Val, as requested details of how it went.
Installation was fairly simple. Had to drill slightly offcentre by 2-3 inches due to an obstruction below deck, however this is not noticable when you are using. Was a bit concerned with corrosion between the aluminum base and the stainless steel bolts so I used some yellow muck called Duralac. Apparently it does the trick, however it leaves a nice yellow smear around the fittings.
Went on a three day trip down south this long weekend. Seat worked very well both in sitting and leaning against. On the way down it was 36 degrees C (just under 100 F I think) so it got a bit hot and sticky against the vinyl. They do sell a blue cloth (polyester) version for a few $ more, however the white vinyl suited the existing decor in my pilothouse.
On the trip home we had a 20-30 kt tailwind with the boat rolling 15-20 degrees. Had no problems helming whilst sitting down and the sides held you in comfortably. When I needed a better view standing and leaning with the seat flipped up also felt solid and comfortable.
The view was also pretty good whilst sitting. Was able to spot some lobster pots when sitting. Can also view the electronic charts on the laptop from sitting down, however for detailed work your still need to stand.
The admiral also gave the seat the stamp of approval.
One mod I'll probably look at is installing a foot rest. To get the required height I had to use a 24" pedestal so your legs are hanging. One leg can sit on a bunk, however the other leg is left hanging and a small footrest would be more comfortable.
Also note that even though the seat can be adjusted fore and aft we did not adjust it over the three days.
Attached is a couple of photos. The cheeky grin is my six year old son.
One other mod I'll also have to do is a new drink holder. The existing one is now to far away and I spilt my drink when I was lazy and could'nt be bothered standing.
All up would recommend.
