Bavaria Yacht Help! / installation of autopilot linear drive - photos

« Last post by blue-max on July 25 2024, 13:20 »

 Trying to figure out the best way to install the raymarine autopilot  linear drive in my boat - Ocean 47. I will need to design and have fabricated brackets going from hull to  the underside of  the aft deck with reinforcement to the lazarette  partition. If anyone can supply a photo of their installation that would be helpful - also the mounting of the rudder sensor.

I went through this as well on our 35 here in the US.  I ordered the gas strut through McMaster Carr inexpensively.  I assume they'd ship to the UK.  And acquired the end cap via the Seldon distributor that is located on the East Coast of the US.  Not directly, but rather through Fisheries Supply here in Seattle.  That may not be as helpful to you.  But once having the parts it was reasonably easy.

I, too, have the same problem that has plagued our boat.  So, I'll have to try the mould removal method and see if that garners success.

I think it's more likely to be a case of micro bubbles in the gelcoat, which are then broken by pressure washing and form voids in which dirt and mould can loiter.  I had the same problem on some areas of the superstructure on a Hallberg-Rassy I owned.

Yup, that's it, plus UV degradation of gelcoat over time contributes too. A Lagoon 38 S2 had it everywhere on deck except where it was shaded by the hardtop + tent.

You definitely want to have a care when pressure washing - a sufficiently strong pressure washer will take the gelcoat right off. Waterjet cutting is used to cut granite slabs

it's the first time I've heard that pressure wash causes gelcoat damage!  Was it a particularly strong pressure wash?  I wash the deck with pressure wash a couple of times a year, always before polishing, I haven't noticed anything unusual.

I used bleach with excellent results

This is a result of pressure washing the decks. Little holes get blown in the gelcoat, and water and dirt gets into them and go mouldy.

Get some mould & mildew spray. Spray it on and walk away. A day or two later it will be gone.

Hi, I have 2006 Bavaria 37. On deck I have noticed regions of tiny black dots in the gelcoat. They are only seen  from  up close. I’ve tried with 3M Medium (cut+polish) to no avail. Do you have any suggestions how to fix this?

Regards.
