>> Take a boat ride in the morning at 9 am on Lake thun,visit Speiltz,come back to Interlaken to take the carryon luggage from the Interlaken train station or from the hotel ... at around 1 pm Catch a train to Bern
>> So basically I cannot take a boat from Interlaken West to Thun at 9:30-10 am ?
So you are basically wanting to do a round trip Interlaken West-Spiez-Thun-Interlaken West, leaving around 9:30 - do I understand correctly? Your preferred plan was out by boat and back by train, from what I can gather.
Another option to consider would be to do it the other way around, as boats leave earlier from Thun: i.e. train Interlaken to Thun, then Thun-Interlaken West by boat leaving Thun at 9:40, arriving Interlaken West at 11:49. If you got off at Spiez, you would have to wait two hours for another boat, and would not be able to catch your train to Bern around 13:00. You might be able to fit in a visit to Spiez if you caught a train from Spiez back to Interlaken. You would need to check the timetable via the link Lucas has already given you. Personally, I think it woud be nicer to stay on the boat though, given your time constraints.
