IOM bits arrived

A month ago i ordered some IOM bits from chrissails.
These are a Dave Creed build keel fin, rudder, mast-finn box and a plain bulb.

Everything was nicely packed and arrived undamaged.
details:

The bulb needs to be sanded, filled and painted, mounting holes have to be drilled.
There seems to be a stainless steel rod through the midle of the casting to prevent bending, it also gives a sharp end to the bulb, Clever :)

The keel's core is foam, in the middle there is a fullcarbon strtut approx. 12x4 mm giving the strenght, the skin seem sto be two layers of carbon on each side, 4 in total.
Thicknes is about 7% of the chord

The rudder is stiff, there are some moulding faults in the lower part, but not a big deal, i dont realy like the shape, because the lover edge, which is a v, does not align with the waterline if the strut is positioned vertically.

Mast-fin box is stiff, weighs 28g

I am happy with the investment, these parts will go into my first IOM boat.
And will be definately used as a reference when designing my own foils.
