At the Behest of Greg  ( gondolier88).....here's few photo's

I designed and built it all.













I don't think she holds a candle to "Tarka", but I'm proud of her anyway.

and so you should be, she's beautiful.  You could simply enjoy looking at the installation never mind the pleasure to be gained from actually sailing her.  Fabulous job and you are quite right to be proud of her.

Thanks Bunkerbarge!

Thanks Dave,

A wonderful little launch- looks like she has a turn of speed too- how fast can she go?

Is that a modified Tiny Power M engine or is that your own design too?

I love the hotwell/bucket  , nice touch.

And that oiler on the engine is quite impressive too!

Hi Greg,

Thanks for your kind words.

The boat is 25'  x 5 ' and is loosely based on "Panatella"   All the engineering and construction was by me.

The Engine is a 1.5 x 3.0x 2.5 compound with piston valves that I designed and made patterns for.  I also machined it.

Inside admission on the HP and outside admisssion on the LP.

With 100 psig and no condensor I hit 6.3 mph.     With 160 psig...."significantly faster" I couldn't get a measurement as I was busy with the plant, but my wife screaming at me to slow down as she was getting wet from the spray over the bow with every wave!

The condensor and wet air pump are in process projects....I'll let you know once I get the bugs shaken out....I think 7 or 8 knots is possible

She swings a 16 x 18" prop used just as I found her with rough edges and all.   A good polishing will reduce friction significantly.

That WAS a water can for a flower garden........

The oiler is centralized on off and overall flow.  I have three adjustable feeds from there to the main bearings.   One lever shuts it all off, which is convienent.   The conrod bearings are pressure lubed with a ratchet style pump on the forward side of the engine.  That works wonderfully at 600 rpm...as the probability of drip feed on the rods at that speed is slim to nil.
I run 50w non detergent oil in all of it.   NO internal lubrication...doesn't need it.
2+ HP @ 600+ rpm

The cross heads and eccentrics I handle by hand oiling, though I may add a drip for the cross heads this winter.

PS   Just bought some fishing gear for me and the kids.....should be fun!

Ahh, someone who knows how to put a propellor on a boat- it's a fine hull and coupled to that prop i'm not surprised you get such a good speed.

I would always make sure the crossheads are well lubricated- on stephensons link it gets so noisey with even a small amount of wear.

Good hunting!

..

Box links work well to hold the oil, unlike the usual slotted link, the slots are on the inside and there is two of them for double the bearing area.....

A little squirt right on them and capillary action takes the oil to just where you want it.....
