Is the division between small boats and large boats standing
headroom down below? That is a major factor for long term comfort when cruising or
living aboard. The other issue is capacity of
tanks. Sure, you can live on next to nothing in next to nothing for long periods of time (as a myriad of through hikers demonstrate every year on the Pacific Crest and Appalachian Trails can attest to, or the various sited sailing examples). But it ain’t necessarily comfortable!
You can not argue with a straight face that a given
small boat is more comfortable in a moderate or large sea compared to a larger boat of similar design? The motion is relatively faster and further on the smaller boat - that’s physics. Similarly, a larger boat can keep sailing in lighter winds on a big left over sea due to inertia and a higher rig, while a smaller boat will wallow.
I cruised with my parents on a series of boats from 18-32 feet, taking 3 (25 Folboat, 28 Great Dane and 32
steel Van de Stadt)
offshore from
British Columbia to
Hawaii (the smaller two) and around the
South Pacific with the largest. All were moderate to heavy traditional designs. The
Folkboat was an absolute sailing witch, with great manners other than awful rolling downwind. But no standing
headroom below (well, for me yes back then). The Great Dane was our first truly comfortable boat as we could stand up inside and had an enclosed
head for the first time that meant you could sit down without disrupting a bunk and removing the table. But she was still too small to deal well with slop and large wakes (lots of those in the PNW) hence we found the Van de Stadt before we set sail for the
Marquesas. We buddy boated with a 47 foot Swan (they had two
kids my age, very rare in the S Pacific in the late 70s and early 80s) and that boat out sailed us in all conditions, had ice cream(!!!!) and a
washing machine (my mum cared about that) and was vastly more comfortable in a variety of conditions. The only time we were happier with our boat was while lying to
anchor through a hurricane - we had much less windage and our storm
anchor was relatively twice as big as theirs. They dragged, we didn’t.
I’m not dissing small boats for cruising. Properly designed, built and sailed they’re as safe as larger boats (also well designed, built and sailed - don’t bring in not-like for like). But don’t bloviate about more comfort.
