I just did this replacement again, and decided to use 10mm (3/8”) line. I tested it in the jam cleat and I think it will hold better in the cleat than the 8 mm line (specified in the manual) my boat came with.

How many amps does your refrigerator draw? Assume a 50% duty cycle (compressor on/off) x 24 hours. Then consider the rated power of the solar panels you need, and factor for the number of hours of peak sunlight per day, shade from rigging, clouds, and latitude. Most “danfoss” type small refrigerator...

Call Richard at Dragonfly USA. He can probably advise you.

Does anyone know where to buy a replacement for the faucet used in the 1200 aft sink?

Double Horizon

I think you might find it is not rewarding to race in the same around the buoys event with monohulls. There is no way you will ever get a fair rating, and the vast difference in performance increases the risk of collision in tight places.

Double Horizon

You nailed it - the mast compression would double, as would your halyard and sheave loading. You would also need to go up a size in your halyard line. These are critical components. You payed a lot of money for your boat and you should not cut corners on a proper halyard, imho.

Double Horizon

Ok, I understand that 2 things important: - Spinnaker halyard to the end of the aft cross beam on the side to be repaired - Boat must be UNFOLDED Both AMAs unfolded? Will do that way for sure, even I don't really understand why it's son important the unfolded condition. Thanks again. Before I expla...

Double Horizon

I just read your post again - NO NOT "stern deck cleat"

You MUST attach to the outer end of the cross beam while the boat is UNFOLDED. Don't even think about trying this unless the boat remains unfolded.

Double Horizon

(edited) NO NOT "stern deck cleat", you could keep the mast up by securing the spinnaker halyard to the end of the aft cross beam on the side to be repaired, in place of the backstay. I have replaced backstays that way, one at a time. The boat MUST remain unfolded during his operation. (Ma...

Glad you are safe! Good advice. On my boat I do not leave the cockpit without a lifejacket or inflatable belt pack, and that is the rule for my crew also. Many times (especially in nice weather) people do not follow this rule and I remind them, saying "you forgot something" and hold the li...

You will need to grind the fiberglass from underneath until you get to the metal frame that the M20 bolt is welded to. Try not to go all the way through to the outside. This is a big dirty job. Best to dismount the ama and work while it is on its side, wearing protective suit and high quality filter...

Sorry so slow Larry, been overwhelmed with a few things.... I ran the 1/4in dyneema, threaded through the net right up the OEM channel. Before running the combo up the channel, I placed a 1/2in outside diameter x 1in long with 1/4in interior diameter nylon spacer (home depot) at the forward edge, a...

Dear All, is there anybody who can suggest the name of a reputable supplier of double braided leaded anchor rope for a DF 1200? Liros makes it, but the end is finished in a thimble that won't go through a windlass of the 1200. http://www.liros.com/en/products/productfinder/details/detail/liros-hand...

From what I've heard the excavator would be the least of his expenses by the time he hires consultants to do an environmental impact statement and gets approval to dredge from local, state and federal officials?

In a tidal creek, you'll find the 920 is also quite maneuverable. There is (or should be) a linkage between the outboard motor handle and tiller, so the outboard turns when the rudder does. The amas draw only a few inches of water.

Double Horizon

I doubt jamming would be a constant issue. But it might happen. Would it be possible to set a mooring nearby in deeper water and keep a dinghy at your dock? If so, that would be a better solution.

Double Horizon

Hello, I've read with some concern about issues with the centerboard downhaul jamming when a boat is repeatedly grounding at a low tide mooring. I'm thinking about buying a 920 that would be kept at a dock that rests on a mud flat 2 hours out of every 6. The boat would face up a slight grade, gener...

Hi Steve - would love to see a picture or two showing how you mounted that much solar on a DF 1000.

Hi Joe -
It's not clear to me what you're asking. Can you clarify any questions?

Double Horizon

One of the display heads should be mounted with 2-sided tape or Butyl sealant, so it is stuck on (not screwed from behind). If you can figure out which one you can gently pry it off (using a plastic scraper blade, not metal). Once you have one display head removed, you will be able to reach inside a...

Double Horizon

Some people may disagree with me, but I do not think any Dragonfly is an ideal boat for a novice, and especially not a novice family of 5.

There are many simpler boats that have more room for crew, and are more forgiving of mistakes.

