I know HR352 boats pretty well. A HR352 will be the slower boat. The Corsair
will be more lively and nearly certainly will point higher. More fun to sail, no doubt.
The Westerlies have much more light down below, HR352 is pretty dark inside.
You will nearly definitely not find a HR352 with a grp deck
. Westerlies often come with grp deck
HR352 has a supreme cockpit
- deep, protected and comfortable.
IMHO Corsair could be the better boat for most owners. I would buy a HR352 only for its structural strength and ability to take rough conditions in its stride.
Otherwise both boats are very good tools from respected builders.
