Progress Again

| 0 komentar |
I now have all the steering system hydraulics fitted.  Flow and return pipes have been run from the steering pump to the ram and with the help of my wife turing the wheel to order the system was filled and bled. Here is the helm pump.  I have removed the wheel again as its sure to get damaged.


I have also fitted the an external 13a socket, the 16a power inlet, 12v switch panel, locker doors and the red bit is the megga loud alarm sounder.

Sam the canopy maker came again today to start the final fit.  This has enabled me to finally get the big tempory cover off.  Whist it has done a stirling job the constant noise of it russtling in the wind has really irritted me. So..........

And the big reveal...........

I have a comment from an email corrispondent about the pram hood:-"The dogs Bollocks"  guess he didnt want to put it in the comments box. I aggree.  I will show it off on another blog later on as to what it does.

While Sam and indeed his daughter Sam were fitting  this I was bust up the front end.  I have removed the horible steel front doors and replaced them with the loverly oak ones I had made.

The grind marks are to remove the hinge

Finally today another delivery of furnature to finish off the kitchen and for the bedroom.  Once again it feels like things are moving again.
Its strange how it goes, you seem to be working and nothing seems to get done, then in a couple of days all the prep comes together in a big way.

Sam is back on Friday to put the final fittings on the cover.

5000 kids with not a turkey in sight, a CEOs Thanksgiving wet dream, a little needful reading, and easily the best description/rundown of the current clown car posse Ive yet come across...

Considering the day, I cant think of a better way to get started by saying thank you for reading Boat Bits, thank you for coming back, and thank all of you who drop me lines with your thoughts, links to neat stuff, and friendly banter. Its appreciated and I know Im lucky to have such a great audience.

Thanks...

Whimbrel Yet Again Two Comments

| 0 komentar |

Robert has followed-up on the previous couple of comments: -
Ross, since you see the utility inherent in the slot-top option and go so far as to state you would thus modify Whimbrel for your own use, would it be feasible to offer an additional sheet in the plans to make this an option?

Then there is that magic number I was waiting to see... the hull weight. I know more than one person is eyeing Whimbrel as a possible Everglades Challenge option. I do hope the actual number is "significantly reduced" as you believe. The Core Sound 20 finishes out at between 500 and 600 pounds sans gear, no cabin of course. Time will tell...

Well, I have to admit that I havent done a full "weights and moments" calculation on Whimbrel. What I did in the previous post (with full disclosure at the time) was to take the total volume of plywood in the boat, multiply the volume by 600 to determine the weight of the ply in kilograms, and then I simply doubled it to account for timber components, glass, epoxy, fasteners, rig etc. This is totally unscientific, but I believed it to be conservative. What is more the selection of 600 kg/cu.m was also conservative, as we are able to obtain good quality marine plywood here which has an actual density of 420 kg/cu.m. The reason that I used 600 kg/cu.m as the figure was to account for the variability in the actual weight density of plywood supplied by the retailers. There is a retailer in this country selling BS1088 plywood which is advertised as being 430kg/cu.m - but when tests were conducted locally on actual samples, the density proved to be around 600 kg/cu.m!!!
If one was sure of having 420kg/cu.m ply, and even using the conservative doubling system that I described, the weight of the boat (including decks and cabin) could be as low as 220kg/484lbs.
Im sure that the Core Sound 20 is an excellent boat, but she is a different vessel from Whimbrel. Firstly, Whimbrel has a full cabin, lots of built-in compartments, a self-draining cockpit, and a tabernacle. In addition, I designed Whimbrel to comply with the scantlings rules as laid down by Dave Gerr N.A. who is currently the Principal of Westlawn. as far as I can make out from my own study and from discussions Ive had with a well credentialed Westlawn graduate, Dave Gerrs scanting rules are conservative in comparison with ABS standards - in other words, if you build to Daves rules, the boat will be stronger and slightly heavier than required. I am very happy with that!
One of the things I had in mind when I drew Whimbrel was that I wanted a solid little ship which would last a lifetime. As you are probably aware, I hold the work of Phil Bolger in very high regard, but I was mildly concerned to discover that a Micro built to specification was somewhat flimsy. For example, you can push the side panels in and out, and when walking around on the cabin top it is necessary to place feet near frames, bulkheads or other supported areas, because the 6mm/1/4" plywood (from which the entire hull is made) flexes alarmingly.

