I'm giving serious thought to the idea of an old iPhone and a water proof case.
The question about speed always comes up during distance races. During a long reach it would be nice to know how fast the boat is going.
The idea of a tapered main came to mind because double trapped upwind I, the crew, saw on the main a lot to keep the boat flat. Sometimes the boat will shudder when I let the mainsheet out and I think it is binding somehow as it tries to run through the pulleys. Given the cost of a tapered main I'll try some McLube and see if that makes any difference.
With regards to the 8:1 being class legal we very rarely race against other 20(s). We only make it to a few Hobie sanctioned regattas put on by the Arizona fleets and for many years now we have been the only H20. Because the number of boats has declined in recent years the Hobie and Multihull fleets are starting to combine events and we've started racing with the Mulithull , Porthmouth, fleet instead getting thrown in with the 18(s).
When the decision was made to upgrade to an 8:1 system no consideration was given to being class legal because we're almost never in a situation where it is a concern.
Calling all mountain and west coast H20(s)! Consider the H66/514 spring and fall regattas in sunny Rocky Point Mexico. If you show up and I don't have a class legal set of blocks you win, maybe
Thanks again for the input.
