the issue of air in the M15, for me, is really about where one sails. mrh219 where do you hail from? if you sai puget sound, san juan is. the straight of georga and places north getting cool isn't your challenge. during the day it might get warm, even hot .. but if the wind is blowing you will not notice as the water is always around 55 degrees. once the sun sets most folks must go to pants and sweatshirts even during the hot summer months (july/aug) because of that LARGE 55 degree heat sink. even on the hottest and long summer days by 10pm you will find it can get chilly. another fun event is each night you will hit the dew-point and find everything left on deck wet in the morning. puget sound sailing is also free of bugs. i can't remember having issues of bugs on the boat ... but if you go ashore it is a different situation. there are some shore locations where you will loose a lot of blood. a screen for the cabin hatch isn't necessary. from my 'lives' living in the midwest, south west, south and visiting the east coast the above doesn't count ... those places GET hot and sticky (excluding the SW where it is just HOT). in some locations i see the M15 cabin being a hot house. dave scobie M15 #288 - SCRED visit Scred's www-site: http://www.freewebs.com/m15-named-scred --- On Thu, 12/4/08, mrh219@yahoo.com <mrh219@yahoo.com> wrote: In furtherance of my aspirations to become a m-15 owner (aka "wannabe"), does anyone have any opinions about the benefits of increased ventilation in an m-15 such as: 1 air scoop on foredeck 2 small hatch on foredeck 3 small hatch on front of cabin 4 opening ports on sides 5 don't bother