Whimbrel has 12mm/1/2" panels on the bottom, 9mm/3/8" ply on the topsides, 12mm/1/2" on the cockpit floor, cockpit seats and cabin sole, and the cabin top is made of 6mm/1/4" on 50mm x 20mm (2" x 3/4") longitudinal stringers on 200mm spacings or less. This is a rugged "tugboat-tough" boat and not a light-weight daysailer.

Yes, I will do a sheet covering the simple option of a "slot-top". One could easily stand against the forward end of the cabin and reach down into the anchor locker and deck hatch.

I went back over images I have and could access of scows among American watercraft, where they were used in the Gulf of Mexico fishery and for transport of timber, coal and other bulk cargo along the US west coast. I find, contrary to the opinion I expressed earlier regarding Whimbrel, that most or all of them have the bow transom terminating at or near the waterline. They were, of course, coastal and inshore craft, but they still would have met severe conditions at times. However, all of those were much larger vessels than Whimbrel, with displacement in the tens and hundreds of tons, with vastly more inertia in meeting chop or steep waves, able to punch through any but the biggest waves but hopefully able, while plying their trade of coasting, river transport or inshore fishing, to make shelter before such severe conditions arose. Their hullforms, like Whimbrel, were determined by their function, with priority over seakeeping, often for the benefit of operating in shallow water, taking the ground at low tide and carrying large volumes of deck cargo. In a boat the size of Whimbrel I would still find it safer to follow the design habits of one of the peoples with a long tradition of scow bowed small craft, either the Scandinavians, who invariably got their open water round bottomed prams profile and buttock lines well up out of the water before they terminated them in bow boards, or the Asians, who on smaller craft either rolled the bow boards back to a very low angle of attack, like a garvey but much narrower, or built them with narrow stems flaring into transoms well above the waterline, or some of each. Still, I want to make it clear that I admire Rosss Whimbrel design, have since I first saw it, and I understand how the original clients parameters resulted in the outcome. The boat is meant to be used as a camp cruiser, not a passagemaker, so the design is defensible as Ross puts it. That said, Id still make what I consider better use of scarphed whole and half-sheet lengths of marine ply and make its shout a bit longer, thus narrowing and raising it, while keeping all else the same. His rig, accommodation and use of leeboards are a winning combination on such a small craft, and the accommodation and applicability of leeboards are both facilitated by the scow bowed hullform. Its a very neat solution to a nettlesome set of design parameters, which I like a whole hell of a lot better than solutions to similar parameters by some others who shall remain unnamed.

I thank Rick for his comments, and given that I have already responded to his initial comment, and because Rick has written so well in his second piece, I dont feel the need to reply further. However, I hold Ricks opinion in high regard, and I have therefore been moved to continue with hull modelling experiments with longer hulls which carry their transoms higher and less wide. Unfortunately, my time is so limited (it is the old One-Man Band thing again - Im trying to be a boatbuilder, a designer, a blogger, an email respondent, a magazine writer, and a retailer of components all by myself - I just cant get it all done, Im afraid), that the initial modelling attempts need more time devoted to the detail.

Amateur Boatbuilding Coming Alive Again

| 0 komentar |
All things boating have taken a hammering over the past decade, with most people suffering to a greater or lesser extent through the financial woes that flooded the world. Initially, amateur boatbuilding seemed to stay quite strong, while sales of production boats went into a deep slump.

