Thread: What about a 28ft Mundoo Express Michael ?

Mik will likely chime in when he notices we're talking about him behind his back. He's not difficult to find or contact. Have you tried his site (http://www.storerboatplans.com/)?

Thanks for the encouragement. I went back again to look all over his website again for a way to contact him, finally I noticed the line that wasnt a heading, but a contact link.

Like the title byline says -

""Lots of Websites look really cool but say nothing. This isn't one of them"
ie. his site could do with a bit of a tidyup )

I have sent him an email, so I hope the idea appeals to him

Howdy ... bad news I am afraid. It was a stillborn project. We did the feasibility to get it through survey but no constructions drawings at all.

One of the former owners of Duckflat put it up on the website despite it not really existing. I've just asked the new owners to take it down.

Happy co-incidence here thought .. PAR has a number of boats that might be suitable - he is a bit of a doyen of light skinny powerboats.

oh no! I thought it was just software developers that advertised "vapourware" !

Here is you chance here PAR - where can we see a 28ft, plywood stitch and glue large capacity, trailerable vessel that can do 20 knots, ok for light coastal conditions ?

(I couldnt find a reference to your website on your profile)

As many here will lament, I still haven't gotten around to a web site. Thanks for the nod Mik.

I have the smallest of a series of riverboats, that happens to be 26' LOD, 22' 9" LWL, 7' beam, displaces 2,188 pounds (light) as a flat bottom displacement hull(*). This hull was also done as a V bottom for semi displacement mode and it's particulars are 26' LOD, 23' 2" LWL, 7' beam, displacing 2,324 pounds.

As you can see, there are many possible variations to the theme. In particular are the sheer line treatments and cabin arrangements. This is the V bottom version (both are basically the same) and the weather decks are self bailing. There is full standing headroom throughout the vessel.

Plans where completed a few years ago, but no boat has be launched to them yet. Life changes have temporarily gotten in the way of the client for the build, though I remember consulting on material purchases a couple of years ago. This was just before the economy took a dump, so I suspect this may play a healthy role too.

She's not as efficient as a couple of my larger designs of this series, but 7' beam is getting cramped for most folks and there's only so much you can do in a 26' length. Currently she's setup for outboard power in a covered well, though it could easily be a bracket mounted arrangement, saving considerable cockpit space. She also has my elliptical transom, which really isn't hard to make and looks fantastic, but could be converted to a conventional, boring flat transom if desired.

The semi displacement mode hull (V bottom) uses a few hydrodynamic tricks to get into the upper teens. Her displacement speed is about 8 MPH and she sips fuel like a bird at 7 MPH (less then 1.5 gallons per hour). Her speed will max out at around 19 MPH, as she runs smack dab into a brick wall of frictional and wave making resistance, which limit her top speed to this point, unless you strap an atomic reactor in her belly. She will cruise along very nicely in the low to mid teens for progressively more fuel use (naturally), but if kept below 15 MPH she's very economical. She only needs a 20 HP outboard to motor to 10 MPH, but if you want to go faster, you have to pay for it. A 50 HP outboard will drive her to 16 MPH.

Her hull is a modest V with twin skegs aft so she can take to a grounding or beach bolt upright (engine up of course). If you'd like further information about the design, study or full plans sets, please contact me through email or IM.

Hmmm...

I like it

My friend Stefan Ekner designed a larger motor boat modeled a bit on historic Vistula's dumpers (steam ships):



http://www.charleston.pl/vistula_img.html

That is considerably larger then desired, not trailerable and certainly not especially efficient. It's almost 5 times the volume of my RYD-23.2. I'd hate to have to pay the fuel bill on that side wheeler.

But she is beautiful

Have you seen Ross Lillistone's Three Brothers? It seems to be a 26ft by 820kg (1804 lbs) loaded displacement powerboat which will do nearly 20 knots with a 30 Hp outboard.

Ply stitch and glue construction.

Thanks Ian , Par and all others for the info. The "Three Brothers" isnt really "sort of livaboard", being quite skinny and still under development. Par's boat is a nice design, but not really designed for any kind of speed with the non-planing hull.

The design I have actually bought, and will build if I cant find a smarter, more mature design is the one at Bateau - the GT Cruiser 27
at Bateau: boat plans for amateurs

It at least has the advantage of being able to have any design topsides - because the designed top is very "plain jane"

I might have to do a hybrid - like the attached illustration.

Easy to build, roomy, trailerable with a turn of performance is the priority.

Thanks for the mention, Ian.

rwatson,
you are correct about Three Brothers being quite skinny, as she is designed to be efficient and smooth-running in a steep chop. You will note that she has an exceptionally fine and concave entry - all developable. However, it remains to be seen whether the bottom panels will take the combination of twist and bend without being laminated from two layers of 6mm instead of the single layer of 12mm specified. Initial modelling indicates that the 12mm will do it, and there is one under construction in America at the moment, so I'll soon find out.

I have to correct you though, about the plans being under development - they are finished and available.

Then you need to amend your website -quote

"Plans are still being developed, and will be available after building of the prototype is complete. This will take some time.... 5 May 2009 - work progressing slowly on plans for publication. Next stage of development will involve the testing of a 1:5 scale model."

in the New projects page.

rwatson,

Yes, correct again - thanks for pointing that out.

If you are interested in some of the performance-calculation data and background for Three Brothers, there is a long entry under the "Latest News" button on the website. I'll try to correct the "New Designs" page today.

Regarding your original request, I suggest that you have a look at the work of both William and John Atkin. In the 700-odd published designs there exist a number which may be of interest to you. Although there are some on the Atkin website, you will find that a search for books from the "Motor Boating's Ideal Series" in the public library system will turn up some real Atkin treasures. The other exceptional source for ideas is the Bolger cartoon series from the late Small Boat Journal.

Ross Lillistone www.baysidewoodenboats.com.au

I find nothing especially interesting about a 5,000 pound, nearly monolithic 27' (or so) hull that needs 90 to 125+ HP for regular full plane mode operation. There's nothing efficient in any regard about this, as most powerboat hulls fall into this category.

If however you are interested in less then 2 gallons per hour fuel use, much more comfort underway (guess what that pram bow will do in a chop) and 1/3 to 1/4 of the HP requirements for the same speed, then I'd be interested in the design.

I'm inclined to agree with Ross in that a study of other 26 to 28 foot powerboats might be helpful and a great place to start is Billy and John Atkins offerings. Unless of course, you don't mind tossing a 20 dollar bill, in the fuel tank, for every half hour of full plane operation.
