    Mull of Kintyre is actually the tip of the Kintyre Peninsula and is land. The channel of water is known as the North Channel and connects the Irish Sea to the North Atlantic.

    Hi

    Ardupilot supports boats, I have only used it with aircraft but there is a lot of information available applicable to boats on the internet. This is a good starting point.

    Hi Lew

    You are correct but I was referring to the option where they are mounted below the hull, as per the pictures.
    There are two types of Kort Nozzles, accelerating and decelerating. Both, as you pointed out, have an aerofoil cross section, the first the curvature is in the inside to accelerate the water flow and the second it is on the outside. The other fact is that the propellers should be designed for Kort Nozzles. The other point of interest is that there are two main types from a steering aspect, fixed with a conventional rudder and moving with one or more rudders attached to the nozzle.

    Hi Lew
    Vegetation could cause problems but there is normally a partial shroud around the vanes. As draught, they are no deeper than Korts Nozzels or Azimuth Drives. The only thing putting me off is the price. 40 years ago I often went out on the harbour tugs in Cape Town in South Africa and all of them had twin Voith Schneider drives, their ability to maneuver was exceptional.

    I have been looking at Kort Nozzels, Schottel Drives, Azimuth Drives and Voith Schneider drives for a project I am planning. In our world the Azimuth Drives are Schottel Drives mode to look like Azimuth Drives due to the size of the motors. Voith Schneider Drives are a crazy price, so I and still thinking about which way to go and until I can really get back in my workshop thinking is all I can do at the moment.
    Roy, Great explanation of the drive types

    The answers are OK it’s the question that is wrong.
    It should be β€œWhich is not a sea route connecting the Atlantic Ocean to the Pacific Ocean”
    Answer β€œ The Cape Route”

    There are three correct answers, The Straights of Magellan connects the Atlantic to the Pacific.
    It was used long before the Northwest Passage was successfully navigated and even longer that the Panama Canal.

    The Royal Cape One Design was popular yacht in Cape Town as it had a simple construction and was relatively easy to build. It had the nickname of the Flying Coffin due to the shape of the hull and it was built out of plywood. The design would lend itself to a model that would be easy to build.

    Part 2 – Connectors

    Many of you will not agree with me but this is my approach based on years of experience. Connectors are a necessary evil in model boats, so the best approach is to only fit them where it is absolutely necessary. Each connector is a potential point of failure due to vibration, oxidisation and potential dry joints.
    A connector on the battery is necessary as it often needs to be removed for charging, an additional connecter can be used at this point as a battery switch/isolator (see picture)
    Bullet connectors are desirable on brushless motors as they enable you to change rotation easily. Once sailing trials are completed, these connectors can be replaced by permanent joints that are properly sealed or directly wired to the ESC.
    Other connectors I would ask myself if they are really necessary.
    As for terminal blocks of any type, avoid at all costs.
    Without starting another heated debate, I prefer XT range of connectors as they have proved the most reliable connectors I have used. Ripmax and Tamiya I would avoid unless you have no other option.
    I would always attempt to keep my radio equipment in a watertight container and seal all wire access points with silicone and use boots on linkages.

    I will cover another method of sealing wiring in my next article - little known magic.

    The pictures cover the various connecters available as well as inexpensive tooling to hold the connectors while soldering them. This will ensure good joints and avoid burnt fingers.
    The other picture are some of the available moulds to encapsulate the joints on the connectors, when I am able to get back in my workshop I will do a β€œhow to” video of me using my mould.
    I am still not able to work in my workshop at the moment so my apologies for the lack of β€œhow to” pictures.

    RN,
    You are correct, Dias named it Cape of Storms but when he returned to Portugal the king changed this to Cape of Good Hope as it was a route to the spice producers of Asia. After the Dutch East India Company established a re-supply station here the names became interchangeable.
    Another myth is that the Cape Point is the southern tip of Africa, the southern most part of Africa is Cape Aguascalientes which is about 100 miles east of Cape Point.

    My late father used to run a 36” model of Miss Unlimited with a 10cc glow motor. It was clocked at over 50mph and the rooster tail was something to behold.
    Needless to say, it was the only boat in the water when he run it πŸ˜‚
