My guess as well.

Thanks Peter, cape man and Tom.

Initially I thought it wasn't an air bubble problem - all of the the out of level compass card was submerged in fluid, well below a vey small air bubble at the top of the fluid's spherical enclosure.

Then the light-bulb moment. The compass card has a downturned edge so perhaps there was is an air bubble trapped under the compass card itself.

Sure enough. :D

Is this what you guys were suggesting?

Exactly. A small air bubble at the top is often there and generally does not interfere.

Thanks Peter. :D

Unfortunately my attempted repair to the stripped thread of the compass fluid refilling hole failed, and fluid was once again slowly leaking, so I've had to go back to square one.

I've attempted closing of the faulty filling hole with Sikaflex sealant and creating a new one.

I'll give the sealant a couple of days to set, then see if the fix works. Time will tell.

Thanks Jeff and Tom. I've set the compass aside to give the sika a three or four days to harden.

Today I installed a second set of rowlocks on Feather Pram. The first set installed a couple of months ago was for rowing solo. The second set installed today is for rowing with a passenger.

Referring to the pic below (the bow is to the to left of screen), when rowing solo, you sit on the centre seat/thwart, with the oars in the aft rowlocks to the right of the pic.

When rowing with a passenger, she/he sits on the aft seat, the rower sits well forward straddling the centreline seat/thwart running from mid-ships to the bow, and uses the set of f'wd rowlocks, which i installed today.

This arrangement allows f'wd-aft balance to be found when rowing with a passenger - a design achievement in such a wee pram. :D
