Hi All. I’ve inherited a boat and it needs some work. My first question is, could you point me in the right direction for service kits for Windows? Also, can you service a seacock at sea?

Agreed. If anything goes wrong trying to do seacocks afloat, its incredibly difficult to stop the inrush of water for long enough to get something organised, usually ashore or from the local chandlery!From your questions in all respect you appear new to the boat maintenance world and my strong advice is 'do not' touch/service the sea cocks until the boat is next ashore.
Welcome
Need to know more about type of windows, but don't think there is any sort of "service" kit, just understanding how your type are constructed. The only seacocks that can be serviced are Blakes, and while it can be done afloat it is not advisable. If they work leave them alone until you have the boat ashore when you can take them apart and service them. Of ball valves and seized then they probably need replacing as there is nothing to service, although it is sometimes possible to free them.
Added some info on another message. Sorry, I have no idea what make it is. I’ll take some photos next time I’m there and post. It’s a cabin cruiser day sailer I think.Are you still with us Thomas?
Can we have more detail about make of boat and type of windows. (I.m surprised you didn't divulge those details in your first post)![]()
Thank you!Possibly an aside.
Many windows and hatches are made with 2 interconnecting frames, one outside, one inside. One frame will hold the glass/acrylic. The frames are sometimes connected with 'interscrews' also known by a variety of other names such as 'sex bolts'. These are a bolt (very small) that screws into a threaded cylinder which also has a bolt head. The head might take a slotted screwdriver, Alan key or Phiiips head. They are used as they provide a decorative finish and as you tighten them up they will pull toward each other squeezing out any excess sealant.
Interscrews are freely available - but I cannot suggest sources in the UK.
This is a selection of interscrews - they come in all shapes and sizes

Thanks for this. I will buying some just to have and maybe wait till the boat is out of the water to service.Here's a product that is designed to help you change seacocks whilst afloat, others may be available. Personally I'd lube the moving parts as much as you can whilst they're in place and leave changing them until you haul out. Have suitable sized soft wood bungs at the ready in case anything goes wrong - good practice to have these on bits of string by the fittings themselves at all times. If any are stuck closed and you need them open use penetrating oil, leave overnight & try again, rubber or leather mallet used carefully can help free them...
Your seacocks are Blakes. Info on servicing here yachtingmonthly.com/gear/servicing-a-blakes-seacocks-73248thank you! Please see attached picture of the windows.
Also, these are the two seacocks from my toilet. How do I open them? They are seased so not keen on doing it with the boat in the water.
