Re: Bestevaer 49ST

Fuel fill:

There are a great number of small details that go into yacht specification. I dislike the commonly used flush deck fuel fill used on many yachts. It relies entirely on an "O" ring seal to prevent deck water from entering the diesel tank(s).

Another alternative is to place the fill somewhere protected in the cockpit, but it can be hard to find a suitable spot, especially one that will still allow the use of a filtering funnel.

This design was suggested by KM. It allows the fill to remain on deck, but the pipe is raised above most of the water and the seal is is more substantial.






The water fill has deliberately been left as the conventional flush fill and the bulwark has no low drainage openings forward of it. This allows rainwater to be collected from the deck. The risk of a small amount of salt water entering the fresh water supply worries me less than water in fuel, especially as we have three water tanks and a watermaker.

Re: Bestevaer 49ST

As an aside.

Early in my career, I was a medic in emergency rescue for international situations. In my seven years, I learned a lot from the specialists whose skills I relied on to open the way for me to do my job.

One thing I learned was in order to combat dehydration, was to put a small % of saltwater in the drinking water. It actually replenishes the missing minerals that the body requires and makes you less thirsty.

Even here at home, in my cold water dispenser, After filtering the water, I add 1/2 teaspoonful of himalayan salt solė (water that has been saturated with the salt till it cannot absorb anymore) to 7 litres of water.

@84 minerals go back into the water. I also have a Japanese charcoal filter which takes out a lot of the chlorine and metals. You can taste the difference.

All this is to say dont worry about a little salt water in your saved water..

Now, Ken, don't you have cleats, standing rigging, hatches, stanchions, clutches, blocks, a windlass... this list could go for pages, on which to break your toes?

That's why I always sailed in boat shoes, never barefoot or flimsy sandals. Everything on deck is out to break your toes.

Having pumped out 8 gallons of water out of my fuel tanks, I like it.

That's because you've never installed a fuel polishing system. We did, and besides... even prior to that we've never yet had seawater in the fuel tank due to a poorly designed filler cap, the seals have held. Plus we tighten them appropriately.

Re: Bestevaer 49ST

We have had numerous handholds installed both inside and outside the boat. These are mostly aluminium tubes on the outside and stainless steel on the inside.

The primary purpose is to ensure there is always a place to grab on, important especially in a larger boat with a reasonably open interior plan. As well as their intended function, these rails serve as great mounting points for tablets, drink holders, monitors etc. The modern mounting systems such as RAM mounts are very versatile and enable virtually any moderately sized equipment to clamped securely to a rail. With many different sized arms, the attached device can be positioned to the ideal orientation. These are easy to relocate with a wide choice of fixed and removable clamps.

I think in addition to the normal chart plotter, we will have a couple of iPads clamped to to the rail just inside the companionway hatch. There is an overhang here creating a sheltered doghouse behind the pilot house, so I think the tablets might even be OK without any waterproof cover in most conditions. The roof also helps with sunlight visibility, which is one of the limitations of the tablet displays. The iPads can be used to display an alternative electronic mapping system (such as Navionics), mirror the chart plotter display (radar and charts and instruments) or mirror the Vesper AIS display.

This was a trial clamping one of our old iPads to the handhold just inside the companionway. This is a high position and I think it might be better lower, but one of the benefits of this sort of clamping system is that it can easily be moved.

Re: Bestevaer 49ST

Did you notice the faulty welds at the fuel deck fill? I like that idea much better than the flush deck fill however I like Dockhead's coach mounted fill better. So much for that opinion and I love your boat.

Thanks Deep Frz. You're right. That weld does not look up to their normal standard. I will take a closer look tomorrow.

Re: Bestevaer 49ST

Engine access:

This is important, especially if major work is needed on the engine. The gold standard is a walk in, stand up, engine room, but the space needed is large and is not achievable on a 49 foot yacht without other compromises.

We opted for several large removable engine panels. These are on the top, front and both port and starboard sides of the engine. It takes some effort to remove all the panels, but this would only be done with a major problem. One advantage of a pilothouse yacht is once the top hatch is lifted you have full standing headroom, so can work on the engine without crouching down the whole time.

There is also a strong point in the pilothouse roof to enable the engine to be lifted straight up.

To the starboard side of the engine is a workshop/technical room. This will house many of the systems that need more regular checking such as the the primary fuel and polishing filters.

This is the engine with the hatch in pilothouse floor removed. The access panel from the starboard side can be seen, but there are also large removable panels on the front and port sides:

Re: Bestevaer 49ST

Is that a thrust bearing for the prop shaft aft of engine? I think that means the engine doesn't take thrust and hence a CV type joint can be used for better vibration insulation? Did the transmission have to be specified with a different bearing?

When you install a python drive or similar the engine gearbox remains unchanged.....it's just no longer required to absorb thrust from propulsion.

Noelex et Seaworthy.

Do you have a date for the testing/shakedown?

Not an exact date, but most likely November .

I am flat out here working on a heap of projects - finishing cockpit seat cushions, splicing mooring ropes, sorting out the series drogue (I will probably buy the cones and attach these to tapered lengths of the line myself). I'm also starting to make the preserves for next season (chutney, jam, raspberry vinegar, lemon extract, harissa etc).

Lots of items need to be ordered from all over Europe and these take time to research and source. The next to arrive will be the under bed ventilation layer. Most of the instruments have now been delivered and these have been wired up at home so we can have a play with them.

Excitement is simmering along with the pots on the stove .

Haha someones excited that's great, as much fun as this project is I would imagine it's also a bit draining at times.

Good news for a nice recharge.
