    Thanks guys. This week I will sail again trying those adjustments.

    Yes I did some sailing in the past with 21 feet boats, and once I sailed on the Metiterran Sea as well - always with an experienced captain.

    The rudder did not want to go deeper - later I found that the rubber cord was a bit too tight - that's why I was banging it . No apology.

    Default Sailing practice

    Dear Friends,
    This weekend we had good wind finally. (not unusual in Hungary but somehow there was no breeze at all last month).
    I traveled down to Ráckeve where I have a little land with caravan next to the Danube river.
    It was an excellent adventure to explore the limits of this little boat and the speed it can easily gain if the wind blows with about 20km/h (11 knots).
    Sometimes I heard cracks - probably the mast base and mast partner, I checked them afterwards and everything seemed to be in one piece.
    I almost flipped over a few times - but I managed to avoid capsizing with some lucky maneuvers. Once I had about 50 litres of water coming in the cockpit but it was OK to sail with.
    I have two videos taken by my wife, she was not strong enough to use the camera when the wind was stronger. She was a bit worried.

    This photo was taken 2 weeks ago when we had almost no wind but much fun sailing together with my bro.

    Hi Csaba,

    Did you change the sail? The boom is a lot higher

    It looks like it works OK which is the main thing!

    Well done!

    Hello Michael,
    No, I did not change the sail. I only fixed the boom and the sail a bit higher. It is more comfortable and did not cause loss in performance.

    Hi Csaba

    Just an idea for next year... What do you think of a PDR meeting in Hungary? At this moment I know about there boats in Eastern Europe, you, me and Koala. I travel often to Hungary for model boat races, I just have to find out what papers I need to take the PDR abroad.

    Szia Gyula,
    I definitely agree. This idea had already been mentioned before. We could go to the Lake Balaton or Velence, but I am also happy to host such a meeting in Ráckeve where I have my weekend house caravan.
    By the way 2 other PD Racers are under construction in Hungary. Let's hope if they will manage to join us as well.
    Cheers

    Default Repairing the mast

    Dear boatbuilder friends,
    after the long winter break I decided to check and clean my PDR.
    The mast was stored under a roof where I keep my Eureka and car (see first photo).Attachment 135344

    Maybe because of bad construction, bad weather and because I used it once in rough wind in October the mast looked very awful.

    Attachment 135341

    The staves were torn apart, there were longitudinal cracks all around and some epoxy layers ripped off despite the fact that I used UV varnish.

    The question is what to do. Should I just redo the whole mast? Or can I repair it?
    Nevertheless, I cleaned up the cracks with a V chisel, and I filled up with thickened epoxi.

    Do you think guys that I should also glass the whole thing? Or just sand, epoxi and varnish again?

    Thanks

    Hi Csaba,

    I don't know which is the best as it is hard to know what was the original building and what was from the storage over winter.

    The boat has been sailed OK - so if most of it is from the original building it will continue to be OK.

    But if deterioration over Winter it is difficult to predict if the strength has changed and how much.

    Do any of the joins move or are they all still glued to some extent?

    I would probably remove all the varnish. Sand all the cracks with fresh sandpaper - no rougher than 100 grit, then use the epoxy with glue powder to fill the cracks. Use masking tape so you only get the epoxy mix where it is needed as much as possible - it will save you heaps of sanding.

    Sand it smooth

    Then I would take care of the highest load area of the mast - where it goes through the deck - and glass the mast (6oz - 200gsm) from the base up to a metre above the deck.

    Then I would check that the glass tape at the top of the mast is OK. Replace if necessary.

    Put a piece of 2" tape wrapped one time around the mast. every 400mm up the part of the mast that is not glassed. This reduces the risk of the long glue joins splitting the full length of the mast. Any splits will stop.

    Epoxy mast, sand lightly and varnish.

    Default Sailcloth question

    Dear Boatbuilders, dear Michael,

    I am planning to try my OZ Racer with lugrig. I have sewn the sail which is made of spinnaker sailcloth (it is top quality - that's what I had at home) - I made some extra-reinforcement knowing that the sailcloth is not exactly made for being a mainsail. I think it will work fine; Would you agree? Do you think some more reinforcement needed?

    Attachment 165948 Attachment 165949 Attachment 165950

    I plan to have the sail loose footed - would it make any difference in performance?

    Howdy Csaba,

    If you got the sailcloth for nothing it is worth the experiment.

    Generally spinnaker cloth is both too light and also too stretchy for jibs and mainsails.

    What size boat did the spinnaker cloth come from?

    Loose footed is fine. Main thing is the boom needs to be a little stiffer - this is contrary to the advice of sailmakers, but it has been shown to be the case in reality with these boats.

    Best wishes
    Michael

    Thanks Michael, yes, I got the sailcloth for free. I will report about my experiences.

    Have a look at my photos that were taken yesterday during my spring clean-up, where I removed all my boats from the winter storage and got ready to list up the to-dos.
    Cheers

    Thanks Gyula, the photos were made by the most enthusiastic Hungarian OZ Racerer Jenő. Lake Balaton is not an easy place for sailors but he made it.

    With this photo I am also wishing you a Happy New Year. The new spinaker sail works fine.
