Great photos and observations High Current! I've spent a lot of time in my aft lazarette recently, replacing both bilge hoses (for the automatic pump and the manual pump) and adding a second pair of winches. My boat (a Mk1) also has a second pair of house batteries back there (where the water tank lives on the Mk1.5) which I recently replaced.

Glad I didn't come across some of the things you found!

The cabin sides are solid fiberglass, so no worries about leaking core. Just don't drill all the way through 😂.

Noah, the cabin sides on my boat have balsa core (visible when I removed the port-lights to replace them), so I think one should consider filling the old holes if you drill new ones.

Regards,
Derek

That's a clever design, looks like a cool idea. But the clear section is molded from polycarbonate... which is notoriously susceptible to chemical attack. So I wouldn't be using them anywhere they could be exposed to fuels, paints, cleaning fluids or chemical vapours.

Question to someone that has a "Loose Footed Main" : Does your Mainsail have a bolt rope???

My loose-footed main (Doyle) doesn't have a bolt-rope.

I also have a stack-pack (also Doyle) which prevents the use of a bolt-rope.

Cheers,
Derek

Antoni,
I followed Ron's tech note suggestion and added 3-sheave Garhauer deck organisers aft of the originals to get a better angle. My originals were only 2-sheave units and they had actually stopped spinning at all, so there was a little friction involved!

I still haven't removed the old organisers... will get around to it one day, but I'll have to grind them off as the mounting screws are seized.

I also replaced the 2-hole fairleads under the traveller with 3-hole fairleads and replaced a wacky set of old one and two-line rope clutches with a 3-line clutch on each side.

Here's a view of my new organisers (there are now 3 lines on each side):

Based on your experience, what do you think about the screen viewing angle? Sitting and standing sight lines are shown in the right view. Thanks!

Trevor, I don't have a protractor on the boat, so my guess is that the screen is about 35 degrees from vertical. It's definitely steeper than 45 degrees. But since I'm using the B&G mount, my screen is also adjustable.

Hi Ed,

my companionway steps are the same as yours.

Thanks Noah.

I'm still undecided if I will leave the hatches as shown, or invert them so they open upwards. That will be easier for access, so I may end up doing that. It will also require some way of propping them up when open, but that will be simple to achieve.

Noah, that's right, no aft water tank. This boat has a forward water tank under the v-berth and the usual starboard water tank under the seats next to the table. So yes, lots of storage space back there.

Alex is right, the aft bulkhead was entirely glassed-in and painted, no plywood panel there. You can just see there is a plywood panel on the port wall for access to the fuel tank, but not on the aft bulkhead.

Main Message Board / B&G Vulcan 7 installation - Mk I
February 23, 2022, 04:14:21 PM
Another little project completed this week... when I purchased my '86 Mk I it was fitted with a set of Navman instruments, all of which were dead, except the depth display at the nav station. In fact the instruments may not have been completely dead, but these old Navman displays had a problem whereby the connector for the flat ribbon cable from the PC board degraded and so the screen would just be blank. I looked at fixing these displays, but they were all very old so I decided to replace all the old instruments and sensors with an NMEA2k network, new sensors and B&G displays.

The most visible change is to remove the dead instruments at the helm and replace them with a Vulcan 7 touch screen chart plotter. A new depth/speed sensor has been already been installed, and I have a new wireless wind wand (yet to be installed) for the mast-head. Plus a cool new AIS-enabled VHF radio (B&G V-60B) yet to install.

The old instruments were in a smallish pod, here's how it looked from one of the photos from before I purchased her:


I was particularly taken with the clean and simple chart-plotter installations by RC (https://marinehowto.com/chart-plotter-mount-for-edson-pedestals/) and so I was looking at how to replicate Rod's approach with a small horizontal "shelf" on which to mount the Vulcan 7. I need to remove my entire pedestal to repaint the thing and replace the engine controls, so I was figuring I would need to wait until I had the pedestal removed before doing this job.

But as I looked at the brackets holding the old instrument "pod" I realised I could add a vertical Starboard plate and attach the Vulcan 7 to that.

Here's a view showing the Starboard plate attached using the old brackets:


And here's how it looks from the other side:


And finally, out for a sail on Corio Bay with the new chart-plotter providing me with charts and GPS-fed data.


I haven't finished installing the N2K network yet, so the Vulcan 7 is only displaying charts plus data from its internal GPS, but that's already a thousand times better than a set of dead 80's instruments!

For a while, I've been wanting to make some access to the lazarette from the aft cabin on my '86 Mk I.

So about a year ago I purchased three access hatches 510mm x 460mm (20" x 18") and yesterday I finally cleared out the lazarette and started cutting!

Here's a couple of photos of the results... first with the hatches closed:



And with the hatches open, you can see they give great access through to the lazarette:



I'm happy with that result. Next I'll re-route some wiring and the blower duct, then I need to start re-organising my storage back there...

Hi Erik, yes my MkI has a strip of teak screwed into those channels you have on each side of the bilge access panels. So I don't have those gaps either side.

I just installed the same 1 1/2 in valve to replace my holding tank outlet, which was leaking. Tru-Design valves are great!

Seems like an opportunity there to put some access doors or a hatch on that bulkhead to get access/storage?

Hi Noah, you're right! In fact I already have 3 large hatches already purchased, just waiting for me to empty out the aft lazarette before cutting some holes. The PO installed two extra batteries back there, so I have to make sure there is clearance for my jig-saw blade before cutting! I'll add pictures once this little project is done...

As long as you are back there you may want to remove both wood panels and look around. Fuel tank, thru hulls, water tank........

Glenn, looking at the photo which Junaido posted, his boat does not appear to have the removable wood panel on the aft wall of the aft cabin (my '86 Mk I does not have the removable aft wall either).
