*"The Mast Saver 2000 is probably the new staple moving forward for all 9 million sailboats currently in service."* Nope. The vast majority of us have more sense than to use in-mast roller-reefing in the first place. It's not a "fail-safe" technology. It "fails-dangerous".

Those gaps are designed to collect highly prized fishing line. You can harvest that line monthly and sell it to pay your moorage.

[@faksen13]

And giving fishing line space to enter between gear housing and prop = destroying water seal so water can enter gear housing and mix with the oil and thereby give Volvo dealers work.

@Eric E As Mads is now coming to understand, why people that have been around boats for a few years cringe, and start thinking of keel hauling, anyone who whispers silicone, and boats. The cleanup to redo it properly afterwards can get a little tedious (to painfully tedious, oh glorious sanding, before and after chemicals), those of us who have had to repair previous owners mental lapses, think of keel hauling with the engine in gear. Why should the barnacles have all the fun! There are plenty of sealants/fillers, that clean up a lot easier. Best wishes, stay safe

I owned a Warrior 38 - an earlier version of Athena, probably a prototype, She was called Nademia. I owned her for 10 years (1989 to 1999).....I found that under sail, Nademia was at least half to a knot faster once I fitted a Volvo folding prop - the difference was amazing....and there was still plenty of shove in reverse. On a later boat I fitted a Brunton Autoprop - which self adjusts its pitch. Even better !

[@farrellko]

Agreed. Fixed prop is a mistake, even on a cruising boat.

[@luisgirado2893]

Hello Mads, Thank you for your excellent video and humor. I've been thinking about your mast repair and arrived to the conclusion that I would NOT use the main furling. Your system is not going to allow you to reef the main if you do not have the wind on the nose because the main rubs against the edge of the mast rail, where it exits. On top of it, you have leave the cockpit and go to the mast to roll it with the handle in the middle of a blow. No a good setup for safety. Best would be to upgrade to a regular sail with lazy jacks and a simple reefing line to the cockpit. The boat sails MUCH better with regular or full batten main sail and the reefing is done almost anytime safely. Good luck!

[@jhone5244]

Is your new mast saver going to fill up with water ? It may need a drain hole.

[@Cptnbond]

Regarding the water strainer, it's a good safety practice to ensure it is not mounted below the waterline. If the plastic lid accidentally is cross threaded and this causes it to lock up without seating properly although it could give the impression to a person not familiar with such things that it is properly closed. This will quietly sink the boat if left unattended. It's hard to guess in Athenas installation were the waterline is, but worthwhile to double check.

[@stevenr8606]

That's why you have a thru-hull closing valve along with high water alarms & bilge pump(s)

[@MrGSegrest]

I believe he has it mounted above the water line. At least Mads planed it that way last week.

[@kapow1324]

a good point...worthy close attention. The install prescribes the base of the strainer to be 100mm above, but no more than 200mm above, the static waterline. We re-measured this several times during our recent install of a D240. Comparing oranges with apples here...but our waterline looks higher in comparison to Mads' engine and strainer sweet spot position.

[@Asteroid828]

Great video as usual Mads. One small thing, whilst you are out of the water do yourself a huge favour and fit a rope cutter. Not cheap but with all the fishing and pot buoys around you will be a lot more relaxed approaching land, especially at night.

[@airlife7943]

Regarding the corrosion of the mast, you can make plastic bushings that surround the screws and avoid the contact of metais, as if they were straws.

[@bootrenovatie4526]

Mads, the gaps and the plastic ring between the prop and the zinc + propnut are to prevent galvanic corrosion. The hub inside the prop looks aluminium but is sythetic. All to prevent corrosion. This is also why the propnut is replaced by a plastic/bronze version. The plastic ring is the same material as the flappy bits vetween engine and saildrive. Your installation is correct now.

Link for Monel/ 400 Nickel fasteners www.mcmaster.com/fasteners/material~400-nickel/ You should check with a prop shop and see how much it cost to refurbish the old prop, it would be a good idea to have a dependable spare prop. They can press in a new inner hub, for lack of the correct name of the part, and remove the corrosion then repaint or powder coat the old prop. Everything about the old prop looks like it is a better-made product than the new one so if it can be put back in good condition it would at least appear a sound idea. For any of the Monel, also called 400 Nickel, fasteners, you might look up McMaster Carr on the internet they have an online catalog. If they don't have it then it probably doesn't exist, they are the goto source for materials and fasteners, and just about anything else you can imagine you need to complete a job. If you've never heard of them lets put it this way you could probably build an Aircraft Carrier or a Space Station with everything the sell.

Fantastic videos and a massive help in keeping my boat afloat, THANK YOU! I've just serviced my identical Selden mast and I noticed that your halyard swivel is also missing a plastic guard on the section that slots through the gap in the mast and fastens to the main halyard. This leads to the attachment point for the mainsail head wearing away and I saw yours was quite worn down. Without that plastic Guard, the sail attachment point will rotate against the inside of the mast and bang against the inner slot face...if you know what I mean. You can't buy the part anymore but I made mine out of a piece of nylon. Looking forward to next weeks video. Very best wishes.

Re.. sail drive. The washer is on upside down the two prebent fingers should face towards the prop and then bend the remaining fingers tight against the bolt flats. This is to stop the bolt from loosening

[@jaseastroboy9240]

@Mark. I believe Mads did put it on as you describe. He slipped it on the bolt with the two pre-bent tabs facing away from the bolt head. Then just before he tightens it you can also see that the pre-bent tabs are facing away from the camera and towards the prop.

[@johntremain8403]

Nickel 400 (Monel) fasteners are used in some chemical piping systems like Hydrofluoric Acid. You should be able to source them fairly easy by searching for them by their ASTM specifications: ASTM F467 (Nuts) & ASTM F468 (Bolts).

Most of the other cruisers we meet here in the USA end up motoring/motor-sailing the majority of the time and only truly sailing a tiny fraction of the time. The fancy folding props are usually less efficient under motor and horrible when backing or maneuvering in reverse. Feathering props do better with this, but still they are a lot of extra money for a tiny little reduced drag when sailing. Thousands of dollarsnin fidddly bits getting slowly (or quickly when people don't put the proper isolation bits) dissolved into the salt water... A good solid and cheap fixed prop that has good efficiency under power and especially reversing and maneuvering just makes sense. Hit something with a cheap fixed prop and they are easily repaired or even cheaply replaced if it is too far chunked to regrind A folding prop for a competitive racing boat okay, but they sure don't make sense for a cruising boat, as least nfor people on a budget or would rather spend thousands on something more important/necessary to them.

Extra half a knot boat speed in a force 3. I’d say my folding drop money was money well spent on my boat. I rarely race but cruise long passages. And the sails are usually up if the mooring lines are uncleated.

A half knot? We sail pretty close to hull speed anyhow most of the time once we are out in ocean winds. But you have spent a handful of boat bucks on a complex disposable piece of machinery with a limited lifespan in the water for... reasons.

In real life full-time cruising that money is better spent elsewhere.

‘Good efficiency under power and especially reversing and maneuvering just makes sense’. Well I don’t agree. I’m a sailing boat not a motor boat. Fuel efficiency around a marina or through a lock isn’t a concern for me. I prefer being efficient under sail. Yes there is a second or so delay engaging reverse. If I needed that second back, then I’ve fucked up already. If I wanted to be more maneuverable under power I’d just give up and get gin palace with a bow thruster and a few hundred hp but I don’t. I’m happy taking things slow, using my prop walk and windage to my advantage.

Yes it costs more, but it is will last forever in these applications. Can't wait for someone to make a titanium mast.
