Princess 33

[Halcyon Yachts]

I was hoping someone can help?

I will be delivering a Princess 33 from the South Coast to Wales. The new owner of the boat doesn't know her fuel consumption or range. I am told that her cruising speed is between 10 - 15 kts and she has a 100 Gallon tank. She has twin 150 hp Mermaid Engines.

What do we think???

Many thanks,

Pete

With those engines she will do 22 knits flat out , I'd say you will get above 1.5 mpg at around 18 knots.

My dad had one with the mermaid 80s and she cruised at 12/13 knots just in the plane.

The tank was 150 gallons.

Wood agree with VP here on the speed.... she is relatively easy driven (presume V hull and not Y ... if Y, she's over engined), so should do 20 knots + WOT.

Guess owner is gentle with her ..... or out of tune / incorrect propellers.... She should run at 11 - 12 Knot + at about 1500 RPM .... at 1800 she should be up on the plane around 15 - 16... and at about 2000 - 2300 should be in the 17 - 19 knot range...

Assuming in-tune, right props, healthy engines, clean hull and not stupidly laden down .....

Yes - I was assuming just one fuel stop required (probably in Falmouth or Penzance).

Thanks for that...

Unless its changed, Falmouth was always the most expensive fuel you could buy, if there's an alternative then make use of it.

I would brim the tanks at the start, go out and run for around 50 miles at cruising speed, stop and refuel at which point you can then work out what the actual consumption is then work out where you will stop for fuel based on those figures. you should be able to check on the tank size once you are on the boat as it might be stamped on the plate.

+1...... Was thinking the same.

My P33 on outdrives and 2 x 135 hp AQD40A struggled to 17 knots immediately after new coat of A/F and relaunch,that was with 99% of junk removed.
With usual junk aboard and a bit of growth 12 knots was tops on a good day.
Amazingly economical at creepy crawly speeds @ about 2 GPH both engines.
Around 4 GPH average over season.
Max was 8 GPH on dash back from St Kats in crummy weather.

Thank you - that's very useful to know!

I will be taking 40 Gallons of extra fuel in cans; if she has stood for a while then it's very likely the fuel filters will need changing on route. She is an old girl so lots of tools and engine spares just in case...

Hoping your job has shafts.
If a butterfly flapped its wings within 100 (miles not metres) ,my boat would set off in a totally different direction to the one desired.
Auto pilot was the only thing that made long distances tolerable.
