  1. Mousing line in place!

    4 x 3 m lengths of 16 mm plastic piping made it possible as it was quite easy to push the plastic tube all the way from the bottom of the spar to the top. Cutting the end of the leading tube to a sharp point helped avoiding catching on rivets and bolts. A 4 mm hole drilled near the tip was used to attach the mousing line and the sheave at the mast top was removed to make access easier there.

    The rest should be routine work (famous last words?).

  2. Good idea, only snag is that there is no way to get to the top of the mast to feed bicycle chain into mast. I have even saved some worn out bicycle chain in case I may need it for this purpose.

    Main idea right now (before going to bed) is to get some cheap plastic piping (16 mm outer diam, 3 m lengths) and push this in from the bottom end of the spar. I hope I can figure out a way to attach mousing line.

  3. Tried the shop vac idea tonight -- didn't work. At best I got about 2 m in. The tube is fairly clean inside but there are some obstructions including the jib halyard and the spi halyard. I could remove them but progress stopped before I got to where they could obstruct. Also, there are a number of leak points. I tried to deal them with tape but it was not good enough to make a difference.

    I could push rods or tubes in from the bottom of the spar but how do I get to the mousing line at the top?

    Fish tape or fiberglass snake might work but I can see how they may act up on the way. There are rivets and the odd bolt to catch on and once that has happened the tape will buckle and...

    Rods or tubes sounds better, at least right now. I need 12 m plus, as mentioned above, some way of making the mousing line hitch a ride.

    Thanks for the ideas so far. Keep them coming.

  4. Planned to rig the boat today but things did not according to plan. I use the boom, main sheet and main halyard to raise the mast. The tail of the halyard broke. No one hurt, nothing else broken as far I know. For the first time since I built this rig I am in the situation that here is neither halyard nor pilot line where the main halyard should be.

    When I built this rig I was working in a workshop with an air compressor so I simply blew pilot lines fitted out with simple drag devices down the mast tube.

    Since the mast is kind of horizontal gravitation will not be of much help and compressed air is not available.

    What are my best options? Pushing a wire down the mast tube? Maybe I could use a vacuum cleaner to do the same thing I did with compressed air?

    TIA

    PS here is what lowering the mast looks like.

     

  5. Here in the Northern hemisphere it is time for maintenance. One of the items on my list is to re-sleeve the main halyard. It has an 8 mm Dyneema core and the sleeve is busted where it sits in the halyard clutch.

     

    The current sleeve extends 1.5 m above the clutch for reasons that do not apply any longer. Hence the question: How much sleeve is needed above the clutch?

  6. I hope the outer diamonds are fixed to the spreader tips. It is not unusual to overlook this important detail. It does not replace an inner forestay but is important anyway.

     

    The actual staying does not look overdone to me but there is a lot of other things adding clutter and drag. Lazyjacks, halyards etc, some of which will be out of the way when sailing.

  7. Somewhat related: Many years of marine biology research resulted in finding a substance that 'tells' barnacles "not here" without harming them (it is claimed). Now this substance is used in at least two brands of antifouling paint. The Danes have just started marketing their paint to the pleassure boating market -- at least here in Sweden.

     

    The substance they use is marketed by this company by the name Selektope: https://selektope.com/

  8. Well, there is always that thing called fire...

    Happened to Swedish Seacart 30 some years ago and swimming for the shore wasn't an option. I don't remember what saved the crew but it was not a pleasant experience.

  9. So to sum up: No good.

    ?

     

    Myself thinks:

     

    * Why only 5 m BOA (I fly a hull in 10 knots of wind with me on the windward side)?

    * Will that centre beam really take the fore-stay load with low enough deflection?

    * Low, inverted bow profile is very 'modern' but also very impractical.

    * Surprisingly high weight estimate for being found in sales material. Maybe honest :-)

    * That centre beam is designed with no intention to use it for sealing the foot of the sails. A missed opportunity.

     

    /Martin (living in Sweden so buying a 8.5 is not in the books and besides, I am still pretty happy with my old Spyder -- which does not rule out day dreaming/sketching in long winter evenings...)

  10. Interesting, Brett Burvill's older brother Hayden won a regatta I helped arrange in Sweden in 1990. I believe Brett was one of the very first people to experiment with foils on Moths.

     

    Who is building Tornados these days?
