    Looks like a Seadog 30 motor-sailer.
    Cheers.

    As @gwboats notes, she is a Seadog (re the boat with the blue boot topping).
    @kdifzero is she for sale, and you are potentially interested in her?

    Here is a link to three for sale on Apollo Duck

    Thankyou


    She is not for sale afaik as it is a screenshot from a video uploaded in 2018 by a dinghy cruising youtube channel, caught my eye due to it being a triple keel. All same thank you for the helpful links.

    Cheers

    Many moons (33 years) ago I worked in a small design office in Southampton.
    My boss had a Seadog 30 motor sailer, and I went out on her a couple of times - one time we all went to watch the fireworks at the end of Cowes Week, and we had a nice sail over to Cowes and back. They do sail reasonably well once they have a good F 4-5 to get them going.

    Another time we used the Sea Dog to carry out some very sophisticated model testing of a fast power cat we had designed.
    We used a windsurfer mast as an outrigger to tow the model on the side, in calm water on a quiet afternoon on the River Itchen.
    With fishing line attached to a spring balance to measure resistance.
    And our results were very accurate, when we later compared them with the trial results on the full size vessel. :)

    Edit - I just had a closer look at one of the Sea Dogs for sale (as mentioned in my previous post) - and I see that she is my former boss's boat Tresco Maid.

    Hi bajansailor,

    I thankyou for your lovely trip down memory lane it is no wonder you seemed keen to throw in a few for sale links and what a coincidence one of those is the very same boat.
    I actually really really like the design, but she is a very heavy boat and I do wonder how fast you could get her going with a different rig and much lighter displacement. The shallow draft being a big plus, would be great on the canals.

    Cheers


    Edit: Just checked the one you linked again and its a 6 tonne displacement, the other links had steel as hull material, hence they were 12 plus.

    I think that speed is relative - how fast would you want to go with a motor sailer, typically?
    They are comfortable boats when underway, with an easy motion, and one advantage of having a reasonably powerful engine is that you can then motor sail if you want to keep up an average speed (eg to meet a tidal gate deadline).

    I have not had any experience of the French canals (I presume that you have these in mind?), but I have read that bilge keels are not ideal, as the canals get shallow at the sides, and bilge keelers would probably be more likely to come into contact with the bottom / sides than a slightly deeper single keel.

    I am a bit baffled here - all three of the Sea Dogs in the Apollo Duck link are fibreglass vessels, around 6 tonnes, so where is the reference to steel and 12 tonnes?

    I laughed when you said F4-5 to get her going. My first thought on seeing the pic was that there's going to be some unfortunate turbulent interaction between the keels at speed, and massive surface drag below that speed.

    I understand its a motor sailer first and foremost just wondered what could be achieved with a newer lighter engine and as now corrected below a lighter displacement.

    Yup Euro canals what I had in mind

    I misread the 12 tonnes it would seem from the below link and then as the for sale links showed 6 tonnes just assumed that some might have been steel hence added weight difference. I now gather they were all fb.

    I don't think you would achieve much of a gain speed wise by having a lighter engine - keeping the hull bottom clean would have a much greater effect, especially as she has such a lot of wetted surface area with those triple keels.
    Once you get to the Med via the canals then it should be quite pleasant (in summer) to jump over the side and go snorkelling to clean the bottom - but it would not be much fun doing this in the Solent! :)
    I remember reading in a reputable source that just a layer of slime on the bottom can knock 10% off your speed - add on some weed and shells to those 3 keels, and your speed will drop dramatically.
