Beneteau 34 Trawler

[KINGFISHER 9]

New ST 35 recently announced.

1000 gallon fuel capacity?!! I think not. But she does look a nice boat, classic lines. But I am rather biased when it comes to trawler yachts.

Is your's an Island Gypsy? I love the Europa style trawlers.


3mpg@6kts
2mpg@8kts
1 mpg @ 10kts
Above 10kts: don't ask...

Do those figures look OK for a 36' 12 ton trawler?

Oh dear. This is what happens when you design a boat without talking to me.
Instead of an upgrade to the ST34, with its niggling problems fixed, they have created a larger ST30.
I like the opening transom but nothing else. Nowhere to store or launch a tender, what a disaster. Will this ruin the ST34 second hand values or make them more desirable? Will Benneteau stop making the ST34? They are still advertising them.
Thanks Kingfisher, I've been waiting a long time to see an upgrade. Now I wish I hadn't

A Defever 48. Our max cruising speed is 8kts, normally 7 - 7.5kts, we work on about 2.5mpg.

Broom: lace curtains and dinettes.

GB: floating club house with wood paneling .

Hmmm...

Dinette yes, but Oceanair Blinds I'll have you know :encouragement:

Thanks.

Those numbers are very acceptable for a heavy trawler.

Brooms are fantastic boats.

Don't forget the daddy of them all: the Grand Banks 36.

It's Max continuous cruise of 16kts on twin 210hp is impressive, and they keep their value well. You're getting 11 tons of solid GRP instead of 8 tons of st34 with the same hp . Remember the st34 can only run at Max speed for 10 minutes in every hour.

I'm interested in the comment of 10mins in every hour. I've tried to find out the situation but drawn a blank. Is this indeed fact and if so is that the norm?

Didn't see the second part of your question.
The American system for rating the duty cycle of marine engines
http://www.impcorporation.com/blog/marine-engine-duty-ratings
The ST34 now has the QSB6.7 (replacing the venerable QSB5.9)
For higher horsepower these engines are turbocharged. The un-turbocharged version of these engines are unstressed and have a much higher duty rating. This is normal and if you want to plane it's necessary to have turbos.
Expert opinion is that the QSB is worthy of a much higher rating but it is marketed for the leisure market

Thanks, I see the 2 hours out of every 8, as far as I can see it doesn't indicate any restrictions at lower usage. I tend to run my current outboard at 80-85% for hours at a time and wondered if that was doable on inboard Diesel engines?

Cummins say as long as it's 200 rpm below its maximum rated rpm is ok.
The 5.9 and 6.7 are not engines that you have to worry about. Give them the love and they will always be there for you.
Piers did a course with Cummins that means he's qualified to service his own engines, I'm hoping to do the same course soon (when my wife says I've got over my shoulder injury).
