Re the bow thruster.
The Athon I bought had a leaking bow thruster because the self tapping screws supplied had caused the housing holes to crack.
To avoid this on my new one I will discard the supplied screws and drill/tap 3mm to accept  SS M3 pozidrives.

Experienced opinion required please.
The MMM plans are non specific of a profile for the rear of the skeg.
This is where I'm at now, am I anything like expected?

Portgarth's skeg was increased in size from the original build. This picture shows the original and how it was extended forward and deepened.

There seems to be a problem with your pictures not showing. They may be too large for the forum.  If, however they are hosted, then that is where the problem may lie.

Had to spend far too much time filling pin holes in these Korts  >:-o
I think I'm going to stick with the primer colour and satin clear coat over this
What do you think?

I can see now that there isn't a very straight centre line in the hull moulding at the bow. Perhaps it has always been this way or just tired?
I like complete symmetry so some hard sanding and filling in order.

This is the Halfords red primer topped with clear satin lacquer. I think it'll do.

I've pinned the skeg with stainless steel servo pushrod rather than brass as suggested by MMM
This is before pushing home and glueing with Zap A Gap

Moving on from the bow and how it lacks symmetry and quality of finish either side of the centre line. The stern is just as bad if not worse. This picture doesn't fully capture how poor it is and I can't stand it like it is!
 so much Isopon is going to be needed to satisfy. Not what I expected from a ready made hull that cost as much as a full size bath tub.
This again is the PORT SIDE as if it's a poor copy of the starboard.
Any other Portgarth builders suffered this?

I'm happy with my work. Skeg is rock solid  :-))
One more pass of P38 and a coat of Z-poxy resin will see it ready for primer

Just a tiny bit of filler to finish the rectification once the primer is hard.
