Does the Navy still use the small boat of LSSC type? Like the one Dragon made in their Vietnam series? Other than the old Frogmen kit, this may be an option. Or one of the resin companies like Hobbyfan made some sort of Zodiac or other inflatable boat type.
Edit- ok, found it, Hobbyfan makes a Zodiac on a base w/5 SEAL figures. Looks nice but probably costs a bit...
