Do I need the bulkheads?

The previous owner of my Helms 25 removed the bulkheads that the stays are attached to. Do I need replace these or can I get away with just backing it with a large plate to spread the force?

Yeah, you need them unless you would really like to become very well acquainted with your mast at a very inopportune time. Or the sea bottom. Or both.

Re: Do I need the bulkheads?

I'll be the dissenting opinion... you really likely only need them if you plan to sail the boat. If you never put sails on, you should be good.

Sorry... not meaning to belittle the problem, but yeah they are structural.

It all depends on how the boat was designed & built.

On most boats the deck is not designed to take shroud loads.

Bulkheads can be designed to do one or multiple jobs.
  1. Transfer shroud / chainplate load to the hull
  2. Reinforce / strengthen the hull
  3. Divide the hull into sections (rooms)

I don't know the Helms 25 - but it's likely that the bulkhead does all three, with the last being least important.

Re: Do I need the bulkheads?

Ok, thank you. I was unsure if they served a structural purpose or not.

Re: Do I need the bulkheads?

The original designer of your Helms probably thought that the bulkheads were needed structural support for the hull and why it was built that way.

Re: Do I need the bulkheads?

Hi Chris,

Or, put them in for hull support and move the shrouds to the outside hull maybe and put long strong pads under them and good backer plates inside the hull....... S'a thought....

Re: Do I need the bulkheads?

When you put the chain plates on the hull, the deck acts as a longitudinal bulkhead. There is no way a vertical pull on a chain plate will force a deck inwards, taking the load on edge.
