Of course it's very important to know what is correct info and not ....and what is opinion and not...

Plenty here have already told me my experience and opinion ain't worth diddly...I think that the same criterion should apply to anyone that can't back up their info with something more than a post...even when I back it up with plenty of substantiating info the few still pile on.

So have at it...believe what you want...heck you won't get a diploma from TF...

....but I'm happy with the real person meets I've had and PMs that keep me going here....so I'll stick around till I feel I've totally lost it.

Xsbank,
I think it's the bow. I've seen them underway and the bow wave is just plain big. And looking at the boat in the pic from dead ahead says that Mark would never call this boat a "slicer". She looks really slick from the side but the bow is to put it bluntly ... blunt. But if enough speed was ever attained to raise the bow she's really move along .... IMO.

But the worst thing I observed was the tiny rudders. Small props, small shafts, small keel and small rudders makes for low drag but low thrust too. A following sea would not be a place to be.

But I love the cross sectional shape and general styling of the boat, especially the bridge from inside and out.

Mark,
Re the rest of the boat the propeller and rudder aren't large. Compared to the boat my rudder on Willy is larger. And the prop is rather small in dia. Some one went looking for blade area though. Must have quite a bit of power.

Yeah! Got another boat like this one?

I thought the prop, being four bladed, had quite a bit of area. I think there's ample rudder too, but Willy is over-endowed in this way, don't you think?

Fugio-Eric- You have me confused which is not a hard challenge. I have reviewed several times the photos and can not locate any draft markings. Which photo is involved?

XsBank- Define "Noodle" please.

As to the social graces of Big Bad Bayliners wakes there are none!

Larry I meant the compliments .. Not the Susan. But I'll see what I can find.

Yea it looks like they were maximizing the blade area. Usually that's for absorbing power where there's not swinging room for more diameter. But here it looks like there is room for a bigger prop. My Willy is the same but not re the blade area. Perhaps the prop on Susan Gael now is not her regular or original prop.

I'll take a picture of the type of prop that I'd think is more appropriate for the Susan Gael and post tonight.

Larry if someone was to steal Willy's rudder I'd want a replacement just like the existing one. Not too much rudder at all IMO. I have Willy's rudder rigged to swing 45 degrees both ways so if I was to change rudder size I'd want slightly bigger. On a 6 knot boat I don't know if there is such a thing as a rudder too big. Being 3/8" thick it's very heavy so a composite rudder may be a good idea. But smaller I'd not want. So no I don't think Willy's over endowed in that regard.

Well, this kind of reminds me of when I have to explain my jokes multiple times and my wife says if I have to explain it then...both of the stern bottom images show the marks. Let me isolate and increase the contrast for you:


So, what's curious about these marks is that they don't appear to accurate scale, and - more on my point - they go UP from XVI to XX, which would indicate that the draft INCREASED as the boat settled. Hence my comment about a possible AIR draft.

Honestly, though, I think they're simply whimsical - and the welder either didn't know or was playing a joke on the owner.

Edit: <forehead slap> Of course the draft increases as the boat settles. Never mind my air draft comment. Still, the markings do not seem true to scale.

rufugio,
Nice flowing lines for an old steel boat. I'm going to take a wild guess and commit that that must be in Seattle.

Here's a prop on another boat in our yard .. a clipper bowed motor sailor. This prop is also a 4 blade but the blades are long and slender. The blade tips are very small and even smaller due to the profile shape at the tip. Skinny and pointy tips are much more efficient than wide tips. The wide tips provides large blade areas but there is many times more opportunity for water near the blade tips to tumble radially off the end of the blades loosing large amounts of thrust.

Airplane wings suffer or gain from the same proportions of their wings. Long and narrow like the wings of sailplanes gives great efficiency.

The lower the gear ratio and the bigger prop produces the greatest thrust .. BUT only at maximum output. The efficiency/rpm curve is rather steep for bigger and slower props and flattish for smaller higher speed props like outboards .. especially small ones. So at cruise speed (many trawlers at 25 to 30% load) a smaller faster prop would most likely be more efficient. But for maximum static thrust larger dia and slower speed is king. This paragraph is open to debate of course.

I agree another oddity to me is how does a vessel of this size only have a 20 gallon holding tank? Considering the sizes of the various fuel and water tanks I would think a much larger holding tank would be in order for when the boat is in marinas or protected waters.
The lower helm windows? Well they really make the vessel an ugly duckling and appear to really limit visibility but hey, that's just my opinion......

Bill111- Three way valve!

SoF- 424 hp claimed divided by 3 gives close to what an older block 671 was rated: 125 hp to 150 hp as I recall.

Refugio-Thanks!! had not thought to magnify the image.

As to this fine "Portholy" craft- It needs slanted forward portholes, and a review of the dinky anchor. Have to love the mid chain sheve. One would wonder if the stabilizers are part of the missing Keystone Pipeline!!

They give 424 hp for the 6-71 and 72hp for each of the silly wing engine arrangement.