After amateur boatbuilding also started to weaken, it was interesting (but distressing) to observe the progression of the slowing sales around the world. First to go were the industrialised countries, led by USA and UK, then it spread to less developed countries. It is said that when America sneezes the world will catch the cold. When we lived in South Africa we could watch that phenomenon and knew that what was happening financially in USA, whether up or down, was likely to be mimicked in South Africa within a year or two.

The one market that seemed to stay remarkably buoyant was Russia, where amateur boatbuilding seemed to stay strong. Then war and politics stepped in, the Russian economy took a dive and sales of plans to amateurs in Russia also fell.

Boats are not an essential part of life for most people. For some they are transport or a work implement, for others they are a home but for most people their boats are toys, sporting equipment, or somewhere between, certainly not high on the list of essentials when money becomes tight.

Now we seem to be coming out of that slump. The US economy has been showing signs of life for a year or two and that now seems to be filtering down far enough that amateur boatbuilders are again starting new projects. If the normal pattern pertains, the upswing will spread out to the rest of the world as well.

Over the 35 years that I have been designing boats professionally, I have drawn mostly boats that are suitable for amateurs to build. This was not an intentional path in my design career but, in retrospect, was probably the most natural and logical one. My roots are in amateur boatbuilding, when I built a plywood 36ft cruiser/racer in my in-laws garden, based on a design by Ricus van de Stadt. My own first full design was the CW975 for a 32ft plywood racer/cruiser, which I also built after it won a design competition. The third design that I drew was the steel Pratique 35 cruiser for an amateur-builder friend. Next was the Coquette 39 plywood racer/cruiser commission, also for an amateur. Only after that did I receive my first commission from a professional builder for a production GRP boat.
My own 2nd big boat project, the CW975 "Concept Won", in my garden.
This depth of involvement with amateur boatbuilders and designs has resulted in a long string of commissions for amateur builders, mostly for plywood. My own third build big-boat project, in the form of the radius chine plywood Didi 38 "Black Cat", and my well-publicized voyaging in her, have reinforced that trend. For the past 30 years I have always had at least a year of work waiting in  line. That has now expanded to a 2-year backlog and I have had to turn away new commissions to keep the backlog somewhat manageable.

As the slump deepened, the average size of boats that people chose to build slipped lower, until we were selling only dinghies and trailer-sailers. Now that average size is starting to creep upward again, as builders move back into bigger boats. The most durable design that we have is the Argie 15, which has developed a good following that keeps it going strongly through thick and thin.

In trailer-sailers, the little gaffers, in the form of the Cape Cutter 19 and Cape Henry 21, are the ones that keep going. These lapstrake plywood boats are more complicated projects than a simple stitch-&-glue boat but they are just so pretty that they have attracted a good following. They have also proven to be quick in the light stuff and capable in the rough stuff, so they have grown a reputation for being desirable boats. That resulted in the upward expansion of this design range with the Cape May 25.

Newest in this series, and already generating much interest even before completion of the design, is the Cape Charles 32. Although not yet on our website and pricelist, drawings have already gone out to the first two builders. This one is a coastal and offshore cruiser, with shallow fixed keel and external ballast, whereas the smaller sisters have steel centreplates and internal ballast. We should have a web page for this design in a month or two. Until then, please email me for info on plan price etc.

It is not only cruisers that are growing in popularity. One of the commissions that is waiting for attention is a bigger sister to the radius chine plywood Didi 950, at 11.4m (37ft). I have also been asked multiple times to draw a Didi concept to the Class 40 Rule but am not able to fit in the design in a reasonable time, so have turned down the commissions. Meanwhile other larger boats in our radius chine plywood range are also starting in various countries. This includes the first in that series, the Didi 38, with two new builds starting in Asia.

We are also experiencing increased interest in steel cruising designs, which have been very dormant for the past 10 years. Overall, amateur boatbuilding is looking a lot more healthy now than it has for a long time. Now we all need the politicians in all of our countries to play nicely together. If they do that then life should improve for all of us. Lets all go play with our boats.
