Hello all. I am new to sailing and recently purchased a 1986 P18. Among many other projects this winter, I would like to replace the forward hatch (currently available from Precison) and both side windows, (apparently no longer in production). These windows are the long fixed ones, one per side. Any Ideas on replacements ,bearing in mind i am not to handy on F/G work, wouldn`t want to do a lot of cutting and fixing. Thanks, David
