I have a lovely little Haflinger filly with whom I'd like to start driving. She's coming 4 years old, just barely started under saddle, with some ground driving under her belt. I've harnessed her, but never hitched her to a cart. I do have a breaking cart and harness available for use at my barn, and both are the appropriate size. She's 14.1 and well-built, lots of bone and very athletic.
A friend of mine recently got engaged and asked me if, a year and a half down the line, Nyneve and I might be able to pull her wedding carriage. I told her we wouldn't be able to pull anything very big, and she said she didn't care if it was small as long as it had a front and back seat (so she and her fiance can sit together while I drive from up front).
I've seen carriages of this type designed for a single horse before, but I've never been sure whether I could get one for a horse Nev's size. I'm certainly willing, especially size I'd have a nice long time to prepare my pony. (I wouldn't have considered it if I didn't, I have no illusions about where we are in the process right now.)
Are there smaller, multi-passenger vehicles that would suit this purpose? Would I have to have something custom-made? I am not ready to purchase anything yet, I'm just exploring my options.
Thoughts? Suggestions? Thanks in advance!
