    Yes, I think.

    It is my profession, besides bee keeping and farming.

    I would be happy to work with you on a concept. I will have to charge for a completed finished design, though.

    When BlueBell asked if I'd be interested, I started looking into a little of the sea sled history and I feel a 1920s Art Deco look would be cool.

    Sorry Will, my mistake. I didn't realize you earned a living as an artist.
    I was just looking for ideas that might relieve the flatness of John's two slabs.

    Keep in mind John, you don't have to do the same design on each side.
    One will never see both sides at once. Fun.

    I'm happy to give you ideas and a quick concept sketch. Just give me some idea of what you'd like.

    I was just reading about Harriet Frishmuth, and the hood ornaments she sculpted in the 1920s.
    [​IMG] and thought something like an art deco design, in keeping with the design era of the sea sled, would be super peachy keen.

    I carry heavy objects. Anne decides. I will get her into the convo. Small budget though.

    I am considering going down a prop size for a long trip in Serenity to the boatyard. Still getting fairly regular overheats, so the trip to the yard. Anyway, my logic is smaller prop turns at higher rpm for the same power demand. More water flow through the pump.

    No problem. I'm here if you want to discuss it further.

    If the engine is running below the rated RPM, it is overloaded will run hotter. The water flow will be lower too, which compounds the problem.

    Yeah. That's what I figured. Thanks.

    The nominal wot consumption is ~88 l/h, and your 43 liters correspond well with propeller power at 3900 rpm, which tells us you have been running at about 50 % power. That's not too bad for the speed and the bottom condition during the trip, and we still don't know her displacement......