I sailed the DF32 for a day sail this summer, it was a 2-year old boat. It sails very nicely and it was diesel. I agree with George about the advantages of diesel.

Hi Robo Congrats on your DF 1200. I'd be happy to help you out with any information you need. I'm a DIY type and know a lot about these boats.

Also, I keep one bridle for travelling (cruising) and the other stays on my home swing mooring, which is permanent. The home mooring bridle has stainless thimbles at the mooring end, and attaches to the mooring with 5/8" galvanized bow shackles. It also has floats. I use a multihull bridle plat...

Thank you Larry. This is an awesome and very detailed explanation. F It's my pleasure Fabio. Winter is a good time to learn splicing.

Double Horizon

Thank you Larry. What size Dyneema do you use? Do you use the eye bolt on the bow of the ama to attach the end pf the bridle? Do you tie a bowline knot or use another snap hook? Thanks I use 1/4" Dyneema single-braid. The loops at each end are made with a Brummel Lock Splice. I make the loops ...

Double Horizon

I do similar to George. To attach the temporary bridle, I use a short loop of Dyneema in a Prussic knot, for each bridle leg. The ends of both bridle lines each have a large Wichard snap hook, which is used to attach to the Dyneema loops. A Prussic knot does not slide under load, and it slides easil...

I think it's great that you want to charter and take some lessons. I would suggest that your first charter be a crewed charter, and tell them you want to be hands-on crew so you can gain a little bit more experience and learn to handle larger boat. Your first venture into the Caribbean should not be...

In general, and this goes for ANY sailboat: 1) Trailering (and launching only when you sail) is not a good plan. I've tried it when I was in my 20s with a smaller, simpler boat and that lasted only one season. There is too much time and effort involved in rigging and de-rigging. There are people who...

I have a job where I can only take one week vacations far apart from one another. That's your issue. If you could take 3-6 months you could make it an adventure.

Is soft paint the leaching type of paint? I used it once and will never do it again. I got that color on everything. It got to ropes, fenders. And from that to other stuff. It was a mess.

1) Bottom paint -- I concur with George. 2) Haul out -- Buy proper stands or a trailer. Just say NO to saw horses. You can't just put stands anywhere on a Dragonfly. They must be under the water stays (where they connect to center hull) or along the centerline of center hull preferably within a foot...

The pedestal is called the Lewmar Cobra Monarch, and the ones installed on the 1200 were chain and cable drive. This is a link to a document for the Cobra Monarch (but the inner workings do not apply because this diagram is shaft drive). https://www.dropbox.com/s/463hjg26d0q6cug/Whitlock%20cobra%20m...

Even though Whitlock was bought by Lewmar, the steering systems were originally made by Jefa about 15 years ago. The Whitlock pedestal installed in the 1200 looks exactly like the Jefa RP300 model.

I cut the nets the same size/shape as the old nets. The 1/4" dyneema edge was then woven through the net edges. The ends of the dyneema were then tucked into each other (chinese finger trap) then back out, leaving the bitter ends exposed. I could then adjust the tension by tugging on the bitte...

TC is the one with the new nets. Mine are original, but I personally resewed them with GoreTex Thread. They'll probably last forever. I will probably follow TC's lead on replacements after I see his. His dog will probably vouch for their comfort! Yes I had mine sewn with Tenara thread also, and rec...

I'm curious who sewed your new nets. Was it a local canvas shop or sail maker? Or did you use a net specialist?

I think you are right Stefan. I should have considered the rig.

One thing I would NOT do is allow the salvage crew to decide how to pick it up. The owner MUST supervise the workers. If you leave the scene it will end up in the hands of the insurance company and the salvage operators. They do not put the owner's best interests ahead of their own. There is no sing...

IMHO, 800, 28 and 920 are for protected waters. 35 and 1200 are blue water. 1000 is probably an overbuilt safe sturdy ocean boat (despite TC's desire to lighten up).

The 1000 folding mechanism is not as strong as the 35 or 1200. The later designs are more rigid.

Chicken jibe is the only way to go if you don't want to break things.

Dangerous for crew too, if you get hit with the boom or swept...

I can see how the pin can spread the resistance forces to more parts of the base. However, in viewing the picture it appears that a tremendous amount of force pushed aft on the forward face of the sheave box. The only way this would happen (I think) is if the owner lowered the mast (tilting it forwa...
