Is this a 4 stroke engine, or 2 stroke? I used to have the 2 stroke on my F27.

Mal

Christian;- When rudder is held in by the tackle, the eyebolt goes up into the little tunnel in the transom. Therefore, the new eyebolt will need to be in exactly the same position as the old one. The eye needs to be horizontal on my boat to fit in the hole/tunnel, and the eye is actually bent upwar...

Mal

Steve B;- forgive me, but I prefer my method:- no tying extra bits of line onto masthead and chair, so less to go wrong. If you messed up cutting the end of the halyard and dropped it, you're stuck up at the top of the mast. If I messed up cutting the halyard and dropped it, I could still be lowered...

Mal

You need a wire sewn into the luff for assymetric to work on a furler. Don't know what sailmakers use;- maybe can be done with Dyneema or similar these days?

Ask your friendy local sailmaker.

Mal

As per earlier posts, wanted some way to get to top of mast on my 920, to cut off the last couple of feet of halyard, and re-tie. Dawned on me that as a two-part halyard, could go up in the bosuns chair using halyard as conventional single line, by tying a bight/loop in it. Hard work for the person ...

Mal

I'm sure you mean roller furling, not reefing. I've got a single line roller furling gennaker on my 920;- drum at end of bowsprit. Came with boat when I bought her second hand. Because fabric of these kind of sails is relatively thin/light, you need lots and lots of rotations to roll the sail, and t...

Water tank lid in my DF920 is indeed clear plastic. When I see muck in the tank, I don't/can/t do anything about it, because would need to undo dozens of screws. I'm going to put a waterproof circular hatch in the plastic lid, so that access will be easier. Might be an idea to do that initially if y...

To answer my own question;- can't find an alternative refrigerator. Vibocold still have one, and are very helpful, but by the time I add on VAT, carriage, and customs handling charges, price comes out at around £600;- ridiculous money for a little fridge! Have instead used some Kingspan foil faced 5...

Mal

Mr Scweitzer;- Have just found my old eyebolt off my 1998 DF920. Typical;- I stopped looking for it after sending a post yesterday, and today it turns up whilst I'm looking for something else! It is 4 inches long from the underside of the flange to the end of the thread. Overall diameter of bolt inc...

Mal

Have hunted high & low for my old eyebolt, but can't find it anywhere. sorry!

Mal

I replaced the rudder of my 920 when the old one broke. I might just still have the old eyebolt out of it kicking around in my shed.

I'll have a look over the next couple of days, and let you know if I can find it.

The Vibocold F35 refrigerator in my 1998 DF920 is kaput. Vibocold no longer make this model, and the replacment CF35 is too high to fit in the drawer under the cockpit sole. Vibocold might have one damaged f35left in stock;- they are checking, but if not, any ideas for a refrigerator that will fit? ...

Mal

Thanks Diana for all the detail;- much appreciated.

Mal

Diana;- did you use the DF plastic bearing, or have a bronze one made? If the plastic DF one, did you get it machined by a machine shop & take the rudder shaft with you to make sure it fits? Got to do mine soon! Bit of a pain that you've got to have the boat out of the water to do the job, as ne...

Mal

Might be RWO's auto-release. Check dimensions.

Mal

My tramps are coming up for replacement in the next 12 months, & I would like the option of a more open weave. The DF tramps are really very good in many ways;- they feel safe to walk on. I had an F27 before, and tended to go across the tramps on that bent double, with hands walking as well as f...

Mal

Is this the one that later capsized?

Awesome picture!

Mal

I've now changed the float winching line on Pelican to 8mm uprated racing Dyneema. Makes a huge difference to the effort needed to winch floats in and out. I notice, though, that when applying the Easylocks they seem to allow more line through before they grip. Don't know yet whether this down to th...

Mal

Anyone tried/seen the new Selva Pirhana 9.9 hp outboard? Is a single cylinder 4 stroke, and available extra long shaft. Selva claim it is around 10 kg lighter than the competition. In theory a single will be 'lumpier' than a twin, but depends if counterbalanced well? I noted on a Honda that I had, t...

Mal

I have DFD920. My main halyard has not broken, but these posts make me think that I should at least shorten it at the masthead. I seem to remember a post some time ago that suggested it was possible to go up the mast on the main halyard, then lash oneself in the bosun's chair to the masthead, allowi...

Mal

Peter;- Thanks for the detailed report. Will be useful info for those like me who might have the job ahead of them. Regards, Mal

Mal

A friend of mine has a J28 or whatever it s called, and he takes the mast up and down on a regular basis using an inverted 'V' pole arrangement fixed just forward of the mast. Apparently it is common practice with this class of boat amongst the owners. The feet of the V are fixed to the deck edge ju...

Mal

Pippo;- I have done towing of Telstar 26, and Farrier F27. It is always tempting to get something as small as possible to tow;- rest of the time when not towing not too expensive to run! Pulling the boat is not the problem;- its stopping the thing that's difficult. Also, if the boat/trailer set up i...

Mal

Roby;-

Height of stand is 1 meter. Is shown on the drawing?

Mal

Mal

Buckle Roger;- I like your idea of drilling another hole in the tube to hold the floats further out;- better than keeping them out with tension on the outhaul/inhaul line. Following an earlier post, I've already bought uprated 8mm Dyneema, but have not fitted it yet. Hope this makes winching float i...

