What height to put the main berth?

I have had to do a bit of playing around with this.  It seems that the height called for in the Wharram plans only allows for a reasonably thin squab.  But...I want at least a 150mm thick innersprung mattrass so I figure it needs to be lowered a bit.

Adding to the complications is that I want to fit an 88 liter Vetus water tank underneath the berth at the foward end.  But...the tank is 800mm wide and it would have to be raised onto a shelve it is is to go across the hull.  Then that was going to present a problem if if I wanted to lower the base of the berth to allow for the thicker mattrass.

So, after scratching my head today I decided to run the water tank fore and aft.  It means a little less storage under the berth but at least there will be adequate clearance above the tank.

I have been asked why a Vetus water tank when I could have one built in glass or stainless a lot cheaper?  Well the short answer is that I really like pure untainted water and that is just not possible from a built in tank of stainless or glass.  The Vetus tanks are built specifically for water and they guarantee that the water is odourless.


Master cabin layout...

I spent the day at the yard today doing my best to think through the layout of the master cabin in the starboard hull.

When I was there on Thursday I arranged to have a rough mock up made that I thought could work.  This one done yesterday so I was able to reflect on it today.

In simple terms I plan on having a vanity unit across the aft cabin bulk head which would incorporate a shallow drawer and on the starboard side of the hull there would be a faucet and small sink.

Above this will be a cabinet with double mirrored doors.

On the inboard side will be two built in cupboards with shelves.   On of these which is forward of the steps will be used as a hanging wet locker.

I haven't figured out the steps yet, but these will probably be in stainless steel with timber treads.  I will decide the configuration of this when the cabinets have been built...which hopefully will be by next Thursday so I can review it before I fly out to China on Friday...assuming the impass at Bangkok airport is resolved by then.

The photo will give you a bit of an idea of what I am talking about...I hope.   Interestingly the amount of space using this configuration is surprising.


How about a toilet?

At sea this is not a problem as there will be a 'trapdoor' in the wingdeck for this purpose...but, when anchored in a lagoon with other yachts in the vicinity a little bit of privacy is desirable.

So, what sort of toilet is most appropriate? 

Over the years I have found marine toilets to be somewhat problematic both regarding blockages and odor.  Then there is the issue of holding tanks.  Although in many of the areas that I intend cruising there are no regulations governing discharges I don't think that it is fair to be pumping effluent into what may be a pristine anchorage.

Holding tanks like marine toilets can also be problematic so I considered chemical toilets with built in holding tanks.  But, I felt that they also had limitations.

In the end I found a marine composting toilet which it you accept all the sales material about it, would seem to be perfect.  It has its own built in holding tank which only needs to be emptied occassionally.  Also, apparently it has no smell and there is no plumbing to fail.

The one that appealed to me is called an Air head and is made in the US.  I contacted the GM Geoff and he was most helpful in answering all my, I bought one and that is on its way.

I think that they are quite remarkable and am confident that it will live up to expectations.



What genset to use?

I never want to run short of power as I will have a water maker on board as well as a small air con unit for the master cabin.

OK...I know that will draw criticism from some Wharram purists but hey...I am 62 next birthday and I have had my share of roughing it over the years.

Anyway, the weight that has been saved on the hulls by using high tech composite makes up for the extra weight of the genset which is 90kgs.

Of course I have a bit of fuel for it and the weight of the house batteries.

It is a DC genset and I hope that I don't have to run it for more than an hour a day even if I am using the air con unit which will not be every day as most nights I will sleep on the deck.  I am installing plenty of solar panels and the genset will have a 200amp alternator.

I did a lot of reseach on a suitable DC genset and was very tempted with the Fischer Panda.  They are exceptionally quiet which appeals as I hate noise.  I had two 12KW AC Fischer Pandas on a previous boat and when they were working they were great...but, they gave a lot of trouble and were very frustrating.

When I researched for other comments I found that I was not alone in this experience.  One person I found was an American who had a Fischer Panda DC genset and he ultimately tossed it out and got a simple genset made by Bret Somers of Onsite power systems based in Australia.  It is a very simple unit...and thus easy to I have ordered one and he is making it now.



Cabin lips have been removed...

When I arrived at the yard last week the lips on the cabin that I did not like had been removed as requested and the construction of the hatches had begun.

The fairing work is proceeding and the quality of workmanship is excellent and the team working on the hulls are being diligent and careful.

Alan a South African who has been living in Thailand for the last 24 years has been appointed by Raoul to communicate with me.  This has been excellent as Raoul is very busy these days with some major projects on the drawing board.

Alan is fluent in Thai and it is most helpful to spend time with him on the boat and communicate direct with the foreman to ensure there are no misunderstandings.

I went through my proposed interior layout today and they are preparing some mockups of what I want.   I am back in Bangkok at the moment and plan to go back to Pattaya on Saturday to go through the mock ups.  There has been good progress.  I will take some more photos and post them on the website within the next few days.


The holes for the hatches are cut...

Here is another photo before the 'lips' are cut off the cabin tops.

Starting to look like a boat.


Topsides take shape...

The topsides are now on both hulls.  I was very dissapointed to see that there was a lip on the forward and aft end of the cabin.  I was expecting it to be the same as Creed's boat in which they are removed.

I pointed this out to Raoul and it appears that it was an oversight in which the workers had been working off the original Wharram plans and had not noted that they should not be there.

No problem as Raoul has arranged to remove them...more soon.


I need to catch up these blog entries...

The last few weeks have been quite intense for me with a lot of business issues to attend to and I have been somewhat slack in bring this blog up to date.

I am in Thailand at the moment and have been to the yard twice over the last couple of weeks.  What I will now do are a series of short blog entries to try and bring it up to the present day.

The last photo's showed the hulls just after they were turned over.

Todays photo show the start of the decking on the starboard hull.
