Boat Terminology Questions

Arches can support a small top nicely.

 

re terms: "sneezing"
Usually on fast(er) boats. A tendency of boat/hull to push water spray forward when pitching. It will then come aft (the boat goes through it). Make sure you have good wipers. Some cats or tunnel hulls can be very bad sneezers since the air under the 'wet-deck' compresses and ejects spray forward.

 

Thank you, I understand it much better now.
