Jim michalak's boat designs. 118 e randall, lebanon, il 62254. a page of boat designs and essays. at least with light weight sharpie sailing i pretty much believe that "flying" the windward chine, that is heeling the boat in the wind such that the windward chine is out of the water, can help speed things up a lot since there is a feeling. In general, if the two designs are similar in other respects, multi-chine boats, with more efficient hulls can be either quicker or more stable. folks looking for speed often pick a multi-chine hull. for paddlers who like the performance and feel of hard-chine boats they are the right choice.. If the chine batten is not long enough it has to be joined either by bolting as shown or scarfed and glued as for plywood construction. place the joint so that it will not collide with the main or intermediate frames. start bolting the chine at the bow and bend both sides working towards the transom..
An interesting multi-chine project as a stock boat featuring two different styles, layouts and rigs. the original concept produced the centre-cockpit, una ketch rig to give maximum boat the money wit loa. Boat speak terms we use to describe our designs. this glossary was originally published in our webletters. the purpose is to prevent the hard chine of the boat catching a wake or small wave on a sharp turn. on our boat designs, knees are used to reinforce the junction between the bottom and the transom, between the sides and transom.. The multiple chine hull eases the boat into an oncoming wave more slowly by absorbing the shock, as opposed to a single flat surface which would transfer all of the wave energy to the hull at one time. steps of the chine also suppress hull roll and heave by spreading out the impact of waves over a longer period of time..
