robmill0605...retardment bote.....

[paladin]

I based this on Jay Benfords 14 foot tug, Grivit......I wanted something larger, for long term liveaboard and extremely economical to operate. I also did not want to pay exhorbinate prices for marina living, so I had to be able to clear 14 1/2 feet at the North Beach/Chesapeake back creek bridge, and needed 3 feet or less water to run. The craft comes out at 12.5 foot beam and 25 feet long, stretchable to 27.5 feet...the 30 foot version is a slightly different boat..and was done as an excercise to "what if"....The design shows that hull speed can be achieved with 17 horsepower and a 21 inch prop.....If I wanted to stay coastal u.s. and backwaters a 28 hp engine would suffice, perhaps even out to the islands....I drew the system for a 37 hp in order to add the refrig unit if I so desired, a watermaker which I have in storage and extra electrical power in the form of a 100 amp system. With basic fuel and 6 knots theres an estimated cruising range of 1400 miles, or for shorter range and sitting on the hook for long periods. There is room for more fuel and water.
First..Grivit..Jays boat....Rribbitt would have a slightly proportional lower wheelhouse, slightly higher aft cabin for 6/4" headroom.

So far the forward are has a full sized berth and room for hanging lockers around the head with shower. The shower is the only place designed for pressure water. All other areas are designed for foot operated whale pumps or a fynespray that I had as a spare.
The galley will consist of a single burner below the cabinet top for rare occasions or for use with a dutch oven, otherwise a single sea swing stove will suffice. Below the counter is an insulated box...on two circumnavigations I found that it's possible to keep ice for a few weeks in a well insulated box......the only electrical appliances would be a microwave oven and a coffee pot using an inverter....all lighting to be LED's.....for interior and navigation. I have designed the pc boards to retrofit most of the normal fixtures and have an amateur radio supply house making the basic boards. The wheelhouse is 5.5 feet front to back with the forward windows extending on top of the forward cabin, making for a nice chart space....the two seats in the wheelhouse are open below in the aft cabin as a desk etc on one side and a partion wet locker above on the steering side, and below a space for the microwave and coffee machine. The countertop is on one side and a settee on the other, which can be made into a double berth.....storage below the sole and behind the settees.......

Nice one Chuck... mate Ive been wondering about these small tug things and part of that is can they be used to actually tow other boats in need? in other words do they have the solidity and power to do so with safety to both vessels

No Im not suggesting something this small tow a 50ft barge or a 100ft yacht but could they forseeably tow something 10ft or more larger and therefore heavier in displacement than themselves?... In otherwords cn they be workboats as well as "showboats" (for lack of a better word)

But can they be adapted to do so? what spacial area would be needed for storage of large long towing ropes and such?

We've been hearing about this one for a while. I like the lines; she'll look better stretched as Rribbitt is shown.

I should note that she's a few feet too long for my workshop. Geez, Chuck.

[paladin]

what you're asking, Shane...is referred to as Bollard Pull...The ability to tow something else.....of course, but we are talking about a different animal. Knock off the rear cabin, install some extra bracing and the tow hardware, and beef the engine to 75-125 horsepower with the change in prop and tow almost anything comensurate with her size, she is a true displacement hull. You can make the aft cabin shorter and do the same thing and retain a head and bunks forward and a very small galley....and a bow thruster if you are so inclined. I just wanted a very comfortable little cruiser....with dancing girls...hot and cold running maids.......air conditioning....and hot showers in me old age....

[Wild Dingo]

No worries Chuck was just wondering... after looking over Godzilla and this one if it was possible and how what one would have to do to achieve it... thasallmatey! :cool:

Dancing girls?? :D :D :D Well Id be in that like a shot if the missus wasnt around to object as she tends to when dancing girls and me are involved :rolleyes: sheilas eh? no sence of adventure or fun them critters :D

[Robmill0605]

Thanks Chuck,I really like these tug designs.
More!

[JimD]

Cold molded?

[paladin]

could be cold moulded...I have scantlings worked up for moulding with plywood, veneers, strip planked with veneers and fiberglass.....if I build her it will be strip planked with 2 1/8th inch veneers over....and another forumite mentioned carvel which is do-able...

[JimD]

Chuck, it looks by the drawing that you aren't leaving much room for a cockpit. Not even for a couple lawn chairs. But I suppose on a boat this size their isn't room for both a cockpit and servants' quarters?;)

[paladin]

there's 3 1/2 feetz on the after deck.....more if it's stretched....enough room for a pair of folding chairs.....

[JimD]

Any reason besides aesthetic preference you went for a transom rather than a fantail stern? I've always liked Jay's 20'er, which oddly enough (to me, anyway) morphed out of a catboat design:

Thailand - Jay Benford proven design and - Ferro! - it all seems to fit together. Probably lasts much longer, 1/4 cost to build (albeit with a lower resale rate).

