i share your thoughts entirely. When we found the boat we wanted that had 90% of everything we wanted, molded in stairs were missing! This concerned me at first (I'm 75) but after climbing the ladder a few times (The hand rails & hand holds were precisely placed) the worry disappeared. Another benefit of the ladder is that when in the salon, we have a much greater view out the back of the boat....no molded stairs wiping out about 30% of the view. (On most boats.) Molded in stairs are nice (IMO) but finding the boat with the most desired features was priceless!
Since several folks afterwards have commented on age... I'll chime in about that too...
Your ladder does indeed look to be better angled than the ones we found when shopping for our third boat, and your point about stairs obscuring the view from the saloon is spot on... as with our current boat.
The ladder on our first boat (Mainship 34 III) was OK... for us... then. The big dogs (a Pyr and a big Golden) couldn't navigate it, though, and as time marched on, we became less comfortable with schlepping trays of goodies to the flybridge...
That was a great boat, and if we had her now, I think I'd have been inclined to research replacing the original with a purpose-built circular staircase of some sort. Or if that wouldn't work, now that I've seen the pic of yours, maybe just a straight ladder but with a much wider angle. Something that could solve the big dog/schlepping problems as well as do our current stairs.
When we shopped for this boat, we knew we wanted to return to a flybridge style -- mostly for visibility, but also for the additional entertainment/relaxing space -- but we also wanted to solve the dog/schlepp issues at the same time... so we looked only at boats with stairs. Hadn't seen any great examples of usable ladders. That narrowed the field dramatically and then we also learned even flybridge boats with stairs are not all created equal. Some stairs are uncomfortably steep, or uncomfortably shallow, or uncomfortably narrow... and then in some instances the stairs for some reason apparently caused the designed to reduce the useable size of the sidedecks. (??)
Anyway, now that we have stairs... or maybe I should say even though we have stairs... that age thing is still creeping up on us. And now, after a decent comparison, I think I can say that in most cases ladders are no better or worse than stairs from an aging point of view. I don't creak any more nor any less, these days.
OTOH, I can carry my own fully-laden tray of beverage and snacks and so forth up the stairs all by myself... even with the big dog racing me to the top -- or bottom, as the case may be).
But we can't see out of the saloon as well as you can. I can live with that, but your pic makes a useful point for folks who might be shopping.
