[/size]As promised so far, with some five other tugs to be measured but due to the weather etc moan moan, the HEMBC fleet has not all been through scrutiny! I am sure someone could make a very nice chart of the above but my thoughts and consequential actions are to make our tug tow this year a tad more easier and open to more vessels/captains. So as can be seen there is a two way divide or maybe even three way.;
[/size]up to 2 pound
[/size]2 to 4 pound
[/size]over 4 pound.
[/size]This will hopefully be a good handicap system together with a opening of the competition.
[/size]What do you think?
[/size]Perhaps Mayhem members could add to the chart list with there own vessels or other club members tugs!!? This may help you when in the early phase of planning your new tug build to have a better 'guesstimate' (Star trek 'Data' comment) as to drive voltage etc combinations.
[/size]Wishing you all well
[/size]Happy tug tow competitions all.

By the by, I have a 6 bladed prop, a Sitek Kort prop and a Prop shop prop all the same size so will soon put each on in turn to my tug and try its bollard pull, there will be slight external factors but I think the results will be useful. If not  ... then please tell me. As this question as to what prop etc in a Kort often rears its head and it needs in my mind some sort of data/validification.
