As I had dry fit the stem fitting previously I put the bowsprit up without the fitting and marked where it would sit, then used the fitting down on the saw horses to mark bottom and top. The vertical part of the fitting is where the rigging attaches, and is 8mm thick. I clamped a bit of wood onto the bowsprit beside where I had marked out and drilled holes all the way through. Then chiseled from both sides with some final shaping with the wood rasp files.
Below shows the hole looking from the side at the bottom, note the angle of the rear of the hole to match the bowsprit fitting.
And looking from above. The hole at the top is shorter due to the angle shown in the above photo. I have put some epoxy inside on the wood, but more is needed to seal it up fully.
And a picture of the bowsprit and fitting sitting in place from the side:
While I was in the anchor well and had the drill out I drilled two drain holes each side from the corner of the well on a downward angle to drain out any water. These were 8mm as well, and got some epoxy with a cotton bud but more again needed. Looking at the starboard side from the inside of the anchor well:
And the port side where it goes out through the hull. Doesn't look much, and will have a fitting over it so water cannot be forced in as the boat moves forward.
I'm getting closer to ordering the engine, propeller, shaft and fittings but needed to shape the rear of the keel for better water flow to it (apparently!). Checked Mr Wipple's photos, marked out the rough shape with a texta then attacked it with an angle grinder fitted with a floppy disk. Disk was 40grit with ceramic bits in the sand paper and did the job.
Mark out shown on the port side. I previously had a half-hearted effort at shaping the rear of the keel with the electric plane before I rolled the boat over but it was not enough.
And after attacking it for a while. This is looking from slightly aft, note the sawdust. I had double mask and eye protection.
A shot close up from the side:
And a shot with a straight edge against the hull to show the roughly 25mm or 1inch taper. Look to the right of the shaft tube (which will be cut back to the wood for the shaft fitting) and you can see what needed to come off the starboard side.
I then changed disks and attacked the other side.
Here is a shot from aft before, note the disk on the grinder to the left of shot:
And after with some straight edges each side to give an idea of what was taken off:
Engine enquiries continue, as does prep for sealer/undercoat of the hull.
