I have owned my 1974-built Jouster for about 6 years, and she suits me well enough, mainly day-sailing single-handed on Lough Neagh, in Northern Ireland. However I have just discovered a problem with signs of subsidence of the mast base, which is mainly evident by the crack in the internal fibreglass, directly below the mast (and above the entrance to the forepeak) in the attached pictures. I can also feel rather than see a slight depression in the coachroof just behind the tabernacle,,,,,
I have only just discovered the issue and have done no investigation yet. My impression is that the cracked fibreglass layer is not "structural", but rather a covering (very roughly applied) for some kind of beam that joins the two "doorposts" which are substantial box-section aluminium and rise from cabin sole to coachroof. Is there anyone familiar with this construction (perhaps used in other small Westerly's ?) and can tell me more ? Does anyone know if the deck had any kind of core that may have become wet and collapsed ?
My current theory is that either the beam itself (hidden behind the fibreglass) has begun to collapse due to corrosion or rot, or else the coachroof core has rotted, and sagged towards the (intact) beam thereby stressing the visible fibreglass covering to the point of cracking. Any comment or advice is welcome !
My other question relates to the tabernacle. Obviously I want to get the load off the coachroof, to reduce stress and enable repairs to be started. However, at my marina mast raising/lowering has always been done when craning-out, and even as a shared expense it has always been costly (£150 to lower and later replace). Under current circumstances I have no idea when or if there will a craning at all in 2020. I would therefore like to lower the mast by pivoting on the tabernacle bolt (with all due care wrt temporary shouds etc) but I am concerned that although there is some play in the bolthole through the mast there doesn't seem to be enough to allow the mast to pivot on the rear of its (flat) base. Hence the tabernacle might get torn out of the coachroof. Once again does anyone have experience of a similar installation. Incidentally, a Jouster is about the same size as a Corribee
Many Thanks, Nick
