Not so.  If setup is the same as I have on my 1976 Contessa with the Petter engine, the cooling system had two injection points -- one close to the engine and one at the top of the gooseneck in the transom.  The copper lines were the connection. 

Since you have repowered and are not using these lines you may just cap and remove them.

Congratulations on your new boat!  You have begun a fun project.

In my experience, the sails on the Contessa are so small that you should not need the winches to raise the sails.  They can be easily sweated if more force is required.  Try sailing the boat -- if there is a lot of resistance then try to figure out its source.  Sail slides can be easily changed or lubricated and are much cheaper than a winch.

A winch does shine in situations where a large sail is under heavy load, such as during a bad spinnaker launch where you need to raise the head the last few feet to the top of the mast.  My boat uses a small one-speed Gibb winch for this application but the halyards go directly to the cleats.  The winch is mounted on a stainless steel plate which in turn is rivetted to the mast.  No pictures unfortunately.

If your boat has no winches on the mast, perhaps the halyards were previously run to the cockpit.  The extra blocks required introduce enough friction into the system that a winch becomes useful.  Do you have winches on your cabin-top?

It is important to sail the boat before going too far down the road of a refit.  You want to be certain that you are addressing real problems and not imaginary ones.  Along these lines, the Contessa is smaller than you think and some of your ideas for the boat may not fit.  I have certainly wasted a lot of time and energy trying to optimize the boat!  Some of my ideas have worked well, others I might try something else were I to try again.

Have fun!

Christopher

Good day all!

My 1976 Contessa came with a set of Aquatronic instruments.  Handsome analogue guages and a fascinating control box full of transistors instead of integrated circuits.

Aquatronic was made by a company called TekFlo in the UK.  That company no longer exists (of course).

This winter I found someone on E-Bay who was dumping a big box of this stuff -- from him I obtained a bunch of wind guages and their corresponding controller.  What is missing is the masthead unit.

I have since learned that all masthead units are not created equal.  Each counts in a different way.  Voltages are also different.  Since the manufacturer no longer exists what I need is either a dead masthead unit that I can dismantle to learn how it works, or a technical manual that explains how the masthead unit actually operates.

My shout-out to the group is in the hopes of tracking down more information (or a masthead unit!).

Thanks Paul!

I will be in touch directly.

Still looking for a trailer!

I also replaced my aging cloudy old compass with another. 

On the opposite side I installed an opening portlight for more light and air.  While it necessitated a big hole in the bulkhead, it was amply reinforced by heavy bronze frame of the port.

As I recall, the bulkhead was about 1/4" solid fibreglass in that area.

If I understand correctly, you will bond a piece of 3/8 smoked plexiglass over the hole and then install your instruments on the sacrificial panel.  To maximize panel strength in the area, as well as to tidy up the exposed wires and fittings inside the boat, consider adding a frame around the inside of the hole, perhaps 3/4" x 1-1/2" tall.  The frame will strengthen the hole addressing any concern that you had about panel strength and deflection.  Finish the box with an additional teak or plexiglass panel inside the boat.  This inside panel, screwed to the frame, protects the wires, hides the backs of the instruments and greatly strengthens what is now a structural box.

BTW, the Contest 101 is a handsome option and relatively inexpensive option.  It lets light pass to the interior and can be read from both sides.

Have fun!

Nice job!  To remove the mast you remove the mast base from the mast?

I have a love-hate relationship with the head door on my boat.  Mine is a simple flat door which makes passing it, or even having it clear one's knees when sitting in the v-berth is a challenge.  More recent boats changed to a bi-fold design which would help a lot.   A good curtain might offer sufficient privacy and be much easier to live with.

Always remember (I tell myself thisall the time!) that the Contessa is a scale model of a real boat -- she is easy to overload and gear like a heavy boat on davits rarely fits properly.

Here is a question -- were you planning to carry an outboard for the inflatable?  If so, it might have more power than the 6.5hp diesel in my boat!

If not planning on a separate motor then what about an inflatable canoe?  Relatively inexpensive, easier to propel and takes up less space on deck.

There is another version of this tank which is about half the capacity.  It fits exactly like this but tucks in under the lip of the seat so I kept more of the locker opening free.  My little Petter sips fuel and for my needs it is quite sufficient.

