Speedboat modifications
Posted: Sun Sep 14, 2008 3:46 pm
Me and my good buddy are planning to build a speedboat some time in the next year (we both had periods of unemployment this year unfortunately so things have been pushed back). I've had this in mind for some time but only recently joined this forum (i'm also planning a sabalo) and saw that dk is on here too, so I thought I'd post this.
Our requirements are:
Suitable for coastal/estuarine use, so reasonable freeboard and self bailing
Range of at least 100miles, 40-50hp outboard engine.
Interior helm and navigator seating for cold weather and rain
space for two to fish
no longer than 17'
trailerable
The DK 16' speedboat looks very promising with some modifications. By scaling up the plans 6%, increasing the freeboard by 100mm and reducing the distance between transom and cockpit by half I've been able to add an enclosed helm to seat two with enough space between for access through a door&hatch combination. I believe the hull shape is suitable for a medium swell (i won't take it out in anything but good weather). I intend to use 9mm plywood with glass inside and out for the cabin top, it'll be s&g throughout but the pillars will be box section and the roof and rear bulkhead will be cross-braced internally. I've increased the height of the cockpit floor by 30mm in addition to the raise caused by scaling the whole design to ensure self-bailing.
What's everyone's opinion on this?
