Go to one which has a climbing wall, & bring a book. Then, when on the ground, try out several models of harnesses. Preferably ones with padded leg loops. Ones which have loops that you can fasten & unfasten/tighten while keeping the waist belt in place. AKA Drop Seat types.
Check out www.TrailSpace.com
for gear reviews
. Here's their harness page (for guys) http://www.trailspace.com/gear/sit-harnesses/
When you find your top 3 choices, all of which "seem" to fit well, with & without your foulies, plus several under layers on underneath of them. Then, break out your book, have them hoist you 3' off of the floor, & hang out in them while enjoying a good read... for 30min minimum. Do this both with, & sans all of your cold & wet weather
gear on; each way, for 1/2hr.
Plus, of course, try a bit of climbing in them, while dressed both ways.
If any of your extremeties start to go numb, or get uncomfortable, move on to the next candidate harness.
Also, see how tough it is to operate your fly/make a trip to the men's room, while wearing all but you top foulie layer. When in the harness.
I'd encourage you to have your partner do the same (without you Anywhere
nearby during most of the process), even if you'll be the primary one going aloft. As if your "replacement" has a full set of comfortable gear (comfortable; physically, & emotionally). Then it will make going aloft a non gender specific job.
And honestly, some of the best views on the planet are from up there. Ditto on opportunities/POV's for taking pictures.
In addition to the fact that it's essential for several primary crew to be both fully
comfortable, & competent, regarding going aloft.
Other than harnesses. Snag a few sewn runners, which have "foot loops" stitched over their entire lengths. Plus a few high load, locking, & auto-locking 'biners. Including several in stainless or titanium.
Also, some clothing
; base layers, long johns, & pants & shirts (including Polo's), made from synthetic fabrics with anti-microbial agents built in. So that, needs be, you can wear them for 2-3 days without them taking on any odors.
And maybe (?) some goretex socks?
Plus, also, some waterproof fleece/soft shells (top & bottom). They truly ROCK too. Especially the pants!
And if there's anything left over, waterproof, high output headlamps are nice. Ones which have battery
packs that slip inside of your jackets if you plan to sail where it's cold. And if you can find'em; ones which have both red (or green), & white headlamps in the same unit. So as to preserve your night vision.
--> Along with some quality rechargable batts, & a charger
or two for same. K--
Ah, & a perinneal fav; Chapstick with SPF built in. Plus some (spare) Croakies.
Also, one other fav is Aquasocks; both as deck
wear when it's warm; & for showering,. Plus trips to the shower
& back, as guests at YC's.
: Consider snagging some other components to flesh out your mast
climbing kit as well. But do some research
on specifics, prior to going to the store. In additon to trying out such gear, if possible.
On other people's boats, or the store's climbing wall.
