As usual a grand mix of lessons learnt.
Leaky side window in the hull of an Oyster 435 was found to have only 5mm overlap with the window frame.
Need to be very careful when positioning as the hole allows 3mm fore and aft movement with the possible result of only a 2mm overlap.
No wonder it leaked.
Needed to design a freeflow 100ltr holding tank for a southerly to fit in a redundant hanging locker - Tektanks may be pricey but their service is superb and given the complicated drawing I sent the proposed result looks really promising.
Beware of buying new Electronics that may have sat on the shelf a while.
A customer saved some money on a Raymarine e90w plotter but the internal software was well out of date and needed flashing with up to date software.
The gps needed to go on a separate backbone rather than through the network switch which resulted in ten miles of extra wire until we get in a 5 way plug - shame they didn't supply this rather than four 5m cables, grr.
When calibrating an oldish Cetreck 730 autohelm don't go too close to the end stops otherwise when is does its own calibration routine there's a chance it'll try to go beyond the end stop which resulted in a blown hydraulic hose.
The lower rudder bearing on a sun Odyssey is a actetal ring inside a big rubber bush pushed up into a recess in the hull.
The issue in this case was corrosion of the stainless rudder shaft inside the acetal bearing which essentially seized it to the shaft,
this resulted in the acetal rotating inside the rubber which wore away quite quickly.
New replacement is £350 ish with the chance of it happening again.
So we've come up with a new design which will fix the shaft corrosion at the same time.
One customer wanted new standing rigging which was fine as the existing was looking distinctly old.
There was specifically bad corrosion inside the silly white plastic coating that's supposed to prevent wear on the cap shrouds (same applies to guard rails - don't do it, its dangerous !!)
Another wanted new standing rigging but didn't want the forestay changed even though it was the same age but he insisted that as it was inside the furler spar "it will be fine" I didn't agree but the customer is always right??
The very expensive lewmar winch service kits (£40) don't include some of the serviceable parts like the bearings, plastic wear washers, spindles, but they do include bits for winch sizes you don't have - daft.
Splicing the core with Marlow 12mm covered dyneema halyards is hard work but worth it in the end
Fell off my chair when I saw a quote for a genoa cover from North at over £750 for a 40'
