Low displacement coastal cruiser around 40' / 12M

The October/November issue of Professional Boatbuilder magazine has an extensive article about a new 34' Nigel Irens designed LDL day boat which does 15 knots with a 38 HP inboard Diesel. A sidebar to the article mentions that Irens is "currently developing a series of designs based on his open launch Greta’s 26.5' (8.08m) plywood lapstrake hull optimized for production building in wood. These boats would offer
variations including side decks, a long spray hood, and diesel, electric, or outboard propulsion. The family of LDL launches would be geared to sailboat owners looking for a powerboat, or to anyone interested in efficiency and practical marine electrical propulsion."
Greta was Iren's original 26' open launch.

Issue 145 has an article by Irens in which he discusses his low resistance design philosophy.

Thanks DC,
This kind of where I was headed and great info inthe link, kind of stopped reading PBB once the free paper versions stopped arriving- should probably invest in the subscription as the E versions just get lost in the daily flood.
The Rangeboat 12M seems the closest fit in the LDL style. Design details seem skant which is understandable. I'm wondering what kind of stability enhancements might be added for passagemaking?
They do seem quite yacht like in form, i'm liking the wide shallow stern sections as could be offering a nice space.


Jeff,
 
I think the sor needs work. I don't see you spending a month on the Palm Beach 38. Don't get me wrong. That thing is friggin sexy. But it doesn't look like something I want to spend a month on. The cabin berth is down under and no fly so you'll feel undersea a lot.

I also don't want to spend a month rolling side to side. The Masters 34 Flybridge has all the looks of a boat that rolls all day and even at night when you get up to take a leak. If it planes; it is bound to be pretty flat aft and do what the sea wishes.

The cat does not roll, but damned expensive to slip. Sometimes they make you get a double, othertimes extra footage.

But I'd try to find something with reputable seakeeping.

Facebook group trawler living and cruising has a lot of folks buying trawlers that seem well suited.

Thanks Fallguy,
Agree on the SOR from first principles perspective & also from a commercial perspective. This is as stated just in the brain fart stage but in a perfect well funded world would just see a new build 0f 42/43 foot that would just rage on into the future... but still tough out there.
The Palm beach & Masters would be compromises, the PB are still exxy as second hand and a bit over the top, The Masters dated but closeish without the flybridge as I really want to restrict the air draft to access some local waters.

At present I have a Seawind 24 & a Carter 33 yacht, both great boats but both lacking a feeling of space, one is super low draft & the other close to 6'. the masts seem to be getting in the way these days;) so focusing on economical power, as from a sailing background seem to have a psychological aversion to burning fuel by the tonne(at least when it's my $$).

The SOR could read
Max 42'
Light- mid tech foam sandwich "yacht" construction= like H80/120 + foam & stitched fabrics open to gelcoat - maybe around 8-10 kg per M2 on average, could be solid to CL for grounding at the beach
Floating single/split level apartment that has lots of shade but doesn't look like a barge or pontoon boat. More classic profile.
Low power twin 9.9(inshore only) to twin 90 or single whatever OB- inside engine box a disadvantage.
Swim/boarding platform integrated with OB pod/extension.
Stateroom forward with an island easy to make bed- other "visitor" berths to be settee or similar- think kids sleepovers .
This is mainly an inshore boat but with coastal passagemaking capability thinking around 10 hour port to port at cruising 8-10 knots- most of NSW and Queensland coast this would be fine with no hurry and passages planned in ok weather windows, same way I sail & have always been prepared to motor sail for this purpose.
Some solar generation to support simple electrics, maybe a small compact generator to a purpose built well ventilated locker.
Maybe desal, maybe water ballast(fresh).
Suited to day evening entertaining- stackable chairs & folding/fold up tables. BBQ plus stove with oven.
That should be a start

