Ok, so I’m a year behind the original schedule, but I’m nearly there. From my list a year ago: Engine install - done (new Yanmar 240s) Generator install - done (new Whisper Power 3.5kw) Steering gear install - done (new everything with large rudders) Paintwork - done (Awlcraft 2000 Ice blue hull, Ma...

David Davidson

Thanks Stephan. That’s helpful.

I am speaking with a metal fabricator next week regarding a radar arch and bimini set up. Do you have any more pics of your arrangement? Your side handrails look interesting.

David

David Davidson

Sstephan,
That is exactly the setup I’m fitting at the moment.
What width leaning post is that?
Do you have side screens also?
Do you find the bimini twists or moves when underway in big sea or wind?

Nice picture btw.
David

David Davidson

Mike,
Thanks anyway for looking.

David Davidson

Hi, I’m nearing completion of my total rebuild (90% done with 90% to go!) and am thinking about fitting a fighting chair. I would be grateful for any thoughts on best size and type for a 31 cockpit. It’s not for serious big game, but for occasional fishing and more often probably for the wife and ki...

David Davidson

Anyone know where I can get hold of some side steps? I’d love to get rid of the ladder arrangement.

David Davidson

I am in the process of installing a Frigoboat K35F 12/24v unit with a keel cooler. No cooling pump to run. Uses only 2 amps, and cools 20cu/ft. Anyone had any experience of these?

I have installed a top loading cool box into the galley worktop, with plenty of insulation around it.

David Davidson

Thanks for the advice Yannis. I have tested them with a hose wash down, and so far so good. No water in the bilges (I have 4 bilges now). I guess it may depend on how good your seals/latches are installed, and how the drainage is set up. I have blocked up the overflow drain from the boxes. That may ...

David Davidson

All my hatches have good seals and drain into shower sump boxes (3 boxes in total). I always like to keep my bilges as dry as possible.

Hi,
I am looking for a flybridge screen.
I have already glassed in the main front windows.

David

David Davidson

Marlin,
Thanks, I would be grateful if you could have a word with him. If he could take a pattern from the 31 near him, that would be a really good solution. I could drill and fit when I receive it.
Please let me know if you manage to make contact.
Cheers,
David.

David Davidson

Hi,
Can anyone suggest where I can get a new complete windscreen for a 31 FBC?
I mistakenly threw out all the fittings and old Perspex when I stripped the boat.
I’m in UK, so would need it shipped.

Any help will be gratefully received.

I put a Whisper Power 3.5 kw (continuous) forward of the fuel tank. They are supposed to be very quiet. It’s very compact and weighs only 68kg (150lbs). I had a shorter tank made, which is higher than the original, so I only lost around 40 litres. https://postimg.org/image/wlw8cg78z/ Will advise onc...

David Davidson

Carl, I lost tank area where the gen is now. So I moved the rear of the tank back around 6 inches, reducing the size of the aft bilge, and raised the height of the tank by about 6 inches. As I said before, I lost around 50 litres in all with the new, plastic tank. It wont affect my cruising/fishing ...

David Davidson

Hi, I've put a 3.5 kw Whisper Piccolo gen in just in front of the fuel tank. It's weighs just 70 kg. https://s5.postimg.org/733vzfnp3/image1.jpg https://s5.postimg.org/85e2hyysn/image2.jpg https://postimg.org/image/wlw8cg78z/ https://postimg.org/image/uu39hjg6b/ I put a new tank in, which it higher ...

You stay in places with carpets and drapes?
Wow, you're out of my league!

This hotel is where I normally stay:

It's an easy 10 minute ferry ride along to the show. No traffic, no parking worries!

David Davidson

The French are now reaping what they have been sowing on the Côte d'Azur for decades. Overpriced and bad attitude. They deserve it. We have moved our managed yachts out of there this year. That's about €5m turnover per annum they've lost!! Loved the Thatcher vid. She always made absolute sense to me...

David Davidson

That's the one! Nice looking boat.
Thanks.

David Davidson

It says "Sport Fisherman 31" on the side in the same style writing as a Bertram 31 badge.

David Davidson

If you click or touch on the pic, you can download the original photo. It's much bigger.

David Davidson

Saw this today in Sardinia. Never seen one like it. Anyone else? Was this a factory model or has it been modified?

David Davidson

I have just bought a set of Kobelt 2048 levers which I was very impressed with when they arrived. Good looking, well built. However, they are BIG. Whe I took them to the boat they looked REALLY BIG. With the 90 degree of lever travel either way I am not even sure they will fit on my 31 console. Has ...

David Davidson

Thanks Tony. Useful to compare, however with in/lbs, ft/lbs, Nm, Kgm and every other way of describing torque, it takes some effort to compare!! I have found a Vetus MTC125 ram with an HTP42 helm pump which matches my setup well. It's not been easy to get this sorted, even with talking to the "exper...

David Davidson

Copied, thanks.
I am renewing all, so am matching a new helm pump to the new ram.