Mal

Do you know something that I don't? A '32' on the way?

Mal

Mal

I have a DF920. In my experience, you need both jib and main to sail effectively upwind. My jib haliard broke once when going upwind in a good blow, so I tried sailing on main alone:- virtually impossible. However, will go upwind on jib alone, but obviously not as close to the wind as you could with...

Mal

Ipe, I like your idea of using 8mm line instead of 10mm;- the sheaves look 'too full' of line, and are obviously right at the max size they will take. Have you used an uprated 8mm of some kind to be sure its strong enough? My floats go in and out very easily when out of the water, so I don't think I...

Mal

Chris;- 3mm wall thickness

Mal

Anyone got electric winches on their 920 for winching in the floats? Were they an option on bigger DFs like DF1000? Anyone tried alternatives like electric 90 degree drills such as the Milwaukee 24v fitted with suitable bit? Have seen some posts on other sailing forums about them, but a bit inconclu...

Mal

Good idea Extravert. You can also hang a fender down the inside of the float hull before winching in, and this cushions things to some degree. However, the damage is mostly caused, I think, by up and down motion of the float, rather than in and out. I don't know if either of our solutions helps ther...

Mal

Thanks extravert, I do use Duralac. Pity Profurl apparently didn't!

Mal

I agree with Ipe;- I have a 920, and get 90 deg between tacks on the compass.

Mal

Had trouble with my jib reefing gear this year, and found the Profurl gear very difficult to dismantle. Where sail extrusion goes into fatter aluminium 'tube' on top of the reefing drum, it is held by two screws;- one with a head, and another a grub screw. Grub screw would not come out;- tried freei...

Mal

Roby;- It is a little difficult to understand your rudder problem exactly due to the translation into English. I think that you say the screws holding the bottom rudder bearing were 'soft'. By that I assume that the bottom rudder bracket worked loose from the hull (is held by two screws), and that t...

Mal

What do others use to lubricate where the beams pivot on the circular tracks on the float decks? I've always used 'Sailcote' teflon spray, but have run out. Not sure it was brilliant? Now can hear juddering from bearing surfaces as floats are wound back in. DF manual suggests using wax. What wax? Or...

Mal

Thanks Mario;- I'll try that one.

p.s. Can you recommend any good life insurance companies?

Mal

You are going to think that this is a very silly question;- I would like to change my main halyard end for end, but don't want to take the mast down (cost!). As halyard is 2-1, is tied at top of mast. Can only go up mast on main halyard, so how can I change it? Any brilliant ideas? Safe ones, that is!

Mal

Has anyone else fitted a bow roller for the anchor? Whilst pulling up anchor from starboard aka, nowhere to quickly cleat off? Anyone fitted a cleat in that area as an alternative? Suspect deck moulding not strong enough to take a cleat in that area? Standard arrangement of cleat on main hull bow, a...

Mal

My 920 had water in those under-window lockers both sides. Removing the windows and frames, then re-sealing fixed the leaks.

Mal

Mal

I used the dimensions from Quornings of their yard trolleys for supporting 920s, and have had made front and rear supports to go on hard standing that support the boat in the correct places. I have designed them to be easily dismantled for transport so that they will fit in a hatchback car. Have use...

Mal

The previous owner of my boat pointed out a small repair on the underside of the main hull overhang, i.e. directly under the saloon side lockers below the windows. He had been moored folded against a dock when a large fishing boat went by at speed, and the resulting wash made the float hit the under...

Mal

I also have an ST40 wind instrument on my 920. Was playing up, so I bought a new masthead unit. Works OK, but as originator of topic states, wind direction not particularly accurate. I also would be very interested to know if anyone has succeeded in fitting an ST60 instrument:- feel sure I've seen a...

Mal

Andrew H, I notice you mention Pembrokeshire as your sometimes location? I'm not far away in Swansea;- nice to meet up sometime? My email is malrat@btinternet.com

Mal

Jacob;- you are right. At forward end of the cockpit lockers with the float jammers, there is a half bulkhead forming a step. The mink has been getting over that step, and then down into the locker under the cockpit floor that has the sliding drawer and refrigerator. I will have to make and install ...

Mal

Thanks Jacob;- I'll have a look at the boat tomorrow, and see if that might be the route that the mink has been taking.

Mal

Mal

Bo;- thanks for your post. There are 3 questions that I would like answered;- two in my last post;- 1. Decent diagram of rear beam block line threading 2. Should the winching line by 10mm or 8mm 3. A previous series of unresolved postings about correct method of tensioning water stays on 920;- lots ...

Mal

Have had either a rat, but most likely a mink, get onto my boat. I keep it in a marina, and keep cockpit enclosure up. Found droppings and nasty smell in cockpit a couple of weeks ago, so left enclosure down, hoping visitor would go away. Unfortunately, visitor has managed to get below somehow, and ...

Mal

Diagram from Quornings as posted by Bo is taken from Owners Manual. It really doesn't show the block threading in sufficient detail for such an important safety matter. Any chance of Quornings taking half an hour or so to do a decent diagram for us owners, please? (The drawings probably already exis...

Mal

Further to my earlier post, anyone got any idea of luff and foot dimensions for spinnaker 920 Cruising, please?

Thanks
