    Arafura Cadet For Sale

    I am interested in an Arafura for my grand children, What is the condition of the one you have, and how could I get to see it. Is it with or without its own trailer (not that that is too important as they can be "piggy backed" quite well and even "roof topped" Darryl

    Pity, I am interested but it makes it a little difficult when I am in Adelaide.

    Rudder Design

    To balance the rudders there needs to be between 6% and 10% of the surface area of the blade (that is in the water) in front of the pivot axis. This applies to all rudders.

    Alpha omega repair?

    Apart from a few early AO 4.4’s which were fitted only with “bungs” we dispensed with the bungs (the quickest way to fill up a cat with water is to forget the bungs) and fitted a hatch on the inside of each hull between the rear beam and the transom with the top of the hatch approx’ 50mm down from the deck line. This enables any water (should only ever be a small amount) to be sponged out of the hull. To search for any leaks there should be a “breather” hole (approx 1/8” diameter) in the deck of each hull, in the middle of the deck, usually just behind the rear beam or just behind the centre/main beam. Close the bungs then with your mouth over this breather hole blow into the hull. Have someone else going around the hull while you do this and they can generally hear even a tiny pinprick hole whistling. The amount of leaks and their size will depend on how hard it is to blow up pressure in the hull IE the easier to blow the more or larger the leak(s) the harder to blow the smaller or less the leaks.

    Alpha omega repair?

    I have just viewed your photos and it is very difficult to form any opinion as to what has caused it from them. Off hand I would say that to conduct a repair I would sand back the “bulge” (whatever it is?) from the outside of the hull and treat it like any repair IE sand back to the form a slight hollow, apply glass and resin to the area, fair it back, gel coat, fair back and cut and polish to finish. That particular area on the AO’s is very strongly built with an insert of aluminium plate glassed into the hull on the inside to support the chainplate loads.
