Dear list members,

We changed the rigging of our H27 Hipocampo this summer because the previous rig was very old and we did not know the date of installation. An inmediate effec was the increasing deformation of the hardwood block under the mast-step (it was slightly deformed before of the rigging renovation) as well as of the coachroof under it. After reading several posts in this forum and revising OYCOA Newsletter Autum 1996, we found that this is a general problem in the H27.

We think that the solution could be to place a SS plate (15-20 mm thick) under the mast-step. However, we are grateful for any suggestions and comments about this or other technical solutions.

All the best,

Susana and Antonio

You could do that, but most people just add side plates to the block and bolt them well into the wood. It's also possible that the riggers have over-tensioned the shrouds and stays. I'll e-mail a photo of ours. I can't remember without looking the exact thickness of the plates, but it was I think 6-8mm stainless steel, and that's done the job very well.

Dear Roger,

Thanks a lot for your reply and the private message. We think that the fiiting of SS side plates on the hardwood block will work perfectly; moreover, this solution is cheaper than our initial idea.

We do not know if we could use the original hardwood block or, alternatively, we will prepare a new block.

Best regards,

I have the same problem, I noticd after setting the new rigging a few weeks ago. Now i was thinking of replacing the old wooden block with a new one and setting a SS U-profile under the wood. I don't have a clue if steelplates along the old wooden step will do the job?
Someone can enligthen me?
David

noone? I read the autumn 1996 newsletter but can't read page 9-10-11 due to flawless print. Anyone has a better copy?
2nd question: is it absolutely necessary to strengthen the bulkheads?

Hey David,
I'd be hesitant towards putting (stainless) steel directly on the polyester. It cuts on the edges in the gelcoat.

Tank you that info, Ernst, I wasn't aware of that.
Now this is the new maststep I prepared at home: he is 2cm higher then the previous one, length and width are the same. 2cm will not be a problem for the rigging

I got an old piece from a former carpenter who worked a lot in ports. This one was a nice left-over from an job before his retirement. Maybe you could talk to local carpenters, they normally know someone to address to.
About oak, be sure it is white oak but better iroko, teak, mahagony.
This guy can help you to see the difference:


Here more info about white and red oak:

Thanks for posting this David, looks like a very tidy job. How is the mast step held in position? Mine has 3 large bolts through it.
