    My youtube chanel is wildbillybass. there's other video's and you can hear my 489 sing! Actually maiden voyage. I have the quietest propeller currently in production, 2.68/1 gearbox so 5400 engine rpm prop is swinging 2000 rpm and 3" exhaust with mufflers into single 5" tailpipe. Actually pretty quiet! no problem carrying on a conversation on the bench seat, tougher talking with your butt 6" fron the harmonic balancer! No gators up here, Norhtern Canada. Ice is starting to float down the river!

    Sorry country-mate but Edmonton is not northern Canada.

    I'll give you central Alberta but even that's pushing it my friend.

    Busted.

    Well when it hits 40 below with a 60 kph wind it FEELS pretty northern. You are correct as far as geography however. May somebody throw your dry suit away!:D Lakes and rivers are liquid 6 months a year, ice 6 month a year. Did you use your periscope to spot that little nugget?

    No, I used to live in Calgary.

    Take my dry suit and I'll pee on your foot!

    P.S. Nice ride! How long have you had it? Did you buy or make it?

    Vegematic PWC looks like a death trap to me.

    Yeah air propeller driven boats get wider and wider for a reason I guess. 6' is pretty skinney however with a light engine i'm sure it's doable. 7' wide is normally the starting point with the trend to wide like 8' like mine and you can put a pretty fair weight up high but 4' might be optimistic. They had norrower stuff in the old days but they didn't operate them like PWC. They had circle track racers that were pretty wild and pretty skinney. Composite blades can handle a little water on the tips but just a little bit. flat bottom for sure and a soft chine would be nice further reducing stability on a narrow hull. Hard chine and sliding is fun though! Might need to run a water rudder as well as a little air rudder also to reduce chance of rolling it.

    George, a sweet little exercise - neat solution to a very real need for thinly iced in communities...

    Neat if it works, I just don't see rescue people with all their gear taking on a sopping wet clothed person and still able to get up and out of thin ice with this thing.

    My push lawn mower has a more powerful engine.

    I like the simplicity of the concept, just have doubts about this particular example being up to the task.

    At least as a first step you could get to the victim with a survival suit, buying time. Then the skyhook could do the rest.
