Porthole Size Comparison

Filed under: Building - Cabin — tomlarkin @ 9:35 am

Trying to decide on the porthole size and placement…

  • I’m mostly concerned with aesthetics – are they in proportion to the size of the boat and cabin? Are they the right height and location fore and aft?
  • Relative strength is not a concern – these are very heavy ports
  • Larger ones will make the cabin brighter and add more ventilation, but also make it less private, and the opening parts will be heavier and more obtrusive over the bed
  • Pictures of a bunch of tugboats with round portholes, for comparison

Five-Inch Portholes

5 Inch Portholes

Eight-Inch Portholes

I think they’re placed a little too high in this picture.
