Hi I want to fit a pedestal table in the cockpit. The boat has tiller steering. Any advise on securing the support socket onto the cockpit sole Thanks Tarn

Can you get at the underside of the cockpit sole? Seems like a pretty simple case of putting four holes through and backing it with fender washers and nylock nuts. Maybe toss in a backing plate to cover the load but it's probably not necessary. Make sure that you properly bed and caulk the holes. I overdrill the holes, fill with epoxy then drill through again and finally countersink to create a big bead gasket.

Hi David Thanks for that I was just concerned that the sole was constructed with a core between the top and bottom sides which may need support. I was considering fitting midship cleats but read about the above concern. I am now thinking about fitting cleats to the Genoa tracks. Anyone any experience of these? Regards Tarn

Hi Tarn,
Midship cleats make mooring alongside so much easier, I highly recommend them.
On our SO30i, I enquired through the agent and eventually was advised that I could drill the through the deck to mount the cleats with a backing plate in the normal manner, though no guidance on location. I was a bit reluctant to drill too many holes near the shroud u- bolts. However, by the time the answer arrived, I had made up two short ropes with a plastic thimble spliced in one end. I thread these through the upper shroud u-bolts, and tie it off at the lower shroud u-bolt. As we approach the dock, we thread a line through the thimble ready to drop over a jetty post or cleat, while the other end goes back to the winch cleat and locked off in the self tailer jaws. When my wife drops the rope over the post (we avoid low dingy jetties when possible) I pull the other end through the winch and we are firmly tied on. Easy then to jump ashore and fix bow and stern lines. Preferably also Spring lines. Once that centre line is on, the engine easily brings in the bow or stern as necessary with just a small amount of throttle. Once the bow and stern lines are on, the now short centre line can be eased and adjusted as a spring to avoid heavy loading.
I would be reluctant to mount the cleats on the tracks, as while they are quite strong in the directions of normal sheet loads, I would be worried about them for the side loading of mooring loads, which, while normally quite low, can sometimes involve heavy " snatch" loads in certain adverse wind conditions, particularly if there is a bit of sloppy wave action. Perhaps I am overcautious, but I think you would need to mount the cleats in a manner which avoids strong twisting of the track.
We have found the system works so well that we never did drill those holes for a cleat, I just tie in the short lines when we arrive at the boat and remove them when we leave, so they don't really get too much sun. I think I would also remove them once underway if we were doing long distance cruising. It is a balance of effort vs. convenience.
On your table, apart from a large backing plate, the main issue is location with respect to the tiller and main sheet, and what you do with the table and base when sailing. On our previous boat, we mounted a removable inverted "L" post on a bracket on the cockpit well side. It would even swing out over the seats when it suited the situation. I remember it as a simple welded bracket, and the main issue was allowing for the slope if your cockpit sides are not vertical.

I would go for it and install proper midship cleats. My SO 35 came with them factory installed, and they do indeed make things simpler.
Like rene460, I would worry about putting side loads on something not originally intended for that. Following through on that thought, I would never use the shroud U-bolts. Not only were they not designed for side loading, they are critical to the integrity of the mast.

Regards Tarn Check out section 7.2.1 of the West Systems manual on how to install hardware onto a cored deck. It's not difficult and if you do it right it won't leak, and even if it does it should leak into the boat not into the core. One additional thing I do is countersink all holes before applying caulk, for reasons explained here (I use polysulfide not butyl tape). David |

Hi Everyone big thanks for your advise. I’m going to read up about core construction and fit midship cleats and table socket Regards Tarn
