Had an interesting evening/night/early morning on Sat/Sun.
Around 4:30 PM we were down at the back end of Eshamy bay jigging for bottom fish when a 10000lb 27 foot seasport flagged me down and asked for help, his new diesel motor had snapped his outdrive linkage and his old 2 stroke kicker was dead (and wouldnt have had the range to get him back anyway). They were a nice couple so I told him I'd tow them back to Whittier, not realizing how long it'd take.
We hooked up my little 17 foot boat with its 75 HP motor and away we went. In spite of the size difference I figured we'd be traveling at hull speed anyway so the 75 would be large enough and a bigger boat/motor wouldnt go much faster than I could go.
We rigged up a 10 foot line cleat-to-cleat and clipped a carabiner to it as a pully and tied a 100 foot line to that. It worked okay but my nose kept wiggling about 5 degrees - made steering a bit of a pain. If I were to do it again I'd rig a much longer cleat-to-cleat line for better stability.
Going an average of 5.75 MPH it took us 9 hours to travel the 48 miles back to Whittier (took a break in the middle of it). Got in at 3 in the morning.
3100 RPM gave us 6.2 MPH and 2800 5.65, tried going up to 3600 RPM but all I got out of it was 6.7 MPH and I was burning fuel too quick to make it back with what I had onboard. Made it back on fumes, even after pouring my 10 gallon reserve into the main tank.
At least the water was smooth as glass, if it'd been rough seas I couldnt have done it safely.
So, any way I could have done it better? I'd never towed anybody that large or far before.
