Noyo Trawler by Glen L

[Marco1]

Can I ask for opinions on this boat design please?
Particularly interested in difficulty and time employed to build.

I'll have to modify the work boat version to something like this


Purpose is mainly river pleasure navigation, with occasional trips out to sea.
The boat will live among this waters on the Hawkesbury River, Sydney Australia.

I would strongly recommend the DE 23
good plans
relatively easy to build
excellent online support and well supported forum

the quoted 250 hours seems little - but 400 is completely possible

[Kaluvic]

Don't know much about it but my first impression is poor visibility for gunk holing.

That boat look really nice. My only observation is that it seems smaller and it is a planing hull requiring a bigger engine. I was thinking more in a displacement hull. For speed I have a seadoo 180 to pull the girls on the ski. I happen to have a Kubota V1505 35HP with 2:1 gearbox I purchased new to put in an old Halvo, but the purchase of the Halvo fell through so I now have a new engine and would like to build a boat around it.
I initially found this boat but it is a much bigger project and requires a much larger engine. I also have to watch the draft since at low tide I have a few sand banks on the way to my house.

Hi Manie...that webite ha a lot of very nice plans...
What about this one? Would it be hard to build? They sell the playwood precut. Whohoo no cutting!

Not that I want to speak for Manie, just my 2C.

The 28ft trawler is a nice and proven design. (btw at least one was built in Turkey)
It looks like it would fit your requirements almost perfect.
But I doubt they send the precut ply to OZ!? And if, what would it cost? I have seen (no mainly heard about) homebuilts were the people imported Western Red Cedar to Asia, just because the scantlings were based on that.
I think it will be better to ask for a cutting plan sent to your local mill. (they will probably not send it to a homebuilder)

I agree with Richard and i also doubt if a kit would be economical

also remember that lofting and cutting plywood panels for a hull is a very small percentage of the overall build

I like the trawler but at 56 sheets of plywood and 39 gallons of epoxy it is one hell of a lot bigger and more expensive than the DE23 at 36 sheets and 26 gallons
please believe me it is double the boat at double the price and double the headaches
dont build a boat around an engine in your garage

fisrtly indentify your minimum requirements - dont go overboard else it will never happen
The DE23 with a Honda 50 four stroke is a gem and very light on fuel for this application

the guys around here know me and they also know what i am going to say next
start small
build something like this first
http://www.bateau.com/studyplans/V10_study.htm?prod=V10

a small dinghy is a fun way to start
you learn to work with the materials (epoxy etc)
you start collecting and endless stream of tools and clamps
you sort out your workspace
you sort out your life - this is a very serious matter - boat building could lead to divorce
and then you will know if you are truly a boat builder and your family accepts this "new" dad

as you probably realise i am on my fifth build, building my "dream" boat which is a microcruiser at five metres = 16 foot long
the first boat i was going to build when i was in the same place as you are now, would have been an Easy catamaran at 40 feet
shows you how my little chigger and portoguese dory changed my attitude

sure dream big BUT start small - at least you end up with a boat
not a yard full of eyesore junk that takes 12 years to finish

enjoy

I don't like Glen-L designs because they are very boxy. The visibility in that steering station is very poor and not to standards.

Yes Manie, but there is a hughe advantage of these kits. The builder can see a boatshape result in no time! That does encourage quite a bit.

I agree, that, if this is the first boat ever, one should do a dinghi or canoe first.

Building a vessel around a engine is a method I have choosen too. On another scale though.
But I think when puttering around at moderate speed in moderate conditions is the goal, and so I understand it, the existing engine will do a proper job.

Concur. The picture above shows a very poor layout. But the Helmsman can at least see the oncoming weather.

gonzo i agree

I don't like Glen-L designs

they are old and sometimes a bit tired
as we discussed here

Building Methods

for many new builders it often makes more sense to build in epoxy and marine ply with a hard chine design
we have all proved it over and over that a multi chine design is perfectly good for a cruising boat AND easy to build, resistance values are marginally higher so fuel consumption is as good as it gets
those old designs are good for "traditional" builders that want to recapture the romance of a forgotten era
if you want to get to the water quickly go new
epoxy and ply is the invention of the millennium

[rasorinc]

Have you looked at the customers photos on the Glen=L site? Lots of people have built that boat and plans are great and an easy build. Their forum is great also and you will get lots of help.

its a big project

[Marco1]

Hi guys, and thank you for the many replies. I realise that the difference between the DE23 and the TW28 is more than just 5 foot. I am glad to hear that it is a good choice for my requirements and will make sure I got the space and time to pull it off before I start.

I did consider builidng a smaller boat like the Simon skiff 18 or similar but find it hard to find the motivation to build something I don't need. I am a carpenter, (even when in a previous life I was first a blacksmith and then a diesel mechanic) and have built large two story buildings, down to small furniture, doors and windows, shutters and even spiral staircases complete with the laminated handrail just for fun. Still...a boat is a different challenge, particulalry because of the resin/glass component even when stitch and glue is supposed to be easier than more traditional methods.

I had a go at applying a few lyers of glass and poliester resin to an old Chris-Craft, and remember it was not as easy as 1,2,3. Probably can take a course at the local trade college before I get started.

I see the major challenge being space and neighbours since the only place I could build it and take away cheaply is on my front lawn. Will have to build a temporary shelter though, ugly and intrusive.
I could of course convince my wife it is better to use the backyard, but it would require a crane to lift it out over the house and that is probably not cheap even when not impossible. Most backyard glass pools are delivered that way.
Third option is to build it at my weekender, plenty of room and have my own slipway, however it will severely cut down the time dedicated to build, to a day or two a week.

I will have to make enquiries as to the cost of importing plywood precut, and the local plywood cut by miself or third party. I am familiar with importing from the US and have done so many times over. A packet of plywood is not a problem and it is cheap to ship. Probably only hassle will be phytosanitary treatment. Resin is a different proposition. I have never imported hazardous chemicals and would need to ask my agent. Plenty of epoxy available locally, probably not as cheap as yours though. Everything in Australia, besides Kangaroo meat is dearer due to the small population/market... or so they want us to believe.

Will keep on working on this project. I know now that GlenL is out. Let's see what I get started with.

One last question. How would the DE23 perform with a Kubota V1505?
http://www.kubotaengine.com/products/05/v1505_e3_2.html

[Manie B]

The Kubota are good motors, i am in plant hire and work with small engines all frikken day.

keep in mind that you would gear and prop the engine to give WOT approx 90% of recommended rpm to prevent over revving
You would probably normally cruise at 2200 rpm which usually translates to relatively good fuel consumption for the V1505-E3B

Maximum Speed rpm 3000
Output:
Gross Intermittent kW 26.2
hp 35.1
ps 35.6

this could mean that after losses of gearing / shafts etc. you could end up with as little as 25 hp WOT - which is little

sure its a good motor, but the controls and "gearing" forward, neutral, reverse is expensive
prop shaft and seals / stuffing boxes, are not cheap anywhere
vibration free mounting and cooling and exhaust is a major headache
the 40A alternator is nice but the bellhousing to connect motor to gear box is also expensive

do your homework of costs in your area
and then compare to a Honda 50 four stroke
my bet is that the outboard will be much cheaper and easier, even in your country

the kubota will be "fun" for a while
but the NVH will get to you and the underpower is deffinately not nice

the Hondas are very quiet and smooth and sip fuel by comparison
