Paragon Gearboxes
Most Banjers mount Paragon 25L with Perkins 4236 and Paragon 35L with Perkins 6354. Reductions 3:1 both cases.
We thought Paragon Transmissions were not anymore in production, but Doug Frank, General Manager of Great Lakes Powers , the Original Equipment Manufacturer for the Paragon Marine Transmission, formerly The Paragon Gear Works of Tauton, Massachusetts, tells us: "We still continue to manufacture product for the Paragon units. We can still provide a complete unit depending on the model. We can provide for most units complete seal and gasket kits as well as clutch plates, bearings, brake bands, etc."

You should adjust the pitch of your propeller to suit new gearbox.
Consult a reputable mechanical engineer and a propellers expert,
before attempting a transmission gear change over.
26.02.05
Our fellowmember Dees contacted PARAGON's headquarters in USA and asked them the question of letting or not your propeller to freewheel (As to avoid gear damage). Here the answer from Charles Rother of Great Lakes Power Products:
"IT DOES NOT DAMAGE THE TRANSMISSION TO HAVE THE PROPELLER FREEWHEEL. JUST AS
A PRECAUTION, AND YOU PROBABLY DO THIS ANYWAY, THE TRANSMISSION SHOULD BE SHIFTED
INTO NEUTRAL BEFORE THE ENGINE IS SHUT DOWN".
27.07.05 Paragon Engineering, from Great Lakes Power Products inform us:
"The Paragon P25L has tapered roller bearings at the output shaft to accept propeller thrust. The maximum gasoline pleasure craft rating of the P25L is 220 HP at 4000 RPM. The output bearings were selected to handle the propeller thrust produced by this maximum application. The thrust produced by this Banjer 37 application can be adequately handled by the tapered roller bearings in the Paragon P25L transmission".
So, folks which's Banjer mounts this gearbox (And most probably the Paragon 35 also): The shaft bearing located at the rear bulkhead of your Banjers is of no use, and you'd better remove it, in my humble opinion, because can cause alignation, vibrations and heating problems in the shaft.
Guillermo.

