My preference as well. I was showing a video tour of the boat to wife a week or 3 ago. I had to pause it and show her the L galley on their website. She concurs! I also must have a forward facing first mate seat on the bridge so that person isn’t sitting sideways. Maybe best done by a sliding backrest for first mate, that swings to allow that person to sit facing forwards whilst underway, and facing aft while seating with others around the table.
Your interest seems serious. If you have not done so already, I would urge you to contact Scott Helker at Helmsman. The links and numbers are on the website. Doing so early in your thought process will open you up to additional ideas, and you can get a bead fast on what is and isn't do-able. These boats are semi-custom, and each has been customized in some fashion for each boater.
Having said that, maybe it would be helpful to make a short list of the items and issues that buyers commonly will want to address.
1) Flybridge layout, that you already touched on. The common two selections are visible in various different videos and web pages. A single helm seat to starboard, with a U shaped settee and table are one. The second is two helm seats, the wheel centered, and an L shaped settee. I toyed with something different yet, but came back to the two helm seat arrangement. That decision was left up to my wife, and that's where she ended up.
2) Dingy. Carried on top, or on davits at the stern. Which leads to, do you want / need a crane?
3) Galley layout. You have already been there. The island, or L arrangement as you call it was what everyone seemed to go with until a few recent alternatives popped up. We are going with the island / L, because we didn't want to give up the space for the extra chair. The other way opens it up, but we didn't need a ballroom open floor in valuable space.
3) Galley equipment. Gas, or electric?
4) Generator? Air conditioning? If neither, a larger battery bank? I am east coast, and AC is a requirement. Period. Which means generator. Which leads to electric in the galley. You are in the PNW and it appears to me folks there go the other way on this for good reasons with the different climate and needs.
5) Provision to turn the pilothouse settee into an extra single or double berth? We did, with a single.
6) Main stateroom cabinets. Different layouts for the side cabinets have been done over the years. We liked the one in the recent videos and saw no need to go further than to say "we want that."
7) Obvious choices in countertops and leather color.
8) No electronics are included, because everyone wants something different. Pick it.
9) Arch or mast up top? We went arch.
10) Engine. 250HP is standard, and for the basic 7 knot cruising more than enough. We went a notch up for a bit extra if needed. Some have gone for a lot more, with trim tabs to accommodate it.
11) Doors. Recently the option opened up to have side doors amidships. Side doors on the cockpit are an option. And then double doors on the transom recently became an option.
No doubt I've missed something obvious and others can chime in.
I just have to repeat and emphasize that if you have something more in mind do not hesitate to ask. One chap doing a 43 has a very different head layout below being built. This isn't a pressure sales situation. Initiating a converation is quickly about what do you want, and possible ways to get there. Options. Problem solving more than sales. Try it, you'll like it.
Hope this helps.
