On some yachts, like Sea Owl and some Feadship F45s, the side decks flanking the upper-deck lounge appear to be too narrow for regular use. Are they for decorations only? Or do they serve a practical purpose, such as allowing the crew to clean the large windows (poor deckies) without using a harness?
I haven't been on either of those boats, but the photos of Sea Owl look as if those may be full walk around decks. And from the photos of F45, I think they are more for style but would also make it easier to clean the windows. Tonnage is often an issue to be considered when designing boats. So, allowing for a side deck may decrease the tonnage.
Interesting... I think tonnage was definitely a concern in the F45 design. Aren't they all 499 GT already? ;-)
Yes, so you add anything to them and they exceed 500. There are a lot of boats built that are 498 and 499 GT. Just look at how popular 160-164' is as a size. Then Feadship hits that with a 146.49' boat because of the size. So whether it's the issue for the side deck or not, there is a lot of design work done to come in just under 500'. The measurements are obviously very carefully calculated and a miss of 0.2% would be extremely serious.
I'm not familiar with either boat mentioned. But I can tell you this, a toe rail is better than no rail out all by a very long shot. Even if you need to have a harness on, having somewhere to support your body with your feet, is a heck of a lot better than swinging in the wind.
