Sprit Boat

Recommended Posts

What's it like to anchor a boat with a big sprit, like a J/120? Does the anchor rode get all messed up with the sprit? Are there techniques that people have figured out to avoid that from happening? I'm not talking about anchoring for lunch, but rather serious days-on-end anchoring when long-distance cruising.

We anchor our 130 all the time, no problem.   Great cruising boat, we used to carry a 44# bruce on a roller, I've since gone to a Fortress that I store on a bracket in the sail-locker aft.  We only use 30' of chain and 300' of rode to keep some weight out of the bow.    The problem with a sprit and anchor is not the anchoring part, it's keeping the kite clear of the anchor when hoisting or jibing, this is why we stopped using the roller.

I anchor our 109 all the time, the anchor when stowed was too close to the sprit when extended. I re-did the plate holding the roller and now there is no problem. There was never any issue with the rode snagging the sprit, we even extend it at night to get it out of the v-berth. You do need to watch the kite closely.

A bigger issue is how much these boats move about in a blow at anchor. I am going to try a riding sail before next cruising season. If anyone has tried this, or has other ideas, I would like your input.

My experience with riding sails: Completely worthless. Maybe worse.

If the waves are small, and not much rain, just wind, anchoring by the stern completely stops the tacking at anchor.

Hanging junk in the water off the bow to create lots of drag can help. Spare anchor, buckets.

Dual anchors or stern anchor. Take the headsails off the furlers.

Big downside of performance boats.

If there's a bit of current, a bucket or two streamed off the stern works pretty well to stabilise things

There is a good article on the J/30 website from 1997 about building a parking sail.  It was effective on my J/30.  I'm thinking of doing the same thing for my J/109.  I have plenty of old sails I could cut up to make one.

Can you post some pictures of the modified plate please?

I know what you mean. My current boat (a Wylie 34) sails to her anchor A LOT! A friend who did a five-year cruise in a sister ship - mostly in the South Pacific - told me that using an all-chain rode eliminates that tendency, although putting on an all-chain rode is a big commitment.

The original one piece plate and roller are on the left. I used a Mantus roller and new SS plate (center) to move the anchor to port a bit to clear the sprit. The cardboard template is on the right. The original set up was strong, but not sized properly for any of the modern anchors.

Here it is all installed. The photo perspective makes it look like the anchor is way out front, it is not. It took a lot measuring to get the set up to clear the bow, sprit, fuller  and still work with the windless. For cruisng it has been great, the anchor will self launch, and it all still unbolts for racing if needed. The rollbar anchor helps reduce snagging on the kite, but the point of the anchor can still grab the foot if we are not carefull.

Thanks - Some configuration differences between the US and European built J/109.  The US built boats have chocks port and starboard just aft of the forward stanchion for the bow lines and cleats just forward and outboard of the aft stanchion.  It doesn't appear that these would cause a problem with the anchor system you installed.  You have a Harken Mk IV Unit 1 furler.  A picture I have on Google photos from when I did the purchase survey in 2013 isn't the best, but you can see it here.

My hull 266 was built in 2005 has a Harken Mark III Unit 1 furler.  Probably just Harken updating the design during the production cycle.  Where are your bow cleats located?

My hull is 375, it was built without chocks. The cleats are in the same position as yours. So far it has not been a problem since we are fair weather costal cruisers.

I am not the original owner so I am not sure what was standard from the factory vs specked by the first owner. He had set the boat up for day sailing and light cruising rather than racing, but I doubt he made any changes that would upset the OD rules.

"Anchor under foot" is the old term for dropping a spare anchor to the bottom with limited slack so it drags.  Really helps reduce swing, but I worry about dragging around an expensive anchor that can get hung on a foul bottom.  A trick solution would be a bag made out of large mesh, like a fishing net, that you could put a large rock in, maybe.
