Wow, impressive stuff kristoff,
I knew that you have quite a few different skills but didn't expect that kind of high quality finish of the furniture, just like a pro cabinet maker
fe the vineer on mating cupboard doors all in one piece, the width of the seems all even, .. etc...
very well done,

I wish you good progress, and hopefully the boat will be afload next summer :)
 
blimey that is A LOT of wood veneer, matching and fitting going on there!

nice progress!

Looks like you should be ready for the summer. Care to post a few overall pics to remind us of the state of the whole project?
We are running low on projects ATM in the mobo forum, so any help welcomed :D

cheers

Wow, your interior fit out is outstanding k_d. The veneer and cabinet work looks highly professional. Beautiful job. Much respect to you, and congratulations
 
Hi everybody!

With a lot delay some more pics from the upper saloon.
Progress is hard to maintain due work.



Floor and tables in place.






I've made some handrails to mount on the ceiling, but not sure yet if I will be using them. My wife thinks it's a bit old fashioned...





Things left to be done for the next weeks are finishing motor and rudder installation, placement of the diesel tanks.

A question: does anybody knows what is a correct/minimal angle for the rudder between the two endstops?
The hull is a semi-displacement type.
At the moment I measure only 58°. To me it looks a rather small angle.



Any advise is much appreciated.

Best regards from Belgium!
Kristof.

While investigating Autopilot component decisions I learned that 60 is minimum, 70 is common and larger are seen on certain vessels. Mine (32' planing hull mobo, twin prop & rudder) is 60 degrees and works fine.

Takes 6 full turns on the wheel - lock to lock - and eventually was fitted with an AP pump that manages a full stroke in 11 seconds (which is how you select pump capacity: The seconds needed for a full ram capacity shift).

Hope it helps :)

Hi Jimmy!

Launch date is around august. Till then we can use the parcel next to us for craning and getting ready for transport. The owner of the parcel next to our house will start building a house after that.
Until july a farmer is growing barley on that ground, so we can't move earlier or later...
Not sure if I well get that deadline, but I think it's still possible. A new deadline gives me more drive to get on with it. A certain level of pressure is needed to get me into action.
In the worst case (after august) we will have to lift the boat over the house... possible but far more expensive.
Still looking for a marina nearby with crane for the launch.

cheers! K.

Hi Spi D,

thanks for your reply. I think I need to make some adjustment then...
I could move the arm of the piston a bit closer to the shaft of the rudder so I get a bigger stroke.

Easier said then done, but I' am getting used to that :)
 
I believe rudder movement should match the force needed to make the hull respond. Excess movement might prove usefull for 'braking'.

On a twin prop setup you always have the option to add turning force by adding/reducing thrust on one prop, fwd or rev.

ok, I have only a single prop, but I want things to be right from the beginning.

Don't want to adjust to much things later when the boat is on the water.
Guess there will be surely enough things to adjust...
 
Rudders commonly have a lot of movement, restricted by (adjustable) end stop points.

If you go that way, you may design an extended movemet, later to be adjusted to meet needs
 
Good evening!

long time since last post, but finally the boat has left our garden and is in the water.
Since last post the technical stuff and a lot of painting is done. Due poor quality of the gelcoat I've decided to paint the whole ship.

A lot of sanding, filling and painting: started with epoxy layers (grey) under and above waterline, afterwards double coat for the colors. Thanks to friends and family for helping out!












The start of kitchencabinets:



rudder and sternthurster:



I will try to post some more pics of the launch etc..
Greets, K.
 
That is one good looking boat you got there, and what a job you have done, impressed to say the least. I would love a boat that big to fettle with. Out of my budget but you never know one day.
Keep up the great work, i will keep an eye out on your work :)
 
At the moment everything is going better than expected. There was some fear about levelling, stabillity and weight dividing. But that seems to be ok.
I thougt that I would have forgotten more things, but apart of cables for VHF and AIS most things are pretty well.

Till now only some minor issues, nothing that can't be resolved. Things that need adjustment for example: second shore power socket on the bow, placement of AIS and VHF antennas, radar, top- and achorlights, curtains, height of the swim platform, hatch lifters aft deck, drinkholder at helm, battery loading issue, small diesel leak on engine, fender holders, rudder metering, isolation engineroom, mast, heating adjustment,...
Most of these things were not ready due lack of time before lifting and transport.

At the moment the engine has about 20 hours, mainly on testing and a few short trips.
She sails well, good handling, but top speed is a bit disappointing. At maximum rpm I only get 17.5 km/h SOG.
Maybe there can be some adjustment here, but I am wondering if the screw dimensions are ok.

It's a semi-displacement hull, but at full throttle it seems that the only thing that is happening is making more noise and waves, but little more speed.
 
I suspect it's probably the pitch and / or diameter of your prop. There re quite a few websites that give a prop calculation, I'd also consider trying a 4 blader, worked very well for me on my previous 2 semi d boats.
