Hi im new to Iboats and new to the boating scene and i have acquired a 14 foot fiberglass classic runabout bbut have realized that it is too small for what i want to do so im looking in to getting a bigger boat preferably a newer 6 seater open or closed bow boat between 16-19' long but my problem is i have access to a 19 foot boat for free but cant afford a different trailor so im wondering if i can resize my trailor and get a bigger axle for my trailor. my current boat doesnt hang over the back of the trailor i have and it is an older style tilt trailor. any help would be highly appreciated.
