Has anyone had experience with the Greenline 33?

I'm interested in its hull, specifically the shallow draft, the semi tunnel protected prop, and the rigid fins placed well aft.

Shallow draft appeals to me for sneaking into thin water, tunnel props don't make the stern squat as low (or the bow rise so high) when extra power is applied, and those fins are the only ones I've seen placed so far aft.

The smallest engine seems to be 170hp, which seems kind of big...not much room in the engine 'compartment' and having a 50hp or 60hp option would make it easier to work on and extend the range significantly, or free up more diesel for heating in cold climates, etc.

My ballpark guess is that a 60hp engine would get a gallon or less per hour at 7 knots and be able to cruise easily at 10 knots. That's plenty fast enough for me.

Hi,

I sea trial this boat about 2 hours when boat come market, here is the smallest diesel VW 75 Hp diesel and about 7kN speed and fuel consuptions is gal/7.6 nm.

I think boat is build OK but it is not heavy build, the boat full of interesting and nice solutions inerior.

the boat of seaworthiness is CE-B. Experimenting with sea trial was only about 3 feet waves, so my experience is slim.

CE-B class craft survive theoretically signifying an average wave of 13 feet and bigest wave is 26 feet, but i thin it is not good idea...

NBs

Greenline do like to do things differently. To what end I`m not sure.
However, the 2 engines driving the electric motors on the 40 are 150bhp VW engines. Not sure that helps,but Greenline does/did have access to lower power engines.
Why not just run the engine at lower speed for lower output?

Interesting ( for me at least ) the way the have the beds in the forward cabin. They pivot so they can be 2 signles in v-berth fashion, or swung together for an island berth. That's really clever.
 
Thanks for the information and links :thumb:

Nice to know 75hp is an option. Fuel stops are few and far between where we live and there is much to explore off the well beaten path of the Inside Passage.
 
No sea trial, but have been on a couple Greenlines at the dock. As noted, they are lighter build boats, which is common for the newer express cruisers and similar class boats.

Conceptually, range is where the Seapiper shines. But so does your Sundowner with an extra 50 gallon or so tote onboard. Don't Klemtu and Hartley Bay provide the fuel stops you need?

The PO of our boat put in an extra 40 gallon tank, so we are able to wander a bit.

Last summer we went from Kitimat to Pruth Bay on Calvert Island, then went back up to Shearwater before refuelling. On our way north from Shearwater we hugged the mainland shore exploring inlets (except for Gardner) missing both Klemtu and Hartley Bay, but got home with a good reserve.

I like the Seapiper, but my co-captain doesn't feel the same way.

I know this is tangential (euphemism for drift):blush: but why do Greenline turn a pair of VW diesels into electricity producers for electric motors rather than just turn shafts with them? I suppose it`s to power the electric system when the built in solar panels can`t, but if you are going to put 300hp of diesel in a lightish 40ft SD boat, isn`t that enough? Are they just saluting electric power for the sake of being Green(line)?

Dude!

We're discussing the non-hybrid version here and the 33 is a single engine boat :oldman:

That`s why I said it was drift. Oh well,I figured there would be interest in renewable energy in a Greenline context, but there`s not. Hope you, or Greenline,find a more appropriate conventional engine,170 hp seems way too much.

You can run on the diesels or on the electrics. However, it is mostly a diesel boat. The electrics will only take you 20 miles.

Not sure what the advantage to a hybrid drive in a boat is. In a car you can use the electrics for surge demand and still get reasonable performance from a smaller engine. Trawler type boats cruise at a constant speed and don't really need surge power.
 
Seems it’s biggest claimed advantage is electrical power management. Solar for bright sunny days, engine for propulsive power and battery top up when less sunny or night electric draw. Not really meant to be electrically powered except for maneuvering in harbors at max speed of 4 knots. I like the idea of electrical maneuvering power due to infinite propeller rpm range from 1 to max. Regular diesel with gearbox of 2:1 ratio gives minimum prop rpm of 400 at engine idle.

Twenty miles is good for many get home situations. A get home engine probably far cheaper.
 
Bump...

It's claimed the Greenline 33's fixed stabilizer fins are "break away and easily replaced"...does anyone know how they are fixed to the hull?

Some type of epoxy. There is a recess in the hull where the fins fit in, sort of like plugging them into a socket. I know somebody who knocked one off going at speed, not realizing he was in shallow water. Fin floated, so it could be retrieved...and eventually re-installed.

Ahhh...thanks!

I read somewhere that they could support the boat while grounded (intentionally) so a pocket/socket/indentation makes sense.

You are correct! I asked that question many years ago when I was on the telephone with the factory (after-sales support). I was told that the fins can support the boat in the case of "intentional grounding". They did point out, however, that one must be certain of the bottom conditions before attempting this (i.e. confirm it's something FLAT and hard-ish). Anything else could pose a risk to prop/shaft/rudder.


I have not actually tried this myself, but knowledge that it's possible has given me confidence to try some tightly-timed passages over mud-flats in tidal waters that I otherwise would not have tried.

7kn in a GL33 @ 1gal/hr is not a realistic figure regardless of engine output, IMO. In my boat with the 165 TDi VW diesel with a relatively small displacement of 2.5L, 7kn burns 1.6 gal/hr. @ 2000 RPM (2:1 reduction) - well up in it's torque curve. A similar weight sailboat might, as the GL is dragging an 11' wide submersed transom with much turbulance at that speed, as all trawler types do. She does burn only 1 gal/hr @ 6kn, 1600 RPM. Still, at 7kn the range on the 132 gal. tank with 10% reserve, is about 540nm, falling to about 360nm @ 8kn/2.6 gph. 10kn burns about 4.75 gph. and over half the 165hp engine's max consumption of about 8.5 gph. So don't think 60 HP would get you near 10kn.


My max speed is about 13.5kn @3850 RPM - won't quite get to the VW's 4000 RPM peak - so maybe 155HP.
