I just discovered this forum, joined and wish to say "Thank you" to all the posters for the information you so graciously share. We purchased a 1998 Sea Ray 240 Sundancer in March of this year and have it in a harbor in Oshkosh WI. The first weekend we launched, April 16th, 2005 was unusually warm, 70+, even got to 80 on Sunday. We put on 108 miles per the GPS and then had the temperature drop to 30â€™s and 40â€™s since. Using the camper top in the cold weather we have already put on over 50 hours and over 600 miles per the GPS. Although our experience on the water is limited we are quickly becoming experienced carpenters, electricians, plumbers and boaters all at the same time. We have enjoyed working on the boat and learning at forums like this. Our next plan is to take a local boaters safety course and build our real world boating experience. Thank you all for the quality information you have posted at this site.