Nice install BTW!

Christopher

Shitty luck!

However, Kijiji is your friend!  There are at least half a dozen Contessa's between North Bay and Halifax.  Try the boats in North Bay and Ottawa!  There is a Montreal listing as well.  I know another couple of Montreal Contessa's whose owners may also be open to offers.  It comes down to what features you need and how much you are prepared to pay!

Good hunting!

Congratulations on your new boat and welcome to the forum.

Search the forums and ask your questions.  This website is a tremendous resource.

Check the route of the hoses.  On my 1976 Contessa the tank under the V-Berth is the holding tank -- sewage!  Sewage hoses regularly permeate with smell -- replace them and your boat will smell sweeter.

Look in the Gallery for photos.  There are zillions there.

From your description it may be that your berths have been converted to pipe berths which can conveniently fold out of the way.

For the V-berth there is a wooden insert which connects the two singles to make a relatively wide double berth.  Remember, this is a Contessa -- spacious it is not!

I also have an inflatable which I hate and therefore never inflate.  Mine lives in the V-Berth lockers adjacent to the hanging locker.

For our little boats I think a folding dinghy is the answer.  A Portabote tied to the lifelines would be perfect in my opinion.  And I have had plans for Fliptail from WoodenWidget for ages.

So many projects and so little time!

Good hunting.

Thanks to Oliver for the corrections.  Nice to know the builders were more on the ball than we guessed!

It would be interesting to see the effect of the lead ballast on the stability of the boat.  Lead would have lowered the centre of gravity of the ballast which should have made the boat stiffer.  I wonder if the difference is noticeable.


MatildaCO26 -- bravo!  I admire that you have a vision for your boat and have set about making it a reality!

I bow to John's experience on this one.  No doubt you can load a lot on a Contessa.  I can easily stuff my car a couple of times over with all my junk.

The pamphlet for my 1976 JJ Taylor Contessa lists her displacement as 5400 lbs.  This is probably for a very empty boat!

I once read that the boot stripe on the JJ Taylor Contessas was set for salt water.  Because of the difference in water density, the boat sits deeper in fresh water.  Perhaps this is why my boot stripe is always partially immersed.  Having gone to the trouble of applying more than half a dozen coats of Interprotect to seal the bottom of my boat, it seems ridiculous to leave relatively porous gelcoat exposed to long-term immersion along the waterline.  On my boat the boot stripe is cream in colour, and hence is easily stained.  Therefore it is the most scrubbed area of my boat, and potentially the most worn area of gelcoat.  As you might guess, I have decided to raise the boot stripe this spring!

Now to and4ew's question:  The cockpit drains are about 4" above the waterline.  If you put a bunch of heavy people in the cockpit, the stern will depress, and water will begin backing up the drains onto the cockpit sole.  While this can be entertaining on a hot day with a merry crew, it poses great risk for the boat.  Most Contessa's suffer from poor seals on the cockpit sole panel over the engine compartment.  For my boat, if the drains back-flood then water will begin to pour into the engine compartment and the bilge.  Which moves water faster?  Two 1-1/2" drains fed by gravity, or a single 1-1/4" bilge pump outlet fed by a manual or small electric pump?  You can see how a couple of heavy rubber bungs might become very useful! 

Commercial ships are very interested in the figure TPI -- tonnes per inch immersion.  This tells the shipowner or captain how much cargo he can load for each inch the ship sits deeper in the water.  We can use this same idea to answer and4ew's question.

The waterplane coefficient is the the proportion of boat relative to the proportion of a box defined by length and breadth.  That is, Cwp = AREAwp / (LWL * BWL).  Unfortunately I've never seen this figure listed for the Contessa.  However we can make some reasonable assumptions and from there find the waterplane area (AREAwp).  (Sorry that I have not mastered subscripts on the forum!).

-- LWL for the Contessa is about 20ft.
-- BOA for the Contessa is 7.5 ft, so a reasonable guess at BWL is 7 ft.
-- If we look at the top view of the boat and estimate by eye the ratio of boat relative to the LWL and BWL box we might use a figure of 0.7.  Thus our AREAwp = 0.7 * 20 * 7 ==> about 100 square feet.  For this exercise we will neglect that the waterplane area changes as the boat sits deeper in the water.

