Snap davits and tender orientation when under way

[sprocker]

When under way with a tender (In our case a 2.3m Excell inflatable) on snap davits, is it normal to have the dingy on stand off arms in a vertical orientation (i.e. 90 degrees to platform), or
angled down as low as possible to keep 'air braking' to a minimum?

I intend to make up some long stand off arms to hold the tender at 90 degrees, so enabling use of the swim platform whilst at anchor and docking etc.

Do I also have shorter stand off arms to hold it in the 'low' position whilst under way? I need to hold it off the transom slightly as I don't want it to rub.

How do you gents do it?

I'm just in the process of fitting mine now.
I don't think aerodynamics really comes into it unless you are going seriously fast.

For me, it's more about usability and access to the bathing platform.
The last boat had the standoff arms at waist height, with the tender approximately upright. This blocked off the bathing platform for boarding.

Current boat, I plan to run much longer standoff arms from the top of the radar arch, and the tender will be tilted forwards slightly.
Downside will be that only a tall person will be able to attach/detach the arms (me).
Upside is that boarding access via the bathing platform will be retained.

(You can't hop over the side of an SC35 to board. Well, not without a trampoline/springboard and gymnastic skills)

Easy way is to loop the dinghy painter through the rear handles and secure to the rear rail. Pull in for travelling and when stopped lengthen the painter so that the dinghy can sit vertical (or a little rearwards) for easy access to swim platform.
Will take some pics next w/e

Similar problem for us, although with extended davits the tender is hung over the end of the platform so no problem with access when it is at 90 degrees.

We usually cruise around 20/22 knots which seems like the best speed for our Sessa. At 90 degrees the tender is approximately 50% stuck up above the transom, which makes me think there's a decent area to catch the wind and put strain on any fittings/fixings, hence my thought of lowering it whilst in 'cruise' mode. It will have to be easy to raise so SWMBO can get fenders/lines out once approaching a marina.

Good thought about attaching to the radar arch, I think GaryO did that with his S28.

Pics will be very helpful thankyou, all ideas much appreciated.

I found stand off arms to be a real nuisance as they create a trip hazard/obstacle course on the bathing platform.

If you can then do as suggested and run a line from the rear covers or a rail to the tender, you can then adjust it to your preferred angle and still have full use of the bathing platform.
