[nota]

fresh or salt water sailing ?

banana shaped hobie cats do not point or tack well
they are good beach boats for shallow water
but not very well built as they delaminate [glass layers pull apart]
and new parts are over priced from hobie

cats like to flip
not good for small kids

I would look for a bigger boat for two adults and 4 kids
a 20ft++ centerboard with a small cabin like a Catalina 22

we lived aboard a 47ft F-glass houseboat
and used daysailors and sailing dinks to get ashore
owned a blue-jay, windmill crapi 4.3, bunch of small Chryslers , sunfish, 420, FlyingJr
and a wooden 16ft baldhead schooner
had a raven 24ft racer for speed sailing at 1100lbs

later got 3 hobie 18fts cats with C/Bs
but they arenot strongly built and all had problems
hobie holder monohulls are much better built boats
currently have a 14ft holder it is very strongly built