Picture a slice of the boat taken at the waterline, one inch thick.  It would have a volume of 8.33 cubic feet (1/12 feet * 100 square feet).  A cubic foot of fresh water weighs 62.47lbs.  Therefore each inch you depress the Contessa corresponds to about 520 lbs.  For salt water one could use 64 lbs/ft3.  Therefore each each inch of immersion in salt water would correspond to about 533 lbs.  Personally I would use the fresh water figure as it is more conservative.

Now you can see where we are going -- by these estimates, if I put 2100 lbs into my boat (people, batteries, fuel, water, food, books, beach toys, etc.) then my cockpit drains begin to fill the boat and I am at risk of sinking. 

One other thing to consider might be to estimate the weight of water in the bilge, up to the cabin sole.  This would be the point at which you would be able to see that something was very wrong down below.  Until then the level of water in the bilge is invisible unless you lift a panel.  If your fully loaded boat can be filled to the cabin sole and not experience flooding from the cockpit drains then all is well.

As for weight distribution, if you can get the weight low in the boat, such as at the bottom of the bilge, then you can make the boat slightly stiffer -- it will heel a little less easily.  Put all the weight at above the deck and she becomes very tender and will try to flop around and shed all that deck cargo.  I encourage you to experiment with a bunch of people on a hot day!

This is not a bad exercise for sizing a trailer too.  Let's pretend that my boat is hauled out and put on a 1600 lb trailer.  For a dry empty boat weighing 5400 lbs the combination of trailer and boat weighs 7000lbs and could potentially be supported by two 3500lb axles.  However, my fully loaded boat might weigh as much as 7400lbs until I get all the tanks emptied.  This means that the axles of the trailer would need to be rated for an all-up weight of 9000 lbs.  Trailer axles are sold in steps so I would have to change from axles rated for 3500 lbs to axles rated for 5200 lbs.

Good day all!

I am looking for the frames for a Natty Dodger for the Contessa.  I have a skin but not the bows. 

Given the cost to replace one of these, I wondered if there are owners out there whom have decided to not replace aging dodgers who might be interested in selling the hardware.

Thanks!

Ha!  I am glad it was not me!  It could have been though.  One year I launched with the valve for the head's overboard discharge open (for others reading in Canada it is illegal to plumb to this valve so it had never had a hose installed).  I happened to be present at launch and heard the water making a mess of the forepeak.  10 seconds and the valve was closed but had I not been present...

The problem for the Contessa is that the cockpit drain seacocks are virtually inaccessible if you need to get to their seacocks in a hurry.  I would have to notice the problem (i.e. water over the floorboards), not panic, find a screw driver (lockers are filling from below now), remove the cockpit floor panel (with so much water inside the boat the cockpit sole is now below the waterline so the drains are back-filling the cockpit) and then close the valves (which are now under water) -- all while more water rushes in faster & faster!  I would be sunk before I got them.

And of course there is the underlying assumption that someone is around to notice if I am not there.

I think that the real value of seacocks is the convenience of replacing hoses or related fittings while the boat is in the water.  BUT, if you maintain your boat, if you inspect, if you pay a little bit of attention, your hoses should be totally reliable.  And if you must have seacocks, put them where you can reach them in a hurry. 

I was on a big Hunter last year and noted that all the plumbing was led to one area in the middle of the cabin sole.  It was done for the builder's benefit since he could install all the through-hulls on a panel on a bench and then install them in the boat all at once.  From the user's perspective, it meant one stop shopping.  One area to check, one area to maintain, one area to run to if there is a problem.  While this is not practical for the Contessa, if I were determined to have seacocks and if I was prepared to re-locate the through hulls, then I would relocate the valves to the area between the batteries and the cockpit sole.  At least they would be in a place where I might be able to use them in a hurry.

The boat looks great.  Bravo on a good purchase!

Suggestion:  Go sailing with the rig as-is for this season.  The boat works well as-is and I think you should be very familiar with it before undertaking such a major change.  You need to know what you like and do not like about the boat, what your spouse likes or hates about the boat, and of course the costs for the project.  You may even decide that the Junk rig will not address the parts of the boat you don't like.  For example, the Contessa is tender and heels easily.  A junk rig will not change this.