PANDORA inform us from Cyprus about the GEBO manufacturer: They are also still at work.
International Steel Supplies Inc. is the original firm, at 's-Hertogenbosch, NL, where most of the stainless steel parts of Banjers were made. They are still at work but seem to be oriented nowadays towards industrial markets, rather than boating.
Banjers mounted a Blake-Lavac-Taylors paraffin cooker with oven and many even mounted also Taylors paraffin heaters. Here you have their home.
The original compass for Banjers was a Silva, made in Sweden. They are still leading you into your proper course...
Banjers Fresh Water Pressure System included an electrical diaphragm pump from Jabsco.
The heads were from Raritan. You'll still can find parts from them for the old models.
You still can find spare parts for the two original Whale Gusher 25 bilge pumps here (Although not cheap at all...!)
Some of the Banjers still keep on board the original gas water heater. Here you have them, still alive and kicking since 1924!
Note: Gas water heaters are not any more allowed for cabin installation, under the CE Recreational Craft Directive.
The first VHF sets mounted on board Banjers were those rugged and reliable Sailor radios with a dialing channel selector.
The Banjers' decks were covered with this excellent diamond-pattern anti-slip product.
Air heaters were optional in Banjers, made by this UK company.
ANCHORING
Warning!
This section is under development.
Some of the statements and conclusions are still provisional.
Rules to choose the Anchoring Tackle has been, till recent times, a matter of experience and sometimes even a matter of wisdom and wishful tinking.
Rules and Regulations of the several Classification Societies allowed (and still do) for simple formulae to choose a ships' tackle, based mainly in Britany style anchors and all chain rodes. As those are empirical, based on many ship's tests, thousand of feedbacks from the industry, and only consider good mud and sand bottoms as those found in the charts' anchoring spots, results are quite similar from one Society to the other. Nowadays engineers have powerful and precise calculating methods, used to design case to case permanent anchoring tackles for big floating structures as oil rigs, etc.
Working and fishing boats usually do not anchor, simply because they do not need to, excepting in specific situations not highly demanding. So anchoring is an skill not mastered at all by most of the professionals in these fields. All fishermen I know through my professional activity only know and use the local variation of the grapnel anchor, good only for rocky bottoms.
Yatching is probably the most demanding field for anchoring techniques and equipment, because of the variety of bottoms, weather and other anchoring spots conditions. But until recent times it was based on simple 'rule of thumb' or semi-scientific methods.
The better approach for anchors manufacturers/developers was to do several anchoring tests, results varying significantly from one manufacturer to the other, because they were made under different conditions: Bottom quality, depth, rode composition and length, etc., were not uniform, and manufactures having not standarized published data to compare their results with others'. So the only way of comparing was to perform their own testing against competition units. And some manufactures tend to 'bend' reality towards their interests and hide to the public the negative aspects of their anchors. Unluckily this still applies in many cases....
A more scientific approach is taken nowadays by designers, as well as several independent studies have being performed. But again the not standarized tests conditions make it difficult to obtain general conclusions, although well stablished myths are falling quickly down. Many owners still doubt, feel confused or believe they do not have enough knowledge when choosing their anchoring tackle, being to them the best source of information the feedback from the cruising community, through Forums, etc.
Just to try to help fellowmembers of the Banjer 37 Motorsailer Club to better choose their equipment or judge the existing one, I'll navigate through all (to me) available information, post it here, analize it, and then, with the help of other experienced members, try to arrive to some conclusions and recomendations to be used in our beloved Banjers. I'd very much appreciate all contributions.
Guillermo.
First let's have a look about what has to be taken in account when designing an anchor. I find these pages useful to this end.
From the pages of the Dutch firm Vryhof Ankers, specialized in big anchors for the offshore industry.
"We are all aware that real-world anchoring is more complex than an idealized mathematical model or lab test..."
"An anchor rode is not an straight link between the bow and the anchor..."
Includes an useful Anchor Catenary Calculator.
Now, we'll have a look to several anchors tests available in internet:
"Of the anchors tested, only five passed the threshold of 1,000 lbs. and only four could arguably pass as storm anchors. The holding power of those four exceeded storm anchor requirements, but failed to do so on a consistent basis."

"It would seem preferable for an anchor to not set than to set and hold at only moderate conditions"
"Anchors which come highly recommended, even those which are successful in the marketplace, may not perform in the real world."
"These tests were conducted in order to establish a reliable, controlled database for comparing the performance of various popular recreational marine anchors in soft muddy sea floor conditions."

From this Test Series, we can conclude that for soft mud bottoms, we should use devotedly designed anchors, as the Fortress FX, set at 45º. They have holding power/weight ratios around 100, which is outstanding.
On the other hand it seems to be clear that plow type anchors, as CQR, Bruce, Delta and the like, are not good for soft mud bottoms.
"All of the manufacturers of these anchors recomend them for boats between 33 and 38 feet in length..."
Test Series performed by the manufacturers of the Super Max anchor, not being enough accurate, in my opinion, due to the low number of tests performed and not rigurous enough method.
From the pages of Fortress anchors.
"If you, like me, enjoy anchoring in those small, remote coves, you are sure to have dragged your anchor at some time : no matter what anchor you use, poor holding or strong winds will have made sure of that." (Alain Poiraud). Interesting tets series, where the setting ability of anchors on sandy bottoms was observed. Very interesting conclusions on instability of Flat Anchors.
Comprehensive test performed by "When direction is reversed 140º. a third of the anchors never broke out, another third reset at some length, and two never reset".
Finding a mud site was not easy....
Value guide table from Practical Sailor's tests
Well, having read down to here through all of the previous Tests reports, I feel somewhat confused. Anyhow I tend to trust the tests marked 
. To try to help fellowmembers of the Banjer 37 Motorsailer Club to make their own decissions on what anchoring tackle(s) should be better for Banjers use, I'll try to arrive to some conclusions, based on my own experience and knowledge, as well as on most welcome expected contributions from BMC members and friends.
Some other interesting pages related to anchoring:
"The main and ONLY advantage of the chain is that it is the only and perfect mean to avoid chafing of the anchoring rode on agressive sea beds. Except for this point, chain has all the disadvantages..."
"If the chain splice is examined for chafe on a regular basis, we find no objections to the rope to chain splice from a strength reduction standpoint, as it appears close in strength to other components in the system and to commonly available nylon line."
Now, let's go on working on what is needed for Banjer sized boats:
CALCULATED ANCHOR CABLE TENSION IN WIND AND WAVES, FOR 36' KETCHS
The following table is based on Bob Smith's analysis of the force applied to sailboats of different sizes in wind and waves based on observations in the Columbia River. Correction factor of 1.25 applied for ketch rig. (Excerpted from The Sailing Foundation Anchor Tests)

