We are just about to complete the purchase of a 21 SL SPS and are really looking forward to joining the pontooning world. I have 3 run about boat in the past all with Mercrusier 4 cylinder I/O's so this will be a step up. We are not going with a trailer right away and will be keeping the boat in a slip here in Lewisville, TX. I was wondering what everyones thoughts are on not getting a trailer? I've always launched my boats but very appealing to be able to just get in and go. Am I making a mistake by not getting a trailer?
