I have a 1970 CM 38 and I absolutely love it. She sails and points like a hot knife through butter, and does well in strong wind and strong current
mostly due to her weight and racer/cruiser lines. Thick hull
, heavy boat, great lines. I highly recommend this boat to anyone, along with her sister vessels, the 34, 35, 41 and 45. In my 38, i've topped out at 10.5kts in perfect conditions heading back to Corpus Christi from Port Aransas, but thats not the kind of thing that happens very often. Shes a very fast boat over long distances and good The 45 was later rebuilt along the same lines by another company
That S&J 45 is pretty much my dream boat.
With the weight comes a need for greater wind to reach hull speed
and more area required if you have to tack upwind in a tight area. You have to have a decent sized engine
at least 25-30 HP. Also, unless you plan on making your V-Berth the primary bunk, (Mine is converted to the head
with the additional room added to the cabin) then you'll find that its a great fit for a single-handed sailor to spread out in. If you want 2 people to live onboard for longer than a few months or so, you'll probably be better served with that S&J which looks to sleep 3 comfortably.
As a CM38 owner, I'm always looking for help finding more information, especially for a boat of this comparatively rare vintage. So please, if ya know where to find any more info, go ahead and let us know!
