Thanks to all of you for your advice and some amazing photos.  Noah's reminded me that I also have a speaker to mount and now is the opportunity to do just that.

Many than ks,

Interesting conversations around the stern gland wear.

One aspect that should be considered is cutlass bearing wear and what the total alignment is through the cutlass bearing, stern tube and gland and coupling. I have just changed my cutlass bearing and noted that the shaft is not concentric in the P bracket, as indicated by the collets on the removal rig.  I studied the old bearing, as I have with numerous journal bearings on large rotating equipment units to determine the shaft alignment, and determined that it appears to have been running in the 11 o'clock position and that there was no rubber left in that area of the old bearing.  The new bearing is also compressed more in the same position indicating a lack of concentricity.  I have checked the coupling alignment in the past and repacked the stuffing box; but now I have the opportunity to split the coupling and after checking the shaft "journal" area for wear, check whether the shaft has changed its position within the cutlass bearing having been released from the engine coupling.

I would have thought that the problems with the stuffing box may arise from either coupling misalignment or a cutlass bearing/bracket problem since the stuffing box should float on the shaft.  If there is damage to your stuffing box gland it may be a symptom of problems elsewhere rather than being part of a root cause, in which case it may pay to look further rather than just change the type of seal.

Main Message Board / Fitting Radar on my 34 MkII Tall Rig

DIY Boat Owner recommends mounting the scanner just above the spreaders.  Does any member have experience of mounting a radar scanner on a tall rig?  I can think of a number of reasons why this might be a good location, including minimizing interference with the Genoa when tacking.

Have you actually fitted a larger tank over the winter?  I found out how little the 34 Mk II tank is in a  very messy way  Have yo considered using your macerator as an emergency bilge pump - much higher capacity that many standard pumps?