David Davidson

Thanks for the input.
The existing system was definitely two dual acting rams.
My problem is that I am fitting High Tide rudders and tiller arms. The new tiller travel is longer, so I need longer ram travel.

I'll go with one larger ram.

David Davidson

Have 85" 1 3/8 A22 shafts on order with 2" wide flexible couplings.

Steering rams - originally had two, one each rudder, but is that necessary? I have a tie bar, so one cylinder should do right?
Anything I should know?

David.

David Davidson

What length shafts do you guys have?
Looks like I need 86 inch to put the 4 cyl Yannies where they need to sit.
Does that sound about right?

David Davidson

Hi, Offered up the new 4 cyl Yanmars today. They were so far aft that it wasn't right. I suspect the previous owner had shorter shafts made for the Cummins V504s. Does this sound right? Looks like I either need 26 cm longer shafts, or a big spacer. What length shafts should I need for 4LHAs in a 31?...

David Davidson

Hard top inspected and deal done at EUR 4K. Bargain. Raymarine radar is a 418d digital model, so may keep it for now. Frame is in great shape, no corrosion. Fibreglass top needs painting. Yannis, there is no way in the world I could get a top like this for less than 15k around here, believe me. Côte...

David Davidson

It's around a third of what a new one would cost to make around here. Getting one shipped from elsewhere would be even more, so I consider this a very good deal. The radar will be going on eBay, and the lights will go too. The frame will be stripped and polished, and the top modified for my needs, a...

David Davidson

EUR 5k

David Davidson

Sometimes you can't believe your luck. I have found this one for sale no more than 20 miles away!!! It is off a B31 and has a Raymarine radar, spotlight and stratoglass with it. Price is not crazy either. [URL=http://s58.photobucket.com/user/dontpresstheredone/media/B31%20hard%20top_zpscoozap77.jpg....

David Davidson

Thanks Yannis. None in South of France with hard tops, as far as I know.

David Davidson

Unfortunately not. They're not too common in Europe.

David Davidson

Hi, I am well into what has turned out to be a FULL refit of the boat. Fully stripped out and no original parts kept. Basically building a new boat from bare hull and flybridge shell. Massive job to do in 4 months, but we're going for it. I am trying to keep ahead with planning of parts required, an...

David Davidson

Interesting. My 4 cyl Yanmars and KH50 gears weigh just under 1,050 lbs I seem to recall. Not a great deal of difference from the original Bertram setup. I am also building an integral fuel tank and putting a 200 lb generator forward of it (just behind the step down). I am hoping this makes up for t...

David Davidson

Thanks Tony. I've got the engine install covered now. Next dumb question - what have you guys done with the seam on the Flybridge edge? The trim has been removed and it looks ugly. Grind it back and fibreglass a radius on it? Original fuel tank coming out on Monday. Glassing in an integral tank in i...

David Davidson

Hi, Total strip out almost complete, and planning new engines installation. I have read the following installation from Buddy Boy: [url]http://www.bertram31.com/proj/tips/engines.htm{/url] My question is why do the outboard stringers get cut to an angle? The current set up with the old Cummins engin...

David Davidson

Nice enough looking boat, but in my opinion doesn't have the aesthetic lines of a 31 and I am sure doesn't have the build strength and longevity of the originals. It is a modern copy of a classic boat, and just as modern copies of classic cars, it will not stand the test of time like the originals h...

David Davidson

Now in France and ready to start the refurb http://s58.photobucket.com/user/dontpresstheredone/media/image_zpsvjouwd9l.jpeg.html?o=3 http://s58.photobucket.com/user/dontpresstheredone/media/image_zpsevxy0n1z.jpg.html?o=1 http://s58.photobucket.com/user/dontpresstheredone/media/image_zpsuivrnnby.jpg....

Thanks Dug, I am actually considering this in my drive to simplify my project!

In need of a makeover!!

David Davidson

This the "before" shot. Ready for road transport across the Med to get a facelift. I can't believe the amount of original stainless trim on these boats. It seems a real shame to pull it all off! It's all it good condition after 45 years!! http://s58.photobucket.com/user/dontpresstheredone/media/imag...

David Davidson

Thanks Bruce.
Gear ratio 1.67:1
Copied on the air boxes.

David Davidson

Hi,
Getting a parts list together. Anyone know how/where I can find the through hull air intake and dorado boxes with the three hole type? There are others available, but they look the nicest.

David Davidson

Thank you gentlemen.
I will keep you updated of the project as I go.

David Davidson

Boat is currently in Mallorca. I am transporting it to South France near Nice for the refit. The 504s sound and run great, but are underpowered and HEAVY! Anyone want them? Been well looked after, according to all the invoices. I'll be running the boat around the Ballearics next Summer then ship it ...

David Davidson

Hi, Newbie to the forum and a new B31 owner. Just purchased a '71 FBC with original everything except it's got Cummins V504Ms (195hp). Starting after Christmas I am planning a total refit, engines, interior, exterior, wiring, plumbing, solid windshield, paint etc etc. Putting in Yanmar 4LHA STP 240s...
