Yes, when The Boat Guard pivots into the boating position - 45 degrees off the back of the boat, you are free to raise and lower your Bimini top.
Yes. You still have full use of your rear entry. When The Boat Guard pivots back into the 45-degree position, it is situated off the back of the boat somewhat over the motor. When you go up your rear ladder, you climb inside the loop of the cover. There is plenty of room to freely use your rear entry.
Yes. When the cover is in the boating position, it generally rests just above most towbars. The cover is present in the back of the boat, but when towing a tuber, it is necessary to have a spotter anyway.
Yes. The trailering position is all the way back in the 90-degree position and tied forward on either side. Watch the video Owner's Manual on the video page and it will address this.
The Boat Guard handles wind very well. When the cover is closed, it extends 12 inches beyond the front of the boat, and about 36 inches beyond the rear of the boat to cover your motor. Because the front and rear are open, the wind generally blows straight through. This open format also gives The Boat Guard exceptional venting. Since the wind blows through, there's no mold or mildew, and even dries a wet boat. See photo in Product Information page of a boat which went through Hurricane Irma.
