Re: Mast foot rubber seal pad

Nick Newington

Hi Ruedi,

The pad under my mast is pretty feeble and crumbly. I have scraped it out and regularly blast it with fresh water. It is barely visible now. As for the rig tension, to my eye the main mast on Amelia could do with a touch more rake aft, so I have left the forstay and staysail stay and baby stay  as they were and tensioned the rest a turn or two. It is all bar taught and even when sailing in say 15 knots true wind the lee shrouds are still very firm. I have also had a good look at the mast base when sailing upwind at 9 knots boat speed, dropping off waves. There is no movement. So I am happy to leave it be until such a time that I pull the mast down when I will have a new Tufnol one made.

Happy sailing

Hi Ruedi

If the leak you are worried about is water getting inside the boat, then don’t. This pad is not intended to seal that.

It is made out of PU (polyurethane), 90 SH (“hardness”), 5 mm thick. Several A54 reported a short life span of this material. Mine was paper thin after 8 years. The Mizzen pad usually holds longer.

I have discussed this with a few experienced Amel owners and with a very knowledgeable Naval Engineer who build boats over 100 ft. and it seems that replacing it with phenolic laminated (such as Tufnol), would be an improvement. It is a little harder (103 SH), though. 

Regarding Amel statement that “Even if it looks ugly and very worn there is no need to change it”, I would only add that, as it gets thinner and thinner, you have to check and adjust the standing rigging.

Hi Folks 

The mast foot rubber pad on my boat is quite brown and very brittle. I’m a bit nervous that it will leak one day (see pictures). 
I heard from Barry “Lady Penelope II” that he changed the Mast-Foot Rubber Pad in Hieres recently. 


I asked AMEL and got the answer that they haven’t done it very often and I should not worry about it. “Even it looks ugly and very worn there is no need to change it”, Amel said. In Hieres they did it first time 2 weeks ago with “Lady Penelope II”. Barry mentioned the rubber was like fluid and I’m confused about the answers from AMEL. 
What is your experience and who has done it on their SM or 54 over the years? 


Thanks a lot and kind regards
