Curved lifting foils

The F-85SR float lifting foil cases adapted for F-22R have been ordered

Back in the workshop

No available time nor energy for a while, but I am finally back in the workshop and will push on to get the boat on the water in time for our local event late August.

I will close off the water ballast tank with a sheet of plexi.  Will facilitate inspection, to learn if the system works.

Stairs painted and finshed.  I also choosed to paint the main bulkhead inside.  I use a cheap two part polyurethane paint.  No preparations other than removing the peel ply and a quick sand.

Water.  I use a 10 litre removable plastic tank with a tap.  Sits on a shelf in the backrest, and will be secured with a webbing.  Extra water can be carried in another 10 litre can under bunk next to daggerboard case.

Yesterday I started to glue the "mousefur".  Starboard settee back covered.  Suddenly the feel of the interior shifted from workshop to a cruising multihull.

Today I worked on the port side "mouse fur".  I use a water based wall glue, it is supposed to be adapted for a lot of difficult materials, time will show how it keeps up.  First, glue spread out with a trowel with 2mm fine grooves.

Mouse fur attached after about one hour of pre drying time. I didn't bother to remove the switches and stuff from the electrical panel when painting, so will have to do this later.  I made a removable table for the lap top next to the electrical panel.  I am able to log all data from the Nexus system, and the plan is to use these data to make a polar diagram.

Starting to look like a boat interior.  I am still to decide on storage solutions for the area in front of the front beam bulkhead, and this will not be finished further for now.  Would be nice to have some cushions made though.

And the ceiling.  Not looking forward to this, but will certainly be important to make it a bit cosier.  Will see if this is done now or postponed to a later time.  I am thinking of making some hand rails, and it would probably be wise to get the "mouse fur" in before those are mounted.

Slow progress

Time and energy has been scarce resources.  Short season will be the consequence.

However, the bailers for the water ballast tank will look something like it did on April 11th:

I have got a few details done with the interior as well, will show pictures later.  Working on the finish of the engine mount.  The bow is getting close to finished.

Long awaited reunion with the longboard

After almost two years of abstinence from fairing boat hulls it was good to finally get on to it again.  Filling the low spots, had to do it twice

Then the big fill

I will finish the area below waterline later, when the boat can be suspended from the ceiling, or rolled over, for better access.
Started to fill the engine mount

Fixing rudder case damages from the storm

Settee backs taped.  Still some details to sort out regarding water, laptop workstation, and heater.  I've come to the conclusion that my Wallas two burner stove with the fan lid is just too big for this boat and it will be put up for sale.  I'm not, however, certain with regards to what to use in stead, but I tend to think good heating is far much more important than excellent cooking abilities.

I think I made a bit too tight fit at the compression pads on the front beams.  This lead to the dismounting of both pieces when rigging the boat with unfamiliar crew last summer.  Being epoxy glued back on.

Water ballast.  The space below the swim step is roughly 50 liters, and looks like this from the inside.

I will put in two bailers in this area, one mounted the wrong way to provide filling.  The holes in the bulkhead will have to be closed somehow, I don't know how yet.  Controls for the bailers will be led trough the swim step and to a point under the traveller. The tape shows the position of one of the bailers on the outside, just above unloaded waterline

I removed the inside skin and the foam in this area plus about a cm.  Then 7 layers of 300 gsm glass was epoxied to the outer skin.

Then a HD filler is used to fill the rest of the excavated area.  For some, to me uncomprehensive reason, Google insist on turning this picture on the side.

Well, that's about it for now.

Small steps

I decided to beef up the new bow with some aramid

Starboard settee back is finally taped in. Makes sitting pretty comfortable, and also provides considerable room for storage.

Port settee back fitted with hatch for access to the electrical installations, ready for taping.

The bailers for the water ballast should be in the mail.  I will use two pieces of the Andersen super mini special, made for remote control.

"Demolding"

Removed the consumables and uncovered the new bow. 

Detail

Bow infusion

Unfortunately, progress have been much slower than anticipated.  The fact that I currently work out of town and spend about 20 hour a week travelling contributes to the fact that I hardly can find time, nor energy, to work on the boat.  I fear this will be another very late start of the season.

However, there have been some progress, and this evening I was able to infuse the bow of the main hull.  The main reason for infusing is that the foam is attached outside the existing hull with PU glue, and it is very difficult to get full bond this way unless equal pressure is being applied during cure.  As the foam is perforated, infusing will fix any spots of lacking adhesion and make a solid bow.

Carbon and peel ply attached using 3M spray glue.

Then the perforated release film attached with the same spray glue and resin distributing media using tape.

Epoxy feeding tube along keel and half way up the front.  Suction along upper diagonal edge.  Bag attached and infusion started.

During infusion.  Resin front clearly visible, and wetting out trough perforations in the release film following the front.

Film showing resin front progression

Infusion terminated.  Under vacuum waiting for the epoxy to cure

Engine tested on the new bracket.

I've also been able to make some progress on the interior.  Stairs being finished with edge taping.

Top of seat backs have been reinforced with a carbon tubing.
