And if you go from SD to FD you won't need as much power .. probably about 40% less depending on the design.{Hummmm, Eric, there would be nil addition to water line length with a fan tail addition as the addition would be flared into the hull line as it is now with the bottom of the fan tail unit flare from there would add no more than a foot of water line length as it rose to the exposed remaining construction. I do not believe there would be any noticeable difference in performance outside of the desired yawing reduction in a following sea. That said, the current HP regardless will not add or detract from present performance hence, a smaller 4-154 engine as we had previously, while suitable, was running like a hamster to make the turns where as the larger 4-236 is accomplishing the same outcome at a much reduced and quitter RPM with the same fuel burn. I realize you are infatuated with the application of the lessor HP to achieve hull performance. Nothing wrong with that concept. There are others such as myself that find comfort in having a engine that large enough in the individual's mind to achieve or exceed hull speed for various reasons. in my case a small boat where sharing the engine space with the living space in closer proximity than larger craft, less cabin noise is a quite boat underway. Our db sound level is 7l dbs at 1350-1400 RPM, our average speed fluctuates between 6.5-7.3 knots at 1.5 gallon per hour fuel burn. I am happy. (On the bridge, the dbs are 60 db)

Quote continued:Yup you can leave the rudder and keel as is but having all that mass well aft of the rudder will make for a poor handling boat. If a quartering stern sea is pushing the stern downwind the rudder will be quite ineffective. But there is a commercially built boat that I think that was done to. The Gulfstar looks for all the world like that's what they did. Probably had a ready made mould and then decided to build a bigger boat.


I agree to your response given a extension length that was excessive to the overall. One would or should I'm thinking have professional review of any anticipated lengthening or have personal interaction with a similar existing boat already modified.
That said after conversation with a couple of those gillnet boat owners who seemed satisfied with the outcome.

Thanks for the conversation Eric. Always a bit of enjoyment

Hi Al,
I'm just talk'in theoretical ideal. I usually do.

I was lucky. I had to repower so actually got to research the power requirement and I spent quite a bit of time doing that.
For most it's not worth the effort to repower an old boat just to be ideal. And to others it dosn't even matter. And for others, (like yourself) other things are more important. Many (perhaps most) don't like higher rpm. To me it's totally immaterial. With X amount of w ...... this is not on thread topic. I'm out.

Were you acquainted with Lee Knudson? My dad had a boatbuilder account there from when he was building an Ingrid and it transitioned to me. Lee was a great guy, sad to see him (and the business!) decline.

Sure, knew Lee and Pete, Bob and Norm the mechanic. I even found receipts from Doc Freemans on the boat I bought last spring! I worked at the store a bit while still in HS around 1970. When they moved the store to Ballard it was over, just took a couple years to finish it off. The original store was a great place to pick thru stuff and make offers and find bargains. The whole bldg. has been converted to office space now, all changed. Fremont Boat is still there of course for moorage and Fremont Tugboat, my cousin Erik's company now is there and thriving. Docs son, my Uncle Mark is about 82 now and is still active but not on the boats anymore. He is busy writing books and running the tugboat "museum", building models and having a pretty good time for the most part.

78,
My father moored his 103' boat alongside the Edison Tech boatbuilding school. That was about 1950.
I rode my bicycle from the Ravenna district down to and around the lake when the Gasworks was a refinery.
I sure remember Doc's. Was most often crowded in the store. Wish we had stores like that now.

Eric, we traveled some similar paths for sure. I walked around Lake Union by myself when I was 6 years old. Its about 6 or 8 miles if I recall. I left our houseboat on Fairview E. and stopped at Fremont for cookies with my grandma, and finished the trip in time for dinner. This was of course about 1959, I sure would not let a 6 year old do that now, might not make it home. Times have sure changed. What was your dads boat and the name of it?

That's a nice boat...In early 1990's friend of mine had a similar Chris. His was from early 40's and had been commissioned as govt boat during WWII. I and a couple others helped him redo it's bottom. Fun project, lots of effort.

I don't think the stem has enough rake to it, but be cool if it was. Looks better without the FB in Army mode.

Saw this old beauty (BC Venture - built in 1944) anchored in Eagle Bay, just south of Kitimat yesterday. Don't know if it's still for sale, but it sure looked good from a distance

Dave,
Interesting boat to be sure but not the 37CC. The 37 has a vertical stem.

The CC you posted is really fast and looks to be a WWII boat. I can't read any of the text.

Murray,
The Venture in post #32 looks like a dead ringer for our old TF guy slipperdude. From central Alaska. Seward or somewhere around there.

Otto Candies Offshore donated this mockup of one of their supply vessels
to the bayou Country Children's Museum in Thibodaux. Inside is a lot of the instrumentation as used on a vessel. The large screen runs a video taken from a boat going down Bayou Lafourche at the same time the depth finder radar and other readouts are synced to the scenery. Kids can go in and "drive" the boat. Very nice job and donation, thanks to the Candies.

Know how folks like to say, " the pix don't do it justice"? In this case having seen it up close, the pix are more than fair.