Thanks for the link bajansailor, similar but my outboard hp range I was thinking on might be as low as twin 9.9 four strokes say 5-6 knots to potentially twin 90/100s & 10 or low teens . looking for quiet river cruising and or some reliable coastal passagemaking at 9-10.
The Halvos are fairly traditional, my wish is for the trad look including an awning covered cockpit- the entertaining back patio/alfresco area..View attachment 162578
The Axopars just a comparitive, with ob power at a similar length though the headrooms low in accommodation areas- the Axos wouldn't look wrong with a 50cal on the front!
The Irens Range seems closest at this point though there's not much real info on them Rangeboat - Nigel Irens Design https://nigelirens.com/boats/power-boats/rangeboat/
The Molly May cool but big and exxy - styling is about right 63' Nigel Irens Modern Classic, MOLLY BAN OF DUBLIN - Berthon International https://www.berthoninternational.com/yacht-sales-brokerage/yachts-for-sale/63-nigel-irens-modern-classic-molly-ban-dublin/ as is the fit out though I'de be aiming a little more austere.
Construction wise I'm thinking 80s/90s race yacht, no exotics just foam & E glass & aiming at about 3 tonne dry, if something as built comes up that might be close enough in the sailing yacht market, got an eye for this as a start point even something like https://www.boatsales.com.au/boats/details/2015-adams-45/SSE-AD-3331213/?Cr=2 this though these are cheapish secondhand.
Palm Beach 38 is closish too View attachment 162579

a man of your skills could surely find a halvorsen at the right price and restore it. you would be saving aus history and getting the boat you want.
 
there are a couple of 38ft halvorsens down here which i think may have been built as raaf crash tenders, a bit narrower beam than most that length but easily driven and seaworthy from what i have been told.

a friend of mine owns masters 34 number 1. it is a great boat. very stable but definately doesn't plane, does 10 knts with a 210 hp cummins v8.

Hi Brendan,
Well that is a possibility, but thin on the ground especially when you start looking. This is definitely on my list of options & a 'safe" one though every genuine refit will often take more than new as needs pull the old apart then put back together.
To a degree ego driven also, I've worked in traditional timber rebuilds quite often & the "glory" always remains with the original builder.. which is fine... Old boats, their builders and the history deserve respect, I'm leaning more towards modern & tough such that it can be beached to load & unload from favourite calm beaches & the systems kind of self contained & simple. One of the builds chronicled on this forum was by Groper- with a 10 metre powercat quite quick & ticks some boxes but cats are convoluted & air draft gets up there- one of the rivers I love is the Woronora, a short but lovely stretch close to home & Family- couple of low bridges & plenty of thin patches- can work the tides but would like the envelope as open as possible there- similar with Port Hacking, lots of great spots in thin water like a lot of coastal estuaries the cool spots don't quite suit the average though the dinghy will often get to these.

great reply jeff. i look forward to seeing what you end up doing.

They are a bit on the tubby side & that's quite a bit of power.
One of the current inspirations is this but hoping for lighter, a little more austere & outboard powered to free up the interior layout... Used Range Boat 39 Day Boat Power Boat For Sale | Boat Ref 36066 | Ancasta https://ancasta.com/boats-for-sale/used/power/range-boat/39-day-boat/36066/

Great links DC,

Quite enjoyed reading some of Ruel's other exploits as well. The linked boat very close in specs, thinking a little more beam & the wheelhouse cabin styling not quite on the money for me but pretty all the same.
I "found" a few of Sam Devlin boats trending the right way for my current thinking:
Bit small & styling more riverboat- Pamlico 32 https://devlinboat.com/pamlico-32/
Getting up in length.. Blue Fin 48 https://devlinboat.com/blue-fin-48/
& bigger/too big, the fuel figures look pretty sweet to 9/10 knots but assuming flat water running Blue Fin 48 https://devlinboat.com/blue-fin-48/
The latter two much more than I'm looking for but cool all the same as is the vids on this link Blue Fin 54 ‘Lucky Star’ – Built in Russia https://devlinboat.com/blue-fin-54-lucky-star-built-in-russia/

Jeff.
 
Just checking some boats out.. via sales ads..

Kind of like this feature, see it on some Dufour yachts also.. not that it necessarily works with outboards..

The boat in the photo you attached looks very nice - do you have a link to her for more info please?