(Rode scope of five times depth. Boat veered 30 degree to wind)
Notice that with a 63 knots wind (Superior limit for Force 11) the rode tension (equal to wind & waves force) acting on the theoretical typical 36' ketch, is only slightly less than the Bollard Pull estimated downwards in this page for a 27" diameter propeller (746 kg) in Banjers with the Perkins 4236. This means that even with full engine throttle, a Banjer would not be able to make a headway. In real life this is even worse at sea, because waves are really much bigger than those found when the Columbia River test, where fetch was (most probably) relatively short.

The worst time for an anchor to drag is in extreme conditions. Those situations often occur at night, on lee shores or when a vessel may be surrounded by coral heads, breakers or other boats. So we have to calculate our anchor for the worst expectable conditions, let's say the top of Force 11, 63 knots winds, as we have to put a reasonable limit, unless wanting to carry something like an oil rig's anchoring system aboard.
The tests we've seen upwards here, indicate that because most anchors do not perform well in rocky, kelp/weed-infested areas, a selection of suitability of bottom for anchoring, may be more important than selection of an anchor. Indications on nautical charts of bottom characteristics are very general. Investigation of holding ground is possible through experience and, if all else fails, experimentation. Since it is generally difficult to verify the quality of the set, the best insurance is personal experience with a given anchor design and its suitability for specific bottom conditions.
We know now what kind of forces our grounding tackle has to withstand. Now, how can we calculate what is needed for our Banjers?
I'll try to follow some recommended methods, commonly used by the boating and shipping community. But first we may have a look at the web sites linked inmediately down here, as I find they are helpful stuff to simply calculate the anchoring tackle, as well as having very interesting info.
Detailed information from the manufacturers of the Flook anchor. Although rigurous, is easy to follow. Includes an useful nomogram, the 'Anchor Computer'.
(Click on image to find it in Dunhulty's pages)
From Al's Software Sailing Page. Most useful. Most probably all you need to know about anchoring calculations, although some simple maths are required. You may download from there several useful spreadsheets, allowing you to simulate your rode configuration. Down here you'll find a link to download his Synthetic Formulae spreadsheet.

They also state the following: A “Lunch Hook” should be able to hold your boat in a 15 kn breeze. A main, or “Working Anchor” should hold up to 30 knots of wind. A “Storm Anchor” is for winds up to 42 knots.
And now let's put to work.
BANJER'S GROUND TACKLE ESTIMATION (Several Methods)
1.- Following different Rules and methods.
1.1.- Spain/CE
First let's use one of the possible recomended tables to choose an anchor and it's rode that are available around there. In Spain we have a compulsory regulation for the recreative market, based in CE's rules & regulations, as follows:
Anchor and Rode chooser, under the Spanish Rules & Regulations
Boat hull length Anchor weight Chain diameter (*) Rope diameter (nylon)
Anchor weight is supposed for what Spanish authorities assume as to being high holding power anchors
(CQR, Delta, Bruce, etc., and the like).
