Wow! I'm jealous!
Although.............I advise you to seriously learn all you can about electrolosis/galvanic corosion and deal with it accordingly.
I know what I,m talking about. I made my living building aluminum fishing
boats for the AK salmon fleet for several years and I.ve seen some horror stories out there when guys didn't look after things!
If properly maintained, an aluminum hull
will last longer than you will for sure.
If not.............well, you'd better have some DEEP pockets!
Good luck! Have fun! Fair winds! etc.,etc.,
I sail on an all teak
, copper riveted, 70 year old ketch
. I love my boat but I'm still jealous!!