Sorry, just my opinion creeping out. :o - only 50 different building yards to choose from, - or was that in Sri lanka?

Ok, I give up trying to post a picture. I've tried the little yellow window etc.What is the problem? ( yeah, i know it's me) anyone?

[paladin]

It's MY DARN boat and I happen to like the transom stern...it's easier to build......and I started it with the idea of strip and veneer....I sent it to Raoul and he said it would be easier for him to cold mold with 4mm marine ply (did scantlings again.....) and in the middle of it all someone at the Concordia yard in Chomburi said he would like one but would do it in one off glass......and another forumite opened his yap about carvel.......so..........with all the crap I got loaded into 4 hard drives it's a matter of a few numbers.....voila!....multinational fabrications......now all I need is someone to say aluminum or steel and IT AIN'T AGONNA HAPEN!:D

[Uncle Duke]

now all I need is someone to say aluminum or steel and ......
Dang, Chuck. You're hurting me here.
I really want one about 3.14156 feet longer, but with shallower draft, stitch and glue below the chine, but carvel above. Bio-diesel generator and solar panels regenerating a limitless battery bank. Variable draft depending on astrological trends. Oh, and I want to build it for less than 10,000 kroners.
Can't you do this? :D:D:D:D:D

[MTRiverDrifter]

She is really nice. Since the free advice is pouring in, I'll give mine. I know the stern isn't authentic tug boat, but I like it. I think making the bow a little less than plumb would improve the looks, though. I'd be tempted to try to experiment with the Cutt's method and have a strong, water-tight hull that didn't need fiberglass sheathing.

Thanks, Good luck

[paladin]

The Cutt's method is essentially a double planked boat with staggerd plank seams and epoxy sealer between planks. Additionally the kevlar cord attempts to hold the planks together and the unsealed planks are trying to expand against the sealer.....it's like using waterproof glue on plywood, building a boat of plywood, and not sealing the surface veneers....
Many years ago I discussed the pro's and con's of the system with Ed Cutts.....his system is like the construction of Viking longboats substituting a rigid cord for a shrinking cord. The kevlar in his system is held in place by epoxy and the cord is like steel, neither expanding or contracting.
In a Viking longboat the planks are held together in a similar fashion using vegetable fiber. The cord is pulled as tight as possible against the planks, and when wet, the planks expand and the vegetable cord shrinks.

I guess its your time in the barrell, feller,:p :p I said it before and I will say it hearrrr too. When others are willing to provide monetary support to your projects, I bet that some imput will be considered at that time, considered that is, right?. Now who is willing to be the first one in line??;) :D :D :cool:

[paladin]

I got's it figgered to clear all the bridges.....the radio antennas will drop aft when one release pin is removed, and put back the same way.....3 1/2 feet is not beachable...but who cares..I can stand up in that much water and it will hit my belly button....the top of the wheelhouse will hold 8 two hundred watt solar panels to charge 4 size 8D batteries plus a starting battery....I could run an air conditioner on one of the inverters for two days with that...plus the coffee pot, slow cooker and microwave oven.......or just put 8 cd's in the machine and listen to moooosic, make some iced tea or come to Mikes part of the world and catch a catfish or two.....you DO have catfish, do you not?:D

[JimD]

Solar power, that sounds nice. Is a wind turbine worth considering? I ask because I do not know...

[paladin]

and as I sit here pondering my navel and the lint fuzz.......I have received samples of some african mahogany speed strip in 3/8ths inch and 3/4 inch thicknesses.....now this stuff will make a nice curved hull and a couple of layers of xynole on top, or a couple of veneers on top and then the 2 layers of xynole epoxy.
I would be tempted to use this stuff over the cabin frames, then a layer of 1/4 inch marine ply with two layers of xynole epoxy......120-160 gallons of fuel, 160 gallons of water....a couple of folding chairs...a couple of bicycles, scuba gear, ham radio, satellite radio,small outboard, dink, inflatable dink......sell the baby blake get wunna the new composting "Airheads" I think they are called......cherry limeade dispenser, extra lime...key lime pie....

[paladin]

I wouldn't consider a wind generator, although under some conditions it might generate sufficient needs, The engine must be run periodically so can generate power and the watermaker and icemaker,

I like to read a motivated man about town, wishing to build a controversial boat, a true man after my own heart.:D As far as fish of any kind, I guaronteaassss you a jerk on the end of the line , like no other fishing guide I know of, too. :D

[JimD]

We need to have a forum poll on what colour to paint it.

[paladin]

Damn, Jim...with a name like Rribbitt what colors are there?.....:D
