I would see a good idea, but I've never seen that on any boat. On mine I don't think the bolts have worked loose, but I think its due to the neoprene gasket in between the joint used to seal it has crushed a little over the years.
Apologies for the delay - work has been manic, but now finally have some time to breath! It has been a while since I had the chance to do some drawings, so I'm a bit rusty. However it reminded me of how much fun it is though, and I was quite pleased to find that my twenty year old markers still worked! This was a quick sketch, & so proportions aren't quite right, however it should convey the ideas.
Looking at your drawings, and the rest of the interior, my view is to work with the web, rather than boxing it in. Firstly, it looks like it probably intrudes into the headroom space of anyone sitting in the saloon - if that is indeed the case, boxing it in fully would restrict usable seating space. Secondly on a yacht of this size, space is always at a premium & so this will maximise potential storage space too.
If headroom allows, then a padded rail could be run along the lower edge of the coachroof, which would hide the inner / uppermost part of the web. I think we discussed extra lighting - an LED strip could be run along the rear / outer edge if desired. If not, then a timber rail could run directly above the shelf & also internal to the locker.
If the locker is full height as I have shown, it will provide greater contained storage. The internal shelf does not need to be full length - if not, there should then be sufficient height for bottle storage (the bar has always been an essential feature of any boat in my family!).
The idea with the web is to have a veneered panel glued / laminated directly up against it to increase the size & thus form the side of the locker. This would also hide the tabbing in of the web too. The inner / upper most exposed part of the web would just be neatly finished off.
Anyhow, hope this is of use, and let me know if I can be of any further assistance, including (m)any design revisions to what I have shown!
So thoughts, once again thanks for taking the trouble to do that. Do you have a higher resolution version? I'm struggling to read some of your annotations.
So first thoughts are just a technicality, in your drawing the top of the shelf behind the settee is at the same height as the back rest of the seat. In reality the backrest actually extends past the level of the shelf & that provides a fiddle to stop stuff sliding off it. The height of that backrest can't be changes in any direction but higher, right now its at a good height for comfortable sitting against, its not possible to make it any lower. The shelf is also fixed at that height as well, there's no way I'm cutting it back out again!
I want to avoid a full height locker, to my eye its a bit too tall as there is a quite a distance between the deck & the shelf, the lower shelf is handy for dropping stuff like keys, phones & various other bits into, I also like the way it opens up the boat a little bit having that gap under the cupboards and the shelves. I actually have bottle storage in the middle of the table in the saloon, its not huge, but I only really keep onboard what I'm planning to drink.
I'll try your idea of bringing the cupboard right up to the web, I'll mock it up in some cardboard and post the pictures, I'm not sure if my OCD will allow it, but I'll give it a go!
Regarding headroom, my head just fits under the deck when sat down, the position of the front of the mock up lockers that I made earlier in this thread are in a good location for comfortable sitting, they just clear the back of my head.
I had to motor to Hull with no mast, not really a problem, lots of boats have just one motor... But on a sailing vessel it feels weird not having that back up of sails.
Due to work constraints and the fact that I only had a narrow window in which to get the mast put up (the local rigger is leaving for the police force) I ended up having the yard do most of the work on rigging the mast. Wiring, lights, assembly etc, all when I was away at work. They did a great job to be fair.
Now with the boat in the marina, lower shroud fittings attached, everything prepped it was the time for the moment of truth. I will admit I was pretty nervous at this stage, all those measurements I triple checked coming back to haunt me, hundreds of hours of work. In the end it went without a single hitch, everything fitted absolutely perfectly, to quote Patrick Bateman 'I felt the relief wash over me in an awesome wave'/
We still haven't got it set up yet, I'm letting everything bed in before I start to wind it up, but I'm totally stoked. I only had 5 days off work so no time to sail it, fitted the sails and cover, had a test run to make sure all was OK and it was. Although it looks like my mainsail could do with a little more hoist now.
I'm back home again this Friday so looking forward to getting out on the water. Watch this space.
