Re: D40P - genoa sheet inhauler

Just add more rope clutches. The mounting hardware for the rope clutches is covered by trim plates inside. The trim is fastened with silicone around the outside. It's a pain to remove and replace, but is completely doable (I've done it a few times on both sides). The backing pads in the deck molding...

Grab Rails (again)

The forum has been a little quiet, so I thought I'd post something. Over the years, we've had recurring leaks around the cabin top grab rails. They get stepped on or just frequently used, and the seal between the teak and fiberglass, or around the screws, will eventually open up enough to let the ra...

Re: Boom height on Dufours, in particular 325 and 34

I can take a measure tomorrow, but our (D34) boom is probably at about 2m at rest. We do use the topping lift rather than just relying on the rigid vang, and I upped the compression on the spring in the vang years ago (added a Delrin block to partially compress the spring).

Re: broken stairsteps

Unfortunately, the wood Dufour uses for the steps has very straight grain, and thus not a lot of strength. We are still working on a "best" solution, but the two we've tried so far which seem to work reasonably well are either: A) Creating a laminated wood step where the grain runs both directions. ...

Re: Generator

Point taken. Totally depends on your boating profile. Around here, we tend not to have long stretches of motoring during most of your cruise. So, the most frequent need for power generation (absent solar panels or a wind generator) is at anchor. At anchor (or under way under sail), I'd rather have a...

Re: Main Sail Identification

Sail numbers are normally assigned by the national racing authority (e.g. US Sailing in the US). You don't usually need to have the boat measured to have sail numbers assigned (particularly since boats may be rated under a variety of different rating systems). There are also one-design classes out t...

I'm not sure about the GL410, but had a heck of a time finding replacement batteries for my D34P a while back. I eventually found the correct battery size (Group 34) and I went with Odyssey batteries (they used to OEM for Sears). The TPPL design charges quickly and has a better rated lifetime than a...

The auxiliary engine isn't a particularly good option for power generation if other options are available. First, the belt-driven accessories won't provide enough load on the engine. Running diesels at light load is both bad for wear and likely to build internal carbon deposits. Second, your aux eng...

Moabi is also sold as African Pearwood. It seems to be more readily available in Europe and the east coast of the US.

It's not that it was mounted incorrectly - it just falls out. We've been fiddling with ours for 14 years and haven't found a permanent solution yet. I'm about to try yet another adhesive on ours. It's a flexible contact cement used in aviation applications which will supposedly hold plastic and meta...

Hi Angus,

If you mount panels in that location, you will need to adjust the boom to avoid putting any shade on the panels while charging. For most panels, shade on any part of the panel will reduce the performance of the entire panel.

Best,
Tim

I haven't found the plywood, but I did make a new panel using marine plywood and veneer. I couldn't find Moabi veneer near me, but got a pretty good match with a mahogany veneer and the right stain.

I don't know (all the hinges on the Dufour seem to be unusual), but I'd be interested in knowing if you find out.

That said I'd consider some other way of attaching the hinges if possible. The screws really don't hold well enough given the weigh of the lid.

Cheers,
Tim

2004 D34 Standing Rigging Type?

We are going to be replacing the standing rigging on our 2004 (2003 build) D34 soon. The current rig is original and now has over 32,000 NM on it. While I'm sure I can figure it out with the rigger next time I'm over at the boat, does anyone know if Dufour used Dyform or regular 1x19 wire for the ri...

Unfortunately, the bumpers from the lazarette hatches and companionway hatch aren't 3M parts. They don't even have anything close. In both cases, height is a critical dimension so that the hatches align to lock. The lazarette bumpers are roughly 17mm and the companionway ones are 21mm. The companion...
