Re: cracked window
Friends of ours with a Beneteau (bought new) had issues with their Lewmar ports nearly right away. Through Beneteau and Lewmar they were replaced free of charge. Talking to Hunter may be worthwhile as far as sourcing replacements.
Drilling and patching would be short term solutions at best, I'd think.
