Re the Compac 23.
Own a 23. Don't know anything first hand about the 27.
Am a serial boat
owner from J-27's. to J80's to Sharks and all manor of dinghies, and I love my Compac.
Great solid (I mean SOLID) little boat with roomy cockpit
and a surprisingly roomy cabin
You take this out in anything. If the wind
get up to 20knots just furl the jib
and plod along.
It is shallow draft
so you can take it anywhere, but you do pay a price
to sail usually have family
who are skittish when they get on a tippy boat. They will feel comfortable on the 23.
