The Spyder is geared more towards performance than creature comforts. She does clear the class
rule minimum limits with some margin but it is not a huge margin.
Hence, comfort down below is spartan and limited to four narrow (55 cm wide at the widest) bunks and there is 1.3 m of sitting head room. Even though there are four bunks one should avoid being more than three on a cruise lasting more than a few days. There is simply not room for the gear four persons bring. Not in the climate we have in Scandinavia at least.
Cooking is done on two back-packing styled petrol stoves in the starboard hull. Utilising back-packing gear is generally a great idea on a boat like this since this type of gear is designed to be carried (compact and light) and quite developed nowadays. Rust might be an issue but not a big one in my experience. This might be due to the efficient ventilation of Scarlattikvarten. It is usually dry below apart from right after a particular wet ride and even then the water ingress is very limited.
The head is a glorified bucket with an air-tight lid. It is not stowed below but in the port fore-deck hatch.
